Remove multiple items from list Python

In this article, we are going to learn how to Remove multiple elements from python list with code examples. We are going to use set, list comprehension list append[] methods to remove multiple elements from the Python list.

1. Using Python SET

in this example program, we are converting the list into a set and finding the differences between two sets, and returning a result list.

Steps to delete elements from Python list with Set

• First we will convert the original list to a SET.
• We have converted the list of duplicate items to the SET.
• In the result list, we found the difference between these two sets and it gave us the results after removing the duplicate values.
• Finally, display result using using print[] method.

Output

2. For loop to Remove multiple elements from Python list

• In this example, iterating over each element of a list and applying a condition to identify the list elements that need to remove.
• condition is if list element is divisble to 4, then we will remov that from the list using the list remove[] method.
• Once we are done removing the item, we are printing the result list.

Output

3. List comprehension to Remove multiple elements by condition

Here in this example, we are using the list comprehension to delete multiple items from the list that are divisible by 4.The resulted list will contain the elements which will not be divisible by 4.

Output

4. List Append[] method to Remove multiple elements

Here we are looping over the elements of our list to check the elements of the list we want to delete elements of and appending them to result list.

• We have our list my_list which contains all elements
• we have a second list item_to_remove which has elements that we want to delete.
• So we are iterating on list[my_list] and matching item_to_remove elements. If the element does not exist then we append it to result_list.

This result_list will contain an element that is not part of the item_to_remove list.

Output

5. List comprehension to Remove list of elements

In this program example, we are checking the list [item_to_remove] elements that are not present in the original list[my_list]. It is just simple filtering based by using List comprehension with if statement and not in operator.

Program example

Output

6. Remove mutiple elemnst from list when indexes are know

This is a simple approach when indexes of the items know to us we are passing the index of items using del keyword to delete it from the list.

Output

7. Remove multiple-element within range with del keyword

Similarly del operator can be used to remove elements from the list by using indexes from start and stop range. We can specify the index as following to deleting elements from the list by using the del statement

Let us understand with an example

Output

Conclusion

We have explored different ways to Remove multiple elements from python list with code examples. We can any of them as per your requirement.
