What is the time complexity of queue operations in Python?

What is the time complexity of queue operations in Python?

In Python, the time complexity for queue operations using the collections.deque is O(1) for both enqueue and dequeue operations.

How does this compare to a list implementation?

Using a list for queue operations has a time complexity of O(n) for dequeue operations because it requires shifting elements.

Are there any other data structures I can use for queues?

Yes, you can also use the queue.Queue class, which is thread-safe and provides similar O(1) complexity for enqueue and dequeue.

What about the memory usage of these data structures?

collections.deque is more memory efficient for queues compared to lists, as it allocates memory in a way that minimizes overhead.
