How do I run a python file in a different directory from another python file?

Question

During the course of my python program, I have generated the following string

"D:\something_else.py"

Lets say there are other resources in D: that something_else.py requires.

How would I go about running something_else.py from my code, which let's say is being run from C:\Users\Someone\Desktop?

Right now I'm using the following:

from subprocess import call 
call(["python",pythloc])

This gives me an error as it's able to find only something_else.py and is unable to find the other resources that something_else.py needs which are in the same folder as something_else.py

Answer 1

Besides the fact that you need to be careful with "\" and instead of :

   locationDir="D:\something_else.py"

prepend your string with r:

   locationDir=r"D:\something_else.py"

you can simply set the PYTHONPATH environment variable to point to the directory in which sit the other modules.
