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

If you want to call an external program (especially one not written in Python) use subprocess.

If you want to call a Python function in a subprocess, use multiprocessing.

(If the program is written in Python, but is also importable, then I would try to call its functions using multiprocessing, rather than calling it externally through subprocess.)
