Python zip two lists into one

Learn Python by doing 50+ interactive coding exercises. Start Now #define list a and list b a = ['a', 'b', 'c', 'd'] b = [1, 2, 3] #zip the two lists together into one list list(zip (a, b)) [('a', 1), ('b', 2), ('c', 3)] If you'd like to prevent zip() from truncating to the length of the shortest list, you can instead use the zip_longest() function from the itertools library The original list 1 is : [[1, 3], [4, 5], [5, 6]] The original list 2 is : [[7, 9], [3, 2], [3, 10]] The modified zipped list is : [[1, 3, 7, 9], [4, 5, 3, 2], [5, 6, 3, 10]] Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics In the first example, how the Python zip function can combine two lists into one zip object whose elements are each tuples of length 2. It is important to understand that the Python zip function is actually capable of working with many different data structures. We will explore how to use Python zip with different data structures in this section Merge Two Lists into One in Python To merge two lists into one, use list comprehension. List Comprehension consists of brackets containing an expression followed by a for clause, then zero or more for or if clauses. The expressions can be anything, meaning you can put in all kinds of objects in lists

  1. Zip in Action! 1. Build a dictionary [2] out of two lists. keys = [drink,band,food] values = [La Croix, Daft Punk, Sushi] my_favorite = dict( zip(keys, values) ) my_favorite[drink] # 'La Croix' my_faves = dict() for i in range(len(keys)): my_faves[keys[i]] = values[i] zip is an elegant, clear, & concise solution; 2. Print columns in a tabl
  2. Python's zip () function allows you to iterate in parallel over two or more iterables. Since zip () generates tuples, you can unpack these in the header of a for loop: >>> letters = ['a', 'b', 'c'] >>> numbers = [0, 1, 2] >>> for l, n in zip(letters, numbers): print(f'Letter: {l}') print(f'Number: {n}').
  3. In Python, the built-in function zip() aggregates the elements from multiple iterable objects (lists, tuples, etc.). It is used when iterating multiple list elements in a for loop.Built-in Functions - zip() — Python 3.8.5 documentation This article describes the following contents.Get elements from..
  4. Today, we're going to take a look at how to convert two lists into a dictionary in Python. In short, there are three main ways to solve this problem. First, try taking advantage of zip and the dictionary constructor (i.e. dict(zip(keys, values)) dict (zip (keys, values)) )
  5. In Python, we can combine multiple lists into a single list without any hassle. In this article, let us explore multiple ways to achieve the concatenated lists. Some other standard terms are concatenating the list, merging the list, and joining the list. Using Naïve Method to combine lists in python; Using Python's extend function; The append functio
  6. To zip two lists of lists in Python, use the combination of itertools.chain () + zip () methods. # app.py import itertools listA = [ [ 2, 4 ], [ 6, 8 ], [ 10, 12 ]] listB = [ [ 1, 3 ], [ 5, 7 ], [ 9, 11 ]] op = [ list (itertools.chain (*i)) for i in zip (listA, listB)] print (list (op)

I'm not sure if this was your intention. If it wasn't, then you might want to extend the result list with the excess elements of the longer list. As @MrGrj pointed out in a comment: You could use izip_longest for Python < 3 or zip_longest for Python >= 3. Both come from itertools module To convert two lists to a dictionary using the zip function, you will join the lists using the zip function as we did, then you can convert them to a dictionary. Suppose we have two lists as follows: coin = ('Bitcoin', 'Ether', 'Ripple', 'Litecoin') code = ('BTC', 'ETH', 'XRP', 'LTC' zip() Function in Python 2.x This tutorial explains how to iterate through two lists/tuples at the same time in Python. We will use zip() and itertools.zip_longest() and explain the differences between them and how to use each one. We'll also see how the zip() return type is different in Python 2 and 3. zip() Function in Python 3. Given two lists, write a Python program to merge the two lists into list of tuples. Examples: Input : list1 = [1, 2, 3] list2 = ['a', 'b', 'c'] Output : [(1, 'a'), (2, 'b'), (3, 'c')] Input : list1 = [1, 2, 3, 4] list2 = [ 1, 4, 9] Output : [(1, 1), (2, 4), (3, 9), (4, '')

