Hey, AshFaden.
I’m not quite sure what python is, but I think most of what you want is obtainable without it. I think the most players you can have in a game of StarCraft at once without modding is eight (8) meaning that the most you have for equal teams is 4 players on each side, however I might be mistaken by this(couldn’t get the last 4 of the 12 player slots to work).
I made a post replying to someone with a similar question that might help you although I don’t mind giving you extra help if you’re still confused.

Hope this helps.
