Just to be clear: you do _not_ want to use eval on the string. If you're not the one who created the string, it might wipe your hard drive or empty your bank account. If you _are_ the one who created the string, then generate the desired result instead. -- Grant -- https://mail.python.org/mailman/listinfo/python-list