How to Zip Two Lists in Python - Statolog

  1. Get code examples lik
  2. The most Pythonic way to create a list of lists by zipping together multiple lists is the list comprehension statement [list (x) for x in zip (l1, l2)]. List comprehension is fast, efficient, concise, and readable. You can also extend it to the general case by adding more lists to the zip function: [list (x) for x in zip (l1, l2, l3,..., ln)]
  3. You can pass lists, tuples, sets, or dictionaries through the zip () function. Python has a number of built-in functions that allow coders to loop through data. One of these functions is Python zip. The zip () function creates an iterator that will merge elements from two or more data sources into one
  4. The zip () is a built-in Python function. It is used to create an iterator of tuples (known as zip object) from a list of iterables passed as arguments. Each tuple in the iterator contains elements that exist at a similar index in all the input iterables

How to Zip two lists of lists in Python? - GeeksforGeek

# Python Program to Map two lists into a Dictionary keys = ['name', 'age', 'job'] values = ['John', 25, 'Developer'] myDict = dict (zip (keys, values)) print (Dictionary Items : , myDict) Program to map two lists into a Dictionary Example 3 This Python map two lists into a Dictionary code is the same as above For various data analysis work in python we may be needed to combine many python lists into one list. This will help processing it as a single input list for the other parts of the program that need it. It provides performance gains by reducing number of loops required for processing the data further. Using + operator. The + operator does a straight forward job of joining the lists together. Zip and Sum [*sum(zip(l2,l1),())] Try it online! Zips the two lists together then adds all the tuples to make one combined list. The zip only works if the lists are guaranteed to be the same size, otherwise it truncates the longer list. Added the surrounding [* ] to transform it into a list as FryAmTheEggman suggests In this article, we'll examine how to use the built-in Python zip() function. The zip() function is a Python built-in function that allows us to combine corresponding elements from multiple sequences into a single list of tuples. The sequences are the arguments accepted by the zip() function. Any number of sequences can be supplied, but the most common use-case is to combine corresponding.

These tuples will then be passed to the zip() function, which will take these separate iterable objects (the tuples), and combines their same-indexed elements together into tuples, making two separate tuples. Lastly, through tuple unpacking, these separated tuples will be assigned to the first_names and last_names variables. We then use the list() function to convert these tuples into lists Let's take a quick example of Python Zip Function >>> for i in zip([1,2,3],['a','b','c']): print(i) Output (1, 'a') (2, 'b') (3, 'c') Understanding Python zip() Like Ziploc in the real world and .zip files in the virtual one, a zip is a kind of a container. Like a .zip file holds real files within itself, a zip holds real data within. It takes iterable elements as input and. In Python, enumerate() and zip() are useful when iterating elements of iterable (list, tuple, etc.) in a for loop. for loop in Python (with range, enumerate, zip, etc.) You can get the index with enumerate(), and get the elements of multiple iterables with zip().. enumerate() in Python: Get the element and index from a list Second, the zip function maps elements from the provided iterables together, returning a tuple. So instead of combining the two lists into one new list, as the module requested, you've created one new list of multiple tuples, comprised of elements from both original lists: [(2, 5), (4, -10), (5, 10), (10, 2) Python Zip Examples Invoke the zip built-in to combine two lists. The result is a zip object of tuples. dot net perls. Zip. With zip we can act upon 2 lists at once. Zip () is a built-in function. We pass it two iterables, like lists, and it enumerates them together

