Thanks, Steve. So, global is only to within a module (I was afraid of that). Those words flashed by me when I was reading it but since the word "module" didn't translate to "file" in my C mind, I didn't catch that.
In that case, you are correct that I have to do an import of file1 in file2. Not that this is not real code, I am still trying to learn the ins and outs of Python by writing some silly code - but will be important to help me understand how I would write the real code. Regarding the question of not placing everything in one module, I wouldn't think that that's how I would do it. I might get ambitous later and write code for a larger project. In that case, I will need to know more about scoping across multiple modules. So, this helps me understand what to do. Thanks again.
