Remove all particular element from list python

Python List remove[]

In this tutorial, we will learn about the Python List remove[] method with the help of examples.

The remove[] method removes the first matching element [which is passed as an argument] from the list.

# create a list prime_numbers = [2, 3, 5, 7, 9, 11]

# remove 9 from the list prime_numbers.remove[9]

# Updated prime_numbers List print['Updated List: ', prime_numbers] # Output: Updated List: [2, 3, 5, 7, 11]

The syntax of the remove[] method is:

list.remove[element]

The remove[] method takes a single element as an argument and removes it from the list.
If the element doesn't exist, it throws ValueError: list.remove[x]: x not in list exception.

The remove[] doesn't return any value [returns None].

# animals list animals = ['cat', 'dog', 'rabbit', 'guinea pig']

# 'rabbit' is removed animals.remove['rabbit']

# Updated animals List print['Updated animals list: ', animals]

Output

Updated animals list: ['cat', 'dog', 'guinea pig']

If a list contains duplicate elements, the remove[] method only removes the first matching element.

# animals list animals = ['cat', 'dog', 'dog', 'guinea pig', 'dog']

# 'dog' is removed animals.remove['dog']

# Updated animals list print['Updated animals list: ', animals]

Output

Updated animals list: ['cat', 'dog', 'guinea pig', 'dog']

Here, only the first occurrence of element 'dog' is removed from the list.

# animals list animals = ['cat', 'dog', 'rabbit', 'guinea pig']

# Deleting 'fish' element animals.remove['fish']

# Updated animals List print['Updated animals list: ', animals]

Output

Traceback [most recent call last]: File ".. .. ..", line 5, in animal.remove['fish'] ValueError: list.remove[x]: x not in list

Here, we are getting an error because the animals list doesn't contain 'fish'.

If you need to delete elements based on the index [like the fourth element], you can use the pop[] method.
Also, you can use the Python del statement to remove items from the list.
