We're all volunteers (and it's now 7:30AM Saturday and I've been up all night, so this post quite probably doesn't carry the hallmarks of intelligence). To be more strictly correct, we are members of a community - people helping people. Far as I know, there's not one person here who has never asked a question. I tend to join a mailing list to ask one or more questions, and hang around answering them long after my personal needs are satisfied, kinda like seeding back a torrent after you've downloaded it. We answer questions for a variety of reasons. Partly, because this is one of the best forms of help that the Python community can offer, which means that supporting Python in this way strengthens the language. Partly, because our names are connected to our posts, and we are seen to be helpful people (and, since the list/newsgroup is archived on the web, potential employers who search the web for our names will see us being helpful and knowledgeable). Partly, because we're repaying the community for the benefits we've gained from it. Partly, because in answering questions, we ourselves learn. And there are other reasons too. > 2) sorry for the dutch names :) No probs; as was said in several follow-ups, those are well-chosen names. > b) the problem i originally described in my first post was not resolved, by > means of elimination i could conclude that the problem situates itself in > this lines : > > c = list(self.frame.axis) > c[2] -= 0.1 > c = tuple(c) > c = self.frame.axis This code is looking quite messy, here. But the most obvious problem is that you're setting up 'c' to be the modified axis, and then... overwriting c with the old axis. Try doing the assignment the other way in the last line: self.frame.axis = c Alternatively, you could do the whole thing more cleanly by unpacking and then repacking the tuple: (x, y, z) = self.frame.axis self.frame.axis = (x, y, z-0.1) Two lines that do the job of the above four. Note that the parentheses are optional here; they look nice since axis is holding coordinates, but Python doesn't care. Hope that helps! ChrisA -- http://mail.python.org/mailman/listinfo/python-list
