(Watch out, dicts are no sequence types.) I recommend relying duck typing as long as it's feasible. I. e. if it can be subscripted like a dict, it is a dict. If this makes problems, use the type({}) approach. Regards, Björn -- BOFH excuse #56: Electricians made popcorn in the power supply -- http://mail.python.org/mailman/listinfo/python-list
