How to remove all the occurrences of an element from a list in python

Hello guy. How are you all? In this tutorial we will learn about How to remove all the occurrences of an element from a list in python. Sometimes in our list there are some elements which are unwanted and we want to remove it from our list. There this tutorial will help you. By using some methods like below we can remove the same elements from our list to multiple times. So without wasting your time lets learn this guys.

How to remove all the occurrences of an element from a list in python

  1. remove all the occurrences of an element from a list in python

    to remove all the occurrences of an element from a list in python just Use filter and lambda. Using lambda with filter it removes all the occurrences of an element from a list in python. If you have a list with name of List1and there are some elements which are not required for your program then by using lambda with filter you can remove it by this method. Lets learn this how it works. List1 = [10,12,41,1,12,1,0,1,0,1] wanttoRemoved = 1 result = filter(lambda val: val != wanttoRemoved, List1) print(list(result)) Output : [10, 12, 41, 12, 0, 0]

  2. How to remove all the occurrences of an element from a list in python

    to remove all the occurrences of an element from a list in python just Use filter with _ne_. By using _ne_ with filter you can remove all the occurrences of an element from a list in python. If your list have some elements which you want to remove than _ne_ remove it from your list and filter will give the another list of your wanting remaining elements. Thus you can remove unwanted elements from your list and get the new list. Lets see this. List1 = [10,12,41,1,12,1,0,1,0,1] List1 = list(filter((1).__ne__, List1)) print(List1) Output : [10, 12, 41, 12, 0, 0]

Method 1: Use filter and lambda

Using lambda with filter it removes all the occurrences of an element from a list in python. If you have a list with name of List1and there are some elements which are not required for your program then by using lambda with filter you can remove it by this method. Lets learn this how it works.

List1 = [10,12,41,1,12,1,0,1,0,1]
wanttoRemoved = 1
result = filter(lambda val: val !=  wanttoRemoved, List1) 
print(list(result)) 

Output :

[10, 12, 41, 12, 0, 0]

Method 2: Use filter with _ne_

By using _ne_ with filter you can remove all the occurrences of an element from a list in python. If your list have some elements which you want to remove than _ne_ remove it from your list and filter will give the another list of your wanting remaining elements. Thus you can remove unwanted elements from your list and get the new list. Lets see this.

List1 = [10,12,41,1,12,1,0,1,0,1]
List1 = list(filter((1).__ne__, List1))
print(List1)

Output :

[10, 12, 41, 12, 0, 0]

Method 3: Use list comprehension

By using loop you can remove all the occurrences of an element from a list in python. just create a variable with wantToremove and add the element which you want to remove from your list and run the code with for loop. It simply remove the element you want to remove and will give you the new list. Lets learn this.

List1 = [10,12,41,1,12,1,0,1,0,1]
wantToRemoved = 1
List1 = [value for value in List1 if value != wantToRemoved]
print(List1)

Output :

[10, 12, 41, 12, 0, 0]
