I always thought of list comprehension as a fast way to just throw together a list, not as a way to "program" the list contents. IMHO, that should be done using explicit statements in the way Skip describes above. I would be completely satisfied with e.g. [0..10], [0..10:2] and [10..0]. -- Marc-Andre Lemburg ______________________________________________________________________ Business: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
