Using the clear() Function to Remove All Values in a List

In Python, the clear() method is used to remove all elements from a list, leaving it empty but still defined.

This method does not delete the list itself—only its contents.

Example Usage of clear() Function
my_list = [1, 2, 3, 4, 5] # Output: [1, 2, 3, 4, 5] print("my_list:", my_list) # Remove all elements from the list my_list.clear() # Output: [] print("my_list:", my_list)

In the code above, the clear() function is used to remove all elements from my_list.

After calling clear(), my_list becomes an empty list ([]), but the list object still exists in memory and can be reused.

The clear() method is useful when you need to quickly empty a large list or when you want to reuse a defined list.
