Okay but very limited. – pythoni3.3 Review

This is a pretty good implementation of Python 3.3 but it appears that it doesn't support file handling at all. If that's a restriction on all aps, it ought to come with a disclaimer. It doesn't appear to support the isdigit() function, either, which may be an oversight, but with a little experience, you can write your own.
