What are some real-world examples of threading in Python?

Threading in Python is often used in applications like web servers, data processing, and GUI applications. For instance, a web server can handle multiple requests simultaneously using threads.

Can you give me a specific example of a web server using threading?

Sure! A popular example is Flask, a web framework that can be run with a threaded server. This allows it to handle multiple client requests at the same time.

What about data processing? How is threading used there?

In data processing, threading can be used to parallelize tasks like downloading files or processing large datasets. For example, using the concurrent.futures module allows you to run multiple data processing tasks concurrently.

Are there any downsides to using threading in Python?

Yes, one downside is the Global Interpreter Lock (GIL) in CPython, which can limit the performance benefits of threading for CPU-bound tasks. It's often better to use multiprocessing for those cases.
