Python subprocess/Popen with a modified environment

Question

I believe that running an external command with a slightly modified environment is a very common case. That\'s how I tend to do it:

import subprocess, os
my_         


        

Answer 1

The env parameter accepts a dictionary. You can simply take os.environ, add a key (your desired variable) (to a copy of the dict if you must) to that and use it as a parameter to Popen.
