I think what you're looking for here is an acknowledgement that evaluating the name "next" accomplishes nothing. That's not really something the Python interpreter should be looking at (hey, you might have good reason for doing that), but there are linters that can detect this kind of dead code. Some of them tie into programmer's editors, so you could get a nice little warning message right in the window where you're typing your code. Look into some of the top-end editors (free or commercial) and see what you think of them - they can save you no end of time. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
