Write a Python program to create a deque from an existing iterable object.
import collections even_nums = (2, 4, 6) print("Original tuple:") print(even_nums) print(type(even_nums)) even_nums_deque = collections.deque(even_nums) print("\nOriginal deque:") print(even_nums_deque) even_nums_deque.append(8) even_nums_deque.append(10) even_nums_deque.append(12) even_nums_deque.appendleft(2) print("New deque from an existing iterable object:") print(even_nums_deque) print(type(even_nums_deque))
Original tuple: (2, 4, 6) <class 'tuple'> Original deque: deque([2, 4, 6]) New deque from an existing iterable object: deque([2, 2, 4, 6, 8, 10, 12]) <class 'collections.deque'>
