One suggestion I would have is keep the return type of fizzbuzz consistent. So I would probably do a return str(n) to ensure it is always a string. And in python I would follow snake_case with my variables so multiple_of_3 would be the preferred format.
Your solution looks good and I think it it correct, well done :)
lol, snake case for python. I get it! =D
I kinda wonder about these traditions of code styles and methods. It would be cool to tell a story about the history of traditions like "hello world" and such.
Thank you for the feedback. I'm come from Java. Automatically coded in it's coding style. lols
