How to run python script from python with different interpreter version?

Question

How to run my script with one version of python from script with another version of python? Also, is there a way to catch all outputs of my script and print it?

Answer 1

So you want to theoretically run say a script with python2 from a script running with python3? (Or something like that, I'm not really sure) If so I would use subprocess. You can find more information on that https://docs.python.org/2/library/subprocess.html and How do I execute a program from python? os.system fails due to spaces in path .

#my python3 script
import subprocess
subprocess.call(["python2", "python2scipt.py"])
