Answers To 180+ Interview Questions On Python Multiprocessing

How well do you know Python multiprocessing?

The multiprocessing module provides process-based concurrency in Python and few developers know about it, let alone, how to use it well.

The main reason is that it is widely thought that Python does not fully support concurrency.

This is false.

In fact, processes provide the best path to full parallelism in Python for CPU-bound tasks.

  • Do you know how to start a new process?
  • Do you know how to use mutex locks with Python processes?
  • Do you know how to use a manager or a pool?
