Paul Rubin wrote: Ethan Furman et...@stoneleaf.us writes: some_list = [1, 2] this, that = func(alist) At least, in 2.5.4 this works. :-) But that fails if there are fewer than two elements in the list. It's better to just make the logic either expect a list, or if it's implementing

Re: Is there a better way to code variable number of return arguments?

This is an interesting alternative. If one wants to generate everything and return it at one shot, the list approach is better, but there are situations where generating things incrementally is preferrable, e.g., because the caller doesn't know a priori how many things he wants. I will try
