How can I debug parallel code in Python?

How can I debug parallel code in Python?

Debugging parallel code can be tricky. You can use tools like pdb for single-threaded debugging, but for parallel code, consider using multiprocessing's logging features or concurrent.futures with ThreadPoolExecutor.

What if I want to see the output of each thread?

You can redirect the output of each thread to a log file or use a thread-safe queue to collect results from each thread.

Are there any specific libraries that can help with debugging?

Yes, libraries like py-spy and line_profiler can help you analyze performance and identify bottlenecks in your parallel code.

Can I use print statements for debugging?

While you can use print statements, it's better to use logging for thread safety and to avoid mixed outputs from different threads.
