The match object has an attribute called "groupdict", so you can get the found named groups using match.groupdict.keys. I can't remember what happens to unnamed groups (I prefer to name every group I want), but ISTR that there is a list of capture groups in which the indexes are the capture groups number (i.e. what you'd use to backreference them). > Can I make the match object to return default values for named > groups, even if no match was produced? A lazy solution I've used was to write a default dict, then update it with the groupdict. I doubt that's all that efficient, but the defaults were constant strings and the program was network-bound anyway. -- https://mail.python.org/mailman/listinfo/python-list
