Sorry, but there aren't many books about multithreading in Python. And there is a reason for it:
Python, just as Ruby, can't REALLY handle multithreading.
Yes, you have a Thread interface, and you can use it. And it will, create a thread parallel to the main thread... BUT in Python and Ruby, there is a GIL (Global Interpreter Lock). Which means that every thread running will block the interpreter, so never two threads access to the same object at the same time. It means that while one thread is executed, the other one will be waiting for the lock to be released. So if you do some tests with multithreading in python, you could get surprised about how the performance keeps being the same, or even goes down a little bit because of the overheat of handling multiple threads.

But (and I am sorry for this), sadly, I am going to end this post with the question that people usually makes in this case:
— If you want to use parallelism, are you sure that Python is the right tool for that job?
If there are no other options than using python, then the book that I shared is a good alternative.
Oh, I forgot to mention this blog post, and looks like there is no option to edit my previous answer:
