In some cases, we need to remove elements from two lists that are common. There are several ways to remove the common elements from two lists, for example, We can directly remove the common elements from both lists using for loop and apply remove() method on both the lists. Similarly by...
It is possible to delete list elements with remove, pop, and clear functions and the del keyword. Python list removeThe remove function removes the first occurrence of the given value. It raises ValueError if the value is not present.

Write a Python program to remove the first n occurrences of elements that are multiples of a specified number from a list. Write a Python program to remove the first n elements from a list that are greater than a given threshold value. Go to: Python Data Type List Exercises Home ↩ Pyt...
If the function applied to an empty list, it does not raise any error. Conclusion It is up to your discretion to use the way of removing elements from a list, either by value or index. Different circumstances require a different approach, therefore Python provides various methods of removing...
Thefilter()function takes a function and an iterable as arguments and constructs an iterator from the elements of the iterable for which the function returns a truthy value. The lambda function gets called with each element in the list, checks if the value is greater than100and returns the re...