How To Use the Python Zip Function for Multiple Iteration

  1. The list one contains the first name of the employees and the list two contains the last names. The sequence of first name in the list one is the same / matches as of the second list's last names. Now, we want to get a single iterator that contains first name and corresponding last names of the employees. This is what Python Zip function does
  2. Use enumerate () and zip () together in Python. In Python, enumerate () and zip () are useful when iterating elements of iterable ( list, tuple, etc.) in a for loop. You can get the index with enumerate (), and get the elements of multiple iterables with zip ()
  3. >>> list1 = [3,2,4,1,1] >>> list2 = ['three', 'two', 'four', 'one', 'one2'] >>> list1, list2 = zip(*sorted(zip(list1, list2))) >>> list1 (1, 1, 2, 3, 4) >>> list2 ('one', 'one2', 'two', 'three', 'four') The above is not returning a list, but can be easily fixed
  4. In python, * is the 'splat' operator. It is used for unpacking a list into arguments. For example: foo (* [1, 2, 3]) is the same as foo (1, 2, 3). The zip () function takes n iterables, and returns y tuples, where y is the least of the length of all of the iterables provided
  5. Merge unique items from multiple lists into a new list (Python recipe) Suppose you have multiple lists. You want to print all unique items from the list. Now, what you could do is merge the lists into one_big_list (e.g., a + b +c), and then iterate over each item in one_big_list, etc
  6. > I wanted to write a function that would pair up elements from two lists into a single list of tuples. let rec zip (s1:'a list) (s2:'b list) = match s1,s2 with | h1::t1, h2::t2 -> (h1,h2)::zip t1 t2 | [], h2::t2 -> (Unchecked.defaultof<'a>,h2)::zip [] t2 | h1::t1, [] -> (h1,Unchecked.defaultof<'b>)::zip t1 [] | _ -> [
  7. At first, we convert a list into the set by using a set() Comparing two lists in Python using a Custom Function. In this example, we need to check the elements one by one whether it's available in List 1 or List2. # Custom python code to check if list one is equal to list two by taking difference # Define function name difference def difference (list1, list2): list_dif = [i for i in list1.

How to Merge Two Lists into One in Pytho

  1. Convert two lists into a dictionary in Python. While a Python list contains a series of values a dictionary on the other hand contains a pair of values which are called key-value pairs. In this article we will take two lists and mark them together to create a Python dictionary
  2. so basically it is a combination of multiple sublist and items and I want to keep them all as one single list items. I want to get the below output in another list -. 1. list_output = [ 'New', 'Group', 'Name', 'Details', 'Group', 'Name', 'Person', 'Phone','Number', 'Father', 'Name'] Reply. Find
  3. The append() method adds a single element to an existing list. To add multiple elements, we need: 1. iterate over the elements list. 2. append each element. Let's see the example: my_list = [DJANGO] for i in [PYTHON, PHP]: my_list.append(i) print(my_list) So, in the above code, we try to append [PYTHON, PHP] to my_list by
  4. In Python, elements of tuples and lists can be assigned to multiple variables. It is called sequence unpacking.5. Data Structures — Python 3.7.4rc1 documentation This article describes the following contents.Basics of unpacking a tuple and a list Unpack a nested tuple and list Unpack using _ (under..
  5. If a single iterable is passed, zip () returns an iterator of tuples with each tuple having only one element. If multiple iterables are passed, zip () returns an iterator of tuples with each tuple having elements from all the iterables. Suppose, two iterables are passed to zip (); one iterable containing three and other containing five elements
  6. g from a PDF or ZIP file into a custom binary stream like the preceding one. StringIO & BytesIO are high-level interfaces for Buffered I/O in Python

Iterate Through List in Python Using zip() 10. Iterate Through List in Python Using Itertool.Cycle 11. Iterate Through List in Python Using Itertools Grouper. 1. Iterate Through List in Python Using For Loop. Doing iteration in a list using a for loop is the easiest and the most basic wat to achieve our goal. As you might discover this article using some search engine while finding the way to. From the Python docs, zip returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. This is useful for iterating over two lists in parallel. For example, if I have two lists, I can get the first element of both lists, then the second element of both lists, then the third, etc There are three different ways of converting two lists into key:value pair dictionary. Lets look at them one by one (using above given example): 1) Naive method: By simply declaring a dictionary and then running a nested loop for both lists and assigning key:value pairs. #initializing lists


Zip lists in Python - Stack Overflo

In python, we can use the + operator to merge the contents of two lists into a new list. For example, We can use + operator to merge two lists i.e. # List of strings. list_1 = [This , is, a, sample, program] # List of ints. list_2 = [10, 2, 45, 3, 5, 7, 8, 10] # Merge two lists. final_list = list_1 + list_2 Some elements of the list is an another list. To convert nested list into a single list, I write a recursive function using collections module. My codes are . Stack Exchange Network . Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Visit Stack. Converts an iterable into an iterator. We could achieve the same result above with the Python zip() function in traditional for loop as below: def map_zip(l1,l2): result = [] # create empty list to hold result # iterate over the lists for item1, item2 in zip(l1, l2): result.append((item1+2, item2+2)) # add 2 and append return result if __name__ == '__main__': l1 = [6,4,8,9,2,3,6] l2 = [0,1. Just like the last lesson on inverting dictionaries in Python, we can take advantage of comprehensions to dramatically simplify this problem. Let's take a look: ethernet_devices = [1, [7], [2], [8374163], [84302738]] usb_devices = [1, [7], [1], [2314567], [0]] all_devices = [x + y for x, y in zip(ethernet_devices, usb_devices)] Enter fullscreen.

