I'm trying to generate a list of values where each value is dependent on the previous value in the list and this bit of code needs to be repeatedly so I'd like it to be fast. It doesn't seem that comprehensions will work as each pass needs to take the result of the previous pass as it's argument. map() doesn't seem likely. filter() or reduce() seem workable but not very clean. Is there a good way to do this? About the best I can get is this:
l = [ func ( start ) ] f = lambda a: func ( l[-1] ) or a filter ( f, range ( big_number, -1, -1 ) ) I guess I'm looking for something more like: l = do ( lambda a: func ( a ), big_number, start ) Thanks, Michael McGlothlin -- http://mail.python.org/mailman/listinfo/python-list
