Dynamically changing a variable inside a Python program

Question

I want to be able to dynamically change the value of a variable of a Python program outside of the program from another Python program. I have this function:

def main():
    PATH = 'path/to/file'

Is there a way to edit this variable from another Python program? The only way I can think of is sharing a text file between the two files, one inputs into it, one extracts from it.

Hmm no I haven't heard of that. I'll look into that, thanks. — KSHMR

A similar use case to the shared text file would be a database. — Lix

If you simply want to pass a path to some file to another program, maybe the easiest thing to do is to have the function accept that path as an argument? def main(path='/default/path'): ... — msvalkon

You indeed need to make configuration file. You can write some kind of parser for your .py file, search for desired string and edit it, but that's something I would not recommend you to do (take a look at this question).
For 'text file' solution take a look at ConfigParser
