When I programmed Factory512 all of the code was in one long file (1897 lines in fact) which meant that it took a while to scroll through. When I started my next game I did the same but by the time it was over 3000 lines I started to wonder if there was was a better way to deal with lots of code. Daddy looked it up and told me about modules. Modules allow you to have code in separate files that all run together. You just have to import the module at the start of the larger programme and then you can treat it like function (Except that that you must go into another file to see it). And it gets compiled too!(Compiled python runs faster) Yay!