You can apply it to concatenate multiple lists and deliver one unified list. # Python join two lists # Sample code to join lists using * operator # Test input lists in_list1 = [21, 14, 35, 16, 55] in_list2 = [32, 25, 71, 24, 56] # Apply * operator to join lists in_list3 = [*in_list1, *in_list2] # Displaying final list print (\nResult: *****\nPython join list using * operator: + str(in_list3) Move data from step 2) to a master dataset (we will call it dataframe) Report 2-3 for the number of files; Save the master dataset into an Excel spreadsheet; Import libraries. Alright, let's see how to code the above work flow in Python. For this exercise, we'll need to use two Python libraries: os and pandas We can use the Python inbuilt functions for comparing two lists. Let's see. 2. Using Set Method. To compare two lists, we are using the set method. If the length of the two lists is different, the list can not be identical and return False. Else, Convert both the lists into sets. Compare these two sets. If the sets are equal, two given lists are the same. Otherwise, two lists are different In Python3, zip method returns a zip object instead of a list. This zip object is an iterator. Iterators are lazily evaluated. Lazy evaluation or call-by-need is an evaluation strategy that delays the evaluation of an expression until its value is needed and which also avoids repeated evaluations (Wikipedia definition). Iterators return only one element at a time. len function cannot be used with iterators

Write a Python program to map two lists into a dictionary. Sample Solution:- Python Code: keys = ['red', 'green', 'blue'] values = ['#FF0000','#008000', '#0000FF'] color_dictionary = dict(zip(keys, values)) print(color_dictionary) Sample Output: {'red': '#FF0000', 'green': '#008000', 'blue': '#0000FF'} Visualize Python code execution Python 3 program to Merge two lists and sort it : Python list is one of the most commonly used datatype. The list can hold different types of items. Each item can be accessed with its index. The index starts from 0, i.e. the index of the first element is 0, the index of the second element is 1 etc. We can access any element using its index. List is mutable. We can delete and change any element. Suppose we have two lists, we want to make them a list making pairs with . How can we do that? >>> a = [1,2,3] >>> b = [4,5,6] For Python 2.x: >>> z = zip(a,b) >>> z.

Python Program to Add two Lists Example. In this python program, we are using For Loop to iterate each element in a given List. Inside the loop, we are adding elements of the first and second lists If we assign this list to the slice values[1:1], it adds the values 'cheese' and 'eggs' between indices 0 and 1.. Adding Elements in Python Lists. Lists are mutable, so we can also add elements later.. We can do this in many ways. 1. append() We can append values to the end of the list.. We use the append() method for this.. You can use this to append single values to the list. In python, there is a function called zip_longest that canmerge multiple lists into a single list with the first elementbeing each first element of the original lists. I want to write asimilar function in C++. The function (named zip) should take twoconst references to vector and return a vector where each elementin the returned vector is the concatentation of the elements in theoriginal.

In this python programming tutorial, we will learn how to create a dictionary from two different user input lists. Our program will ask the user to enter the values for both lists and then it will create one dictionary by taking the values. Values of the first list will be the key to the dictionary and corresponding values of the second list will be the value of the dictionary The list-syntax in our assignment makes it more clear that we're unpacking a one-item iterable and then unpacking that single item into value and times_seen variables. When I see this, I also think I bet we're unpacking a single-item list. And that is in fact what we're doing. We're using a Counter object from the collections module here

How to save two lists with Unicode strings in csv file in

There is probably an easier technique that accomplishes the same thing but I've found this function useful in XML data processing [20-SEC SUMMARY] Given a list of list stored in variable lst. To flatten a list of lists, use the list comprehension statement [x for l in lst for x in l]. To modify all elements in a list of lists (e.g., increment them by one), use a list comprehension of list comprehensions [[x+1 for x List Comprehension Python List of Lists Read More In this example, I am printing two lists at the same time in a for-loop.#Shorts #programming #coding #short Python's map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping. map() is useful when you need to apply a transformation function to each item in an iterable and transform them into a new iterable.map() is one of the tools that support a functional programming style in Python

