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))
