Retrieving the return value of a Python script

Question

I have an external C# program which executes a Python script using the Process class.

My script returns a numerical code and I want to retrieve it from my C# program. Is this possible?

The problem is, I'm getting the return code of python.exe instead of the code returned from my script. (For example, 3.)

Answer 1

The interpreter does not return the value at the top of Python's stack, unless you do this:

if __name__ == "__main__":
    sys.exit(main())

or if you make a call to sys.exit elsewhere.

Here's a lot more documentation on this issue.
