Communicating between Autohotkey and python

Inter-process communication would be capable of sending the information while the Python script is already running.

You could also use TCP/IP Network communication (like in the post below), but that probably wouldn't be quite as slick as using IPC.

The way you got it working is the easiest, and probably best, method of accomplishing what you want.

Communication between applications can be done with more methods then you probably can imagine, but as long as it doesn't have to be realtime you can call your programs with arguments, as it is easy and reliable.
