Multithreading with Python

What resources did you guys use to learn how to multi-thread your Python programs? I would like my simple selenium bot to be able to run multiple instances concurrently, but find the subject a bit intimidating (I'm in the early stages of learning OOP).

Thread moved.

Go is the best language right now for concurrency. It's concurrency features make python's look like a childs toy.

It compiles down to native code, and there's also a pretty good selenium webdriver for Go.
