Example of List clear()
Suppose we have a list of numbers, and we want to delete all elements from this list. For that, we will call the clear() method of List. For example,

# remove all elements from list
listOfNumbers.clear()
print(listOfNumbers)
print('Size of List is : ', len(listOfNumbers))
listOfNumbers = [22, 11, 33, 44, 11, 55, 11, 88, 77]
# remove all elements from list
listOfNumbers.clear()
print(listOfNumbers)
print('Size of List is : ', len(listOfNumbers))
Output:
Size of List is : 0
[] Size of List is : 0
It deleted all the elements from list, and size of list is now zero.
