Just a suggestion

Hi, Excellent stuff, I just wanted to point out that you used "input" as a variable name, it's actually an inbuilt names reserved that perform an action, it let's you get input from a user. I know in this case your not likely to use it elsewhere and you can override the inbuilt names but it's not advised. You can tell a name is reserved usually because it changes color, in this color scheme it turns green.