Using the Python zip() Function for Parallel Iteration

List comprehension along with zip() function is used to convert the tuples to list and create a list of tuples.Python iter() function is used to iterate an element of an object at a time. The 'number' would specify the number of elements to be clubbed into a single tuple to form a list. Example 1 The zip function takes multiple lists and returns an iterable that provides a tuple of the corresponding elements of each list as we loop over it.. Note that zip with different size lists will stop after the shortest list runs out of items. You may want to look into itertools.zip_longest if you need different behavior. Also note that zip in Python 2 returns a list but zip in Python 3 returns a. 5.1.2. Using Lists as Queues¶ It is also possible to use a list as a queue, where the first element added is the first element retrieved (first-in, first-out); however, lists are not efficient for this purpose. While appends and pops from the end of list are fast, doing inserts or pops from the beginning of a list is slow (because all of.

The same effect can be achieved in Python by combining map() and count() to form map(f, count()). These tools and their built-in counterparts also work well with the high-speed functions in the operator module. For example, the multiplication operator can be mapped across two vectors to form an efficient dot-product: sum(map(operator.mul, vector1, vector2)). Infinite iterators: Iterator. List comprehensions provide us with a succinct way of making lists, enabling us to distill several lines of code into a single line. However, it is worth keeping in mind that the readability of our code should always take precedence, so when a list comprehension line becomes too long or unwieldy, it may be best to break it out into loops Overview of List Operations in Python. List is a type of data structuring method that allows storing of the integers or the characters in an order indexed by starting from 0. List operations are the operations that can be performed on the data in the list data structure. A few of the basic list operations used in Python programming are extend. Difference between remove, del and pop in Python list; One response to Divide all elements of a list by a number in Python Troy Kelley says: January 28, 2021 at 8:23 am. If you want to divide a list of numbers divided into the first number, you can do the following: nbrlist = [48, 8, 2] #You want the 2nd number onward divided into the first number finaldiv = nbrlist[0] #The first number. Hello everyone, in Join Two Lists Python tutorial, we will learn how to join two lists in python. Already, we know list is an important data structure of python. Joining two lists in python is very easy. So let's see how to do them. But before proceeding further check the previous tutorial that explain you how to create a list in python and everything related to lists

ZIP : returns arbitary no of lists and turn them into tuples. FUNCITONS: def. Create a zip object by calling zip() and passing to it feature_names and row_vals. Assign the result to zipped_lists.

zip() in Python: Get elements from multiple lists note

You can split a list into chunks with this code: def chunks(l, chunk_size): result = [] chunk = [] for item in l: chunk.append(item) if len(chunk) == chunk_size: result.append(chunk) chunk = [] # don't forget the remainder! if chunk: result.append(chunk) return result print(chunks([1, 2, 3, 4, 5], 2) The first thing you need to work with zip files in python is zipfile module. This module provides tools to create, read, write, append, and list a ZIP file. This module does not currently handle multi-disk ZIP files. It can handle ZIP files that use the ZIP64 extensions (ZIP files that are more than 4 GByte in size) We'll be using the same files from that example: two text files called file1.txt and file2.txt. If you just want a new zip file with your files in it, then it's a matter of a few lines using. Adding two lists to create an alternating new list. list1 = [1,2,3,4,5,6,7,8,9] list2 = [10,20,30,40,50,60,70,80,90] sums_list = [] x = 1 while x <= len (list1): sums_list.append (list1 [x]) sums_list.append (list2 [x]) x += 1 print (sums_list) Essentially I'm trying to take list1 and list2 and alternate them in the new list sums_list but I. 2. Use list slicing with a step to extract the x and ys as separate tuples and the zip function to put them into a list of tuples. >>> coords = (51.901071, 7.543488, 52.002215, 7.692406) >>> coords [0::2] # extract every 2nd element starting from 0 (the first element) (51.901071, 52.002215) >>> coords [1::2] # extract every 2nd element starting.

