Run multiple python scripts concurrently

Question

How can I run multiple python scripts? At the moment I run one like so python script1.py.

I've tried python script1.py script2.py and that doesn't work: only the first script is run. Also, I've tried using a single file like this;

import script1 import script2  python script1.py python script2.py 

However this doesn't work either.

Answer 1

With Bash:

python script1.py & python script2.py & 

That's the entire script. It will run the two Python scripts at the same time.

Python could do the same thing itself but it would take a lot more typing and is a bad choice for the problem at hand.

I think it's possible though that you are taking the wrong approach to solving your problem, and I'd like to hear what you're getting at.

Answer 2

The simplest solution to run two Python processes concurrently is to run them from a bash file, and tell each process to go into the background with the & shell operator.

python script1.py & python script2.py & 

For a more controlled way to run many processes in parallel, look into the Supervisor project, or use the multiprocessing module to orchestrate from inside Python.
