Yeah, I came up with something similar, but it was so opaque I fell back to the more readable version I had above. With only the two variables to increment in this case, the overhead of duplicating code doesn't seem as worth it as it might be if there were umpteen counters being returned as a tuple and umpteen corresponding variables being updated (at which point, it might make more sense to switch to another data structure like a dict). Ah well. Glad to see at least I'm not the only one stymied by trying to make it more pythonic while at least keeping it readable. -tkc -- http://mail.python.org/mailman/listinfo/python-list
