Answer 1

CPython (the classic and prevalent implementation of Python) can't have more than one thread executing Python bytecode at the same time. This means compute-bound programs will only use one core. I/O operations and computing happening inside C extensions (such as numpy) can operate simultaneously.

Other implementation of Python (such as Jython or PyPy) may behave differently, I'm less clear on their details.

The usual recommendation is to use many processes rather than many threads.
