Remove element from list Python

In this post, you will see how to remove the element from a list in Python.

A list is a sequence of indexed and ordered values, like an array. It is mutable, means we can change the order of elements in a list. It contains a list of any type of data objects with comma separated and enclosed within an square bracket. Each element of list has an index, starting with 0 , 1 and so on. In the development process, we may come to the situation in which we need to decrease the size of the list by removing the elements of the list.

In Python, there are numerous methods available on the list data type that help you to eliminate an element from a given list.



List pop()

The pop() method removes the element at the specified index position. The syntax of the pop() method is -

list.pop(index)

Here, the index is optional which specifies the position of the element you want to remove. By default, it removes the last element from the list. Here is the example -

list_elems = ['bread', 'cookies', 'chocolate', 'tea', 'cake']

# Remove last element from list
list_elems.pop()
print(list_elems)

# Remove second element from list
list_elems.pop(1)
print(list_elems)
Output of the above code -
['bread', 'cookies', 'chocolate', 'tea']
['bread', 'chocolate', 'tea']




del statement

In Python, del is a keyword. We can use this del keyword to delete any objects, like - lists, variables, user-defined objects, items within lists, dictionaries and so on. The syntax of the del is -

del obj_name

To delete the last element from a list, apply the negative indexing to the list, and offer it to the del keyword to erase it.

list_elems = ['cat', 'dog', 'fox', 'rabbit', 'elephant']

# Remove last element from list
del list_elems[-1]

print(list_elems)

# Remove third element from list
del list_elems[2]

print(list_elems)
Output of the above code -
['cat', 'dog', 'fox', 'rabbit']
['cat', 'dog', 'rabbit']




remove() method

In Python, the remove() method removes the first occurrence of the element with the specified value. The syntax of the remove is -

list.remove(element)

Here, the element is the required parameter which accepts the item value as argument. This can be of any type list, string, number etc.

list_elems = [43, 45, 89, 29, 30, 63, 10]

# Remove element from list
list_elems.remove(89)
print(list_elems)

# Remove element from list
list_elems.remove(30)
print(list_elems)
Output of the above code -
[43, 45, 29, 30, 63, 10]
[43, 45, 29, 63, 10]


clear() method

Python provides clear() method to remove all the elements from the list. It returns empty list after operation.

list_elems = [43, 45, 89, 29, 30, 63, 10]

# clear list
list_elems.clear()

print(list_elems)
Output of the above code -
[]
