In this tutorial, you’ll learn how to use Python to subtract two lists. You’ll learn how to do this using the popular data science library Show
Being able to work with lists is an important skill for any Python developer, whether a beginner or an advanced Pythonista. Subtracting two lists is less intuitive than simply subtracting them. Because of this, check out the four different methods provided below to find easy ways to subtract two lists! The Quick Answer: Use Numpy zip() function
Use Numpy to Subtract Two Python ListsThe popular One of the methods that Let’s see how we can use # Subtract two lists with numpy import numpy as np list1 = [10, 11, 12] list2 = [1, 2, 3] array1 = np.array(list1) array2 = np.array(list2) subtracted_array = np.subtract(array1, array2) subtracted = list(subtracted_array) print(subtracted) # Returns: [9, 9, 9] Let’s take a look at what we’ve done here:
In the next section, you’ll learn how to use the Use Zip to Subtract Two Python ListsThe Python Let’s take a look at how we can use the Python # Subtract two lists with for loops list1 = [10, 11, 12] list2 = [1, 2, 3] subtracted = list() for item1, item2 in zip(list1, list2): item = item1 - item2 subtracted.append(item) print(subtracted) # Returns: [9, 9, 9] Let’s take a look at what we’ve done:
Now, let’s take a look at how to use a for-loop to subtract two lists. Want to learn how to use the Python Python For Loops to Subtract Two ListsPython for loops are incredibly helpful tools that let us repeat an action for a predetermined number of times. Because of this, we can loop over our two lists and find the different between their items. Let’s see how we can use for loops to subtract lists: # Subtract two lists with for loops list1 = [10, 11, 12] list2 = [1, 2, 3] subtracted = list() for i in range(len(list1)): item = list1[i] - list2[i] subtracted.append(item) print(subtracted) # Returns: [9, 9, 9] Let’s take a look at what we’ve done with our for-loop method here:
Finally, let’s Want to learn more about Python for-loops? Check out my in-depth tutorial that takes your from beginner to advanced for-loops user! Want to watch a video instead?

This method actually also uses the Let’s take a look at how we can do this! # Subtract two lists with zip() list1 = [10, 11, 12] list2 = [1, 2, 3] subtracted = [element1 - element2 for (element1, element2) in zip(list1, list2)] print(subtracted) # Returns: [9, 9, 9] Let’s take a look at what we’ve done here:

You learned how to do this using the To learn more about the Can we subtract 2 lists in Python?Use Numpy to Subtract Two Python Lists
One of the methods that numpy provides is the subtract() method. The method takes two numpy array s as input and provides element-wise subtractions between the two lists.
How do you subtract between two lists?subtract two lists using Zip() Function
In this method, we'll pass the two input lists to the Zip Function. Then, iterate over the zip object using for loop. On every iteration, the program will take an element from list1 and list2, subtract them and append the result into another list.
How do you sum two lists in Python?How to find the sum of two lists in Python. list1 = [1, 2, 3]. list2 = [4, 5, 6]. zipped_lists = zip(list1, list2) `zipped_lists` contains pairs of items from both lists.. sum = [x + y for (x, y) in zipped_lists] Create a list with the sum of each pair.. print(sum). How do you subtract two elements from the same list in Python?between them.. Method 1: Using Remove() Method.. Method 2: Using List Comprehension.. Method 3: Using Set's difference operator.. Method 4: Using Python Set difference() Method.. |
