(Python Example for Citizen Data Scientist & Business Analyst)

 

Write a Python program to create a deque from an existing iterable object.

 

Sample Solution:

Python Code:


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))

Sample Output:

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'>
