I'm trying to use python to set environment variables that will persist in Pythons parent environment, even after python exits back to the shell, but will not persist once the parent shell is closed. Opening a new shell should require that the python script be run again in order to set the environment correctly.
Based off the recommendations from this post, I'm trying to do this using the win32com python library. Unfortunately, I have very little experience with the win32 api.
Basically, I need a way to get a handle to the current environment, and set environment variables in such a way that they will persist in python's parent environment, but will not persist after the parent environment exits.
It is impossible to change the environment of the parent, by design. The best you can do is have your program emit commands that alter the environment, and then the caller of your program needs to eval the output of your command.
