I came up with a pretty good solution using the re module and the locale module... My script validates when i execute it on my desktop pc (Python 3.3.0, win 7) on IDLE but when i execute it in the Checkio compiler (which i chose it to be Python 3.3.0) it gives me the following error:ImportError: locale <module>, 2** ErrUchIsDown and the Check results panel keeps loading for ever... Is it a bug, locale module is supposed to be valid in Python 3.3.0???
