Popping an element from the list

The pop() method enables removing an element from a specified position and return it:

    >>> index_list = [1, 2, 3, 4, 5, 6, 7]
    >>> index_list.pop(3)
    4
    >>> index_list
    [1, 2, 3, 5, 6, 7]

In this example, the index_list list consists of numbers between 1 and 7. When the third element is popped by passing the index position (3) as an argument, the number 4 is removed from the list and returned.

If no arguments are provided for the index position, the last element is popped and returned:

    >>> index_list.pop()
    7
    >>> index_list
    [1, 2, 3, 5, 6]

In this example, the last element (7) was popped and returned.
