I played around with a few things and this works but was wondering if there was a better way to do this. My first thought was list comprehension but could not get a figure out the syntax.
tag23gr is a list of lists each with two items. g23tag is an empty dictionary when I run the for loop below. When is is complete each key is a graphic name who's values are a list of tags. for item in tag23gr: ... value, key = tuple(item) ... if(g23tag.get(key)): ... g23tag[key].append(value) ... else: ... g23tag[key] = [value] -- http://mail.python.org/mailman/listinfo/python-list
