If you select File => New and then File => Save as, the default will be to make it a .py file if you add no other extension.
I have used idle before, but never set it up. my problem is actually getting a py file to work with. I don't actually know how to make one and it isn't an option when using save as on a text file. (only text file and all files(?) are put as options) I've attempted to open the py files already in the python folder but when selecting edit with idle I get prompted to pick what to open the file with and then if I click python nothing happens.
what am I missing?
