How can I handle errors in multi-threaded Python applications?

In multi-threaded Python applications, you can handle errors using try-except blocks within each thread. This allows you to catch exceptions locally.

What if I want to log errors from all threads to a single log file?

You can use a logging library like logging in Python. Set up a logger that writes to a file and ensure each thread uses this logger to log errors.

Is there a way to propagate exceptions from threads back to the main thread?

Yes, you can use a queue to send exceptions from worker threads back to the main thread. The main thread can then handle these exceptions as needed.

Can you give me an example of using a queue for this?

Sure! You can create a queue.Queue instance, and each thread can put its exception into the queue. The main thread can then retrieve and handle these exceptions.
