What is the difference between multiprocessing and subprocess?

Question

My work should use parallel techniques, and I a new user of python. So I wonder if you could share some material about the python multiprocessing and subp

Answer 1

Subprocess spawns new processes, but aside from stdin/stdout and whatever other APIs the other program may implement you have no means to communicate with them. Its main purpose is to launch processes that are completely separate from your own program.

Multiprocessing also spawns new processes, but they run your code, and are designed to communicate with each other. You use it to divide tasks within your own program across multiple CPU cores.
