Does Python have real multithreading?

Both multithreading and multiprocessing allow Python code to run concurrently. Only multiprocessing will allow your code to be truly parallel. However, if your code is IO-heavy (like HTTP requests), then multithreading will still probably speed up your code.

Why is multithreading bad in Python?

Python threading allows you to have different parts of your program run concurrently and can simplify your design. If you've got some experience in Python and want to speed up your program using threads, then this tutorial is for you!
