How can I debug my Python threading code?

I'm having trouble with my Python threading code. It seems to hang sometimes. How can I debug it?

Debugging threading issues can be tricky. First, ensure you're using locks properly to avoid race conditions. Can you share your code?

Sure! Here’s a snippet:

import threading

lock = threading.Lock()

def thread_function():
    lock.acquire()
    # some critical section code
    lock.release()

It hangs sometimes when multiple threads try to access the critical section.

It looks like you're using locks correctly, but make sure that every acquire() has a corresponding release(). If a thread fails before releasing the lock, it can cause a deadlock. Have you checked for exceptions in your threads?

I haven't checked for exceptions. How can I do that?

You can wrap your critical section code in a try-except block. This way, if an exception occurs, you can ensure the lock is released. Would you like an example?
