What are some examples of using deque in Python?

Can you give me some examples of how to use deque in Python?

Sure! A deque, or double-ended queue, allows you to add or remove elements from both ends efficiently. Here's a simple example:

That sounds interesting! Can you show me how to append and pop elements?

Absolutely! You can use append() to add elements to the right and appendleft() to add to the left. To remove elements, use pop() for the right and popleft() for the left.

Can you provide a code snippet for that?

Certainly! Here's a quick example:

from collections import deque

my_deque = deque()
my_deque.append(1)  # Add to the right
my_deque.appendleft(2)  # Add to the left
print(my_deque)  # Output: deque([2, 1])
my_deque.pop()  # Remove from the right
print(my_deque)  # Output: deque([2])
