How to empty a list in Python

We have seen how to take inputs to a list. Now we will see how to empty a list in Python. There are many ways for doing this. Let’s go through every method.

Using clear()

This built-in function empty the list completely.

li = [4, 34, 24, 5, 11]
print(li)

li.clear()
print(li)

Output:

[4, 34, 24, 5, 11]
[]

Using del()

The del() function selectively remove items at a given index or can used to remove all the elements, making the list empty.

li = ['a', 'e', 'i', 'o', 'b', 'u']
print(li)

#deleting one element at a specified index from the list
del li[4]
print(li)

#removing all the elements
del li[:]
print(li)

Output:

['a', 'e', 'i', 'o', 'b', 'u']
['a', 'e', 'i', 'o', 'u']
[]
