Recursively create a file

Sorry Ofnuts but I can't see how that tell me why the open() line I wrote won't work in my code

Maybe not, but you have the exact three lines of code repeated over and over again, which is a problem functions can fix. ...and that'll make it easier to read, so random people like us can just glance at your code to see if there's an issue, instead of intently studying it for minor changes from block to block.
