I'm glad you liked the link, but you haven't followed its advice :-) Also, pointing us to a pastebin is not helpful. Please use a user-agent that won't mangle your code so you can post code *here*. It's important that it be here, so that your post is self-contained and doesn't rely on some external URL to make sense years later. For the code itself, please make a short, self-contained, complete example (preferably conforming to PEP 8 so your lines fit within normal line length limits), and post it here for discussion. -- \ “Creativity can be a social contribution, but only in so far as | `\ society is free to use the results.” —Richard Stallman | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
