Python List remove() (2024)

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

Example

# create a listprime_numbers = [2, 3, 5, 7, 9, 11]# remove 9 from the listprime_numbers.remove(9)
# Updated prime_numbers Listprint('Updated List: ', prime_numbers)# Output: Updated List: [2, 3, 5, 7, 11]

Syntax of List remove()

The syntax of the remove() method is:

list.remove(element)

remove() Parameters

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.

Return Value from remove()

The remove() doesn't return any value (returns None).

Example 1: Remove element from the list

# animals listanimals = ['cat', 'dog', 'rabbit', 'guinea pig']# 'rabbit' is removedanimals.remove('rabbit')

# Updated animals Listprint('Updated animals list: ', animals)

Output

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

Example 2: remove() method on a list having duplicate elements

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

# animals listanimals = ['cat', 'dog', 'dog', 'guinea pig', 'dog']# 'dog' is removedanimals.remove('dog')
# Updated animals listprint('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.

Example 3: Deleting element that doesn't exist

# animals listanimals = ['cat', 'dog', 'rabbit', 'guinea pig']# Deleting 'fish' elementanimals.remove('fish')
# Updated animals Listprint('Updated animals list: ', animals)

Output

Traceback (most recent call last): File ".. .. ..", line 5, in <module> 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'.
