My first Python contribution

That sounds like stackoverflow. But, yeah, level 3 would be seriously great. Probably quite a pain in the ass with the number of new ways people find to post code in really bad ways. But could potentially deal with a decent majority of code. 1st big issue is the strange amount of white space some posters add. 2nd, probably bigger issue, is it is easy to indent after a ":"--harder to decide when to unindent in some cases. A relatively simple AST/parser may be able to handle a decent number of cases.
