How to Remove an Element from a List in Python

​Python provides many ways to help us remove a specific element from a list. Using the built-in functions Remove() , pop() and clear() . We can also use the del keyword to remove elements from the list.

Method 1: Use the Remove() function

Items can be removed from the list using the built-in Remove() function but an error is raised if the item is not in the list. The Remove() function removes only one element at a time, the Remove() function removes only the selected element.

Note: The Remove() function removes only the first occurrence of the searched element.

Example:

# Create a list
List = [1, 2, 3, 4, 5, 6,7, 8, 9, 10]
print("original list:")
print (List)
# Remove items from the list
# Remove() using a function
List. remove(3)
List. remove(6)
print("\nThe list after removing two elements: ")
print(List)

The output will be:

original list:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
List after removing two items:
[1, 2, 4, 5, 7, 8, 9, 10]

Method 2: Use the pop() function

The pop() function can also be used to remove and return an item from the list, but by default it only removes the last item from the listundefined list, to remove an element from a specific position in the list, the index of the element is passed as an argument to the pop() function.

 Example:

 # Create a list
 List = [1, 2, 3, 4, 5, 6,7, 8, 9, 10]
 print("original list:")
 print (List)
 # Remove items from the list
 # pop() using a function
 List.pop(2)
 print("\nThe list after removing the element with index 2: ")
 print(List)

 The output will be:

 original list:
 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
 The list after removing the element with index 2:
 [1, 2, 4, 5, 6, 7, 8, 9, 10]

 Method 3: Use the clear() function

The clear() function removes all elements from the list. Clears the list completely and returns nothing. It requires no arguments and returns no exception if the list is already empty.

 Example:

 # Create a list
 List = [1, 2, 3, 4, 5, 6,7, 8, 9, 10]
 print("original list:")
 print (List)
 # Remove items from the list
 # clear() using a function
 List. clear()
 print("\nThe list after removing all its elements :")
 print(List)

 The output will be:

 original list:
 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
 List after removing all its elements:
 []
