The pop() method removes and returns the element at the specified index in a list. If no index is specified, it removes and returns the last element in the list.
numbers = [1, 2, 3, 4, 5]
removed_number = numbers.pop(2)
print('Removed number:', removed_number)
print('Updated list:', numbers)If the index provided is out of range, IndexError is raised.
letters = ['a', 'b', 'c']
removed_letter = letters.pop(5)
print('Removed letter:', removed_letter)
print('Updated list:', letters)Using pop() without an index removes and returns the last element in the list.
