The Python clear() method is used to clear all elements from the list.

How to clear elements from List in Python:

the clear() method can be applied on a python list to remove all elements, it doesn’t take any values as parameters and doesn’t return (None) anything.

1. list.clear()

In the following example, I am going to create a list first and remove all elements at a once.

if __name__ == '__main__':
    fruits = ['Apple','Banana','Gua','Pineapple','Mango']
    # Before clearing the list
    print(fruits)
    fruits.clear()
    # After clearing the list
    print(fruits)

Output:

['Apple', 'Banana', 'Gua', 'Pineapple', 'Mango']
[]

2. del:

del is a keyword in python, which is used to delete objects, lists or part of lists

if __name__ == '__main__':
    fruits = ['Apple','Banana','Gua','Pineapple','Mango']
    # Before clearing the list
    print(fruits)
    del fruits[:]
    # After clearing the list
    print(fruits)

Output:

['Apple', 'Banana', 'Gua', 'Pineapple', 'Mango']
[]

3. *=0

A python list can be empty by multiplying with 0 like below.

if __name__ == '__main__':
    fruits = ['Apple','Banana','Gua','Pineapple','Mango']
    # Before clearing the list
    print(fruits)

    # After clearing the list

    fruits *=0
    # After clearing the list
    print(fruits)

Output:

['Apple', 'Banana', 'Gua', 'Pineapple', 'Mango']
[]
