Python was originally designed for adult professionals with some coding experience, is not all that beginner friendly in the "never programmed ever" sense. Some curricula use toy languages as stepping stones, others start with Python as maybe the easiest of the real world languages (because of REPL etc.). http://xkcd.com/353/ Here's some code for testing a keepmoving() framework, such as Brian was proposing. Note my caveat, as well as my use of a generator for a generic controller (with flagged changing syntax).** Anyway, enough from my corner. Back at ya next week!
