Multithreading and multiprocessing allow computers to multitask and perform various tasks at the same time.
These concepts also help provide insane speedups to Python code.

In this video, we explore the multiprocessing module in Python and go over the main features.

We look at how multiprocessing can speed up a CPU bound application, we also look at how to achieve interprocess communication through Queues and how to use shared variables using Values. Finally, we uncover the importance of locks in concurrent and parallel tasks touching upon race conditions and how locks help prevent them. All this is shown using practical, real life examples!