9 Ways to Combine Lists in Python - Python Poo

While this works, it's clutter you can do without. This tip show how you can take a list of lists and flatten it in one line using list comprehension. The loop way #The list of lists list_of_lists = [range(4), range(7)] flattened_list = [] #flatten the lis for x in list_of_lists: for y in x: flattened_list.append(y) List comprehension wa The Concatenate operation is used to merge two lists and return a single list. The + sign is used to perform the concatenation. Note that the individual lists are not modified, and a new combined list is returned. Code: yourList = [4, 5, 'Python', 'is fun!'] print(myList+yourList) Output List items are indexed and you can access them by referring to the index number: Example. Print the second item of the list: thislist = [apple, banana, cherry] print(thislist [1]) Try it Yourself ». Note: The first item has index 0 For this purpose, we need the function zip(). The name zip was well chosen, because the two lists get combined, functioning like a zipper. The result is a list iterator. 1 This means that we have to wrap a list() casting function around the zip call to get a list so that we can see what is going on # printing the list of all files to be zipped print ('The following list of files will be zipped:') for fileName in filePaths: print (fileName) # writing files to a zipfile zip_file = zipfile.

How to Zip List of Lists in Python - AppDividen

Create a dictionary from the zipped_lists zip object by calling dict() with zipped_lists. Assign the resulting dictionary to rs_dict. # Zip lists: zipped_lists. zipped_lists = zip(feature_names, row_vals) # Create a dictionary: rs_dict. rs_dict = dict(zipped_lists) # Print the dictionary. print(rs_dict Now your archive.zip file will appear on your O.S (Windows Explorer) Step 3) When you double-click on the file, you will see the list all the files in there. Step 4) In Python we can have more control over archive since we can define which specific file to include under archive. In our case, we will include two files under archive guru99.txt and guru99.txt.bak I need help solving this python code, it is two items, I will include everything there is. Image transcriptions. Show all. Implement a function that takes in two sorted lists and merges them into one list, the new list must be sorted. The function MUST run in 0(m-m), where m is the length of list 1 and gthe length of list 2. In other words. the function cannot do more than one pass on list 1. Lists are zero indexed, so [0] returns the zero-th (i.e. the left-most) item in the list, and [1] returns the one-th item (i.e. one item to the right of the zero-th item). Since there are 9 elements in our list ( [0] through [8] ), attempting to access my_list[9] throws an IndexError: list index out of range , since it is actually trying to get the tenth element, and there isn't one Copy Elements of One List to Other Using Python Extend() In addition to above all, you can also add the elements of one list to the other list. To perform this task, you have to use the Python extend() and pass the list variable as the argument. Use the below-given example to extend one list to the other list.

How to use Split in Python The split() method in Python returns a list of the words in the string/line , separated by the delimiter string. This method will return one or more new strings. All substrings are returned in the list datatype. Synta Python Replace Item in List: Using a For Loop. You can replace items in a list using a Python for loop. To do so, we need to the Python enumerate() function. This function returns two lists: the index numbers in a list and the values in a list. We iterate over these two lists with a single for loop For now, we'll work with numbers. In Python, we declare the 2D array (list) like a list of lists: cinema = [] for j in range ( 5 ): column = [] for i in range ( 5 ): column.append ( 0 ) cinema.append (column) As first, we create an empty one-dimensional list Given two lists: What is the syntax to: Insert into such that now looks like ? Insert all the items of into such that now looks like

In order to use zip to iterate over two lists - Do the two lists have to be the same size? What happens if the sizes are unequal? Thanks. #9 Tim commented on 2012-10-29: Thx man helped me alot nice example btw #10 matt commented on 2013-02-08: re:#8, unequal list length: the result is truncated to the shorter list. See below for a discussion of how to use the longest list instead: http. Lists are a useful datatype in Python; lists can be written as comma separated values. You can change the size of a Python list after you create it and lists can contain an integer, string, float, Python function and Much more.

Python's list convention is shown in figure 1 where each item is accessed using the name of the list followed by a. Using zip() with list(), create a list of tuples from the three lists mutants, aliases, and powers (in that order) and assign the result to mutant_data.; Using zip(), create a zip object called mutant_zip from the three lists mutants, aliases, and powers.; Complete the for loop by unpacking the zip object you created and printing the tuple values. Use value1, value2, value3 for the values from.
