First, we will iterate the first list using for loop and check if the elements present in the second list or not. If the element is present, we will remove that iterated element using the list.remove() method in
Python has a provision of removing a range of elements from a list. This can be done by del statement. # List of integers lis = [3, 1, 4, 1, 5, 9, 2, 6, 5] # Removing first and second element del lis[0:2] # Printing the list print(lis) # Removing last two elements del...
In Python, the set.discard() method is used to delete the specified element from the given set of elements. To use this, first, you need to convert our List to Set. After removing the element from the set, convert it back to a list....
In this article we show how to remove list elements in Python. A list is an ordered collection of values. It is a mutable collection. The list elemetns can be accessed by zero-based indexes. It is possible to delete list elements with remove, pop, and clear functions and the del ...
We used thefilter()function to remove elements from a list based on a condition. 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. ...
Python List Exercises, Practice and Solution: Write a Python program to remove the first specified number of elements from a given list satisfying a condition.
Here in the example, we set n to2and usedmy_list[:-2], which means extract all the elements starting from index0, but do not include the last two elements. Here, we have usednegative indexi.e we count the index of the element from backward, here-2means the element "d". ...

Remove Duplicates From a List and Keep Order Dictionary keys are similar to sets since they have to be unique. A dictionary can have duplicated values but not duplicated keys. Prior to Python 3.6, dictionaries didn't maintain the order of their elements. However, as a side effect of changes...
