Python Why don't nested functions work when multithreaded?

Question

Python

It is necessary that two subroutines work in parallel I
use multiprocessing

p1 = Process(target=monitor)
p2 = Process(target=bot)

These programs have plug-in libraries, inside which there are still connections.
When I run these files separately, everything works fine.
But when I run them in threads, the programs themselves work, but when it comes to functions from other nested libraries, it freezes and does not give an answer
. how to correct it?

Answer 1

For anything to work in multithreading, all this code must be specially adapted for multithreading, along with all the modules and libraries it uses, including extensions on these. If at least some of this is not thread-safe, then the whole code will not be thread-safe.
Use better multiprocessing.
