In this tutorial, we will learn about the Python List clear() method with the help of examples.
The clear() method removes all items from the list.
Example
prime_numbers = [2, 3, 5, 7, 9, 11]
# remove all elements
prime_numbers.clear()
# Updated prime_numbers List
print('List after clear():', prime_numbers)
# Output: List after clear(): []
1. Syntax of List clear()
The syntax of clear() method is:
list.clear()
2. clear() Parameters
The clear() method doesn’t take any parameters.
3. Return Value from clear()
The clear() method only empties the given list. It doesn’t return any value.
4. Example 1: Working of clear() method
# Defining a list
list = [{1, 2}, ('a'), ['1.1', '2.2']]
# clearing the list
list.clear()
print('List:', list)
Output
List: []
Note: If you are using Python 2 or Python 3.2 and below, you cannot use the clear() method. You can use the del operator instead.
5. Example 2: Emptying the List Using del
# Defining a list
list = [{1, 2}, ('a'), ['1.1', '2.2']]
# clearing the list
del list[:]
print('List:', list)
Output
List: []
