How to Reset a List in Python?

To reset a list in Python and remove all existing elements, you have a few options:

1. Reassignment: You can reset the list by reassigning it with an empty list ([]). This effectively replaces the old list with a new, empty list. For example:

my_list = [1, 2, 3, 4, 5]

# Reset the list by reassigning it with an empty list
my_list = []

# Now the list is reset and contains no elements

In this example, the variable my_list is initially assigned a list of elements. To reset the list, it is reassigned with an empty list, effectively removing all existing elements.

2. Clearing the list: Another way to reset a list is by using the clear() method. The clear() method removes all elements from the list in-place, leaving an empty list. Here’s an example:

my_list = [1, 2, 3, 4, 5]

# Reset the list by clearing it
my_list.clear()

# Now the list is reset and contains no elements

In this example, the clear() method is called on the list, removing all elements and leaving an empty list.

Choose the method that best fits your needs. Reassignment with an empty list creates a new list object, while the clear() method modifies the existing list in-place.
