Hello. We are sorry but we cannot help you. This mailing list is to work on developing Python (adding new features to Python itself and fixing bugs); if you're having problems learning, understanding or using Python, please find another forum. Probably python-list/comp.lang.python mailing list/news group is the best place; there are Python developers who participate in it; you may get a faster, and probably more complete, answer there. See http://www.python.org/community/ for other lists/news groups/fora. Thank you for understanding.
