What are the different threading models in Python?

In Python, the main threading models are the Global Interpreter Lock (GIL), threading module, and multiprocessing module.

Can you explain the Global Interpreter Lock (GIL)?

The GIL is a mutex that protects access to Python objects, preventing multiple threads from executing Python bytecodes simultaneously.

How does the threading module work?

The threading module allows you to create and manage threads, enabling concurrent execution of code within a single process.

When should I use multiprocessing instead of threading?

Use multiprocessing when you need to bypass the GIL for CPU-bound tasks, as it allows true parallelism by using separate memory spaces.
