Developers often consider multithreading to be a very complex topic. While this statement is totally true, Python provides high-level classes and functions that greatly help in using threads. CPython has some inconvenient implementation details that make threads less effective than in other programming languages like C or Java. But that doesn't mean that they are completely useless in Python.

There is still quite a large range of problems that can be solved effectively and conveniently with Python threads.

In this section, we will discuss those limitations of multithreading in CPython, as well as the common concurrent problems for which Python threads are still a viable solution.

What is multithreading?

Thread is short for a thread of execution. A programmer can split their work into threads that run simultaneously. Threads are still bound to the parent process and can easily communicate because they share the same memory context. The execution...
