What are some use cases for queues in Python?

Queues are useful for managing tasks in a first-in, first-out manner. Common use cases include task scheduling, handling asynchronous requests, and managing data streams.

Can you give me an example of a task scheduling use case?

Sure! You can use a queue to manage background tasks in a web application, like sending emails or processing images, ensuring they are handled in the order they were received.

What libraries can I use to implement queues in Python?

You can use the built-in queue module for simple use cases, or libraries like Celery for distributed task queues and RQ for Redis-based queues.

How do I implement a basic queue using the queue module?

You can create a queue using from queue import Queue, then use put() to add items and get() to retrieve them. Here's a simple example:

from queue import Queue
q = Queue()
q.put('task1')
task = q.get()
print(task)  # Outputs: task1
