What's so complex about a nested loop? And why are you saying that it is "more complex" than the Original Poster's solution, which also had a nested loop, plus a pointless list comprehension? > though I would > personally do it as: > > a = [ [1,2,3,4], [5,6,7,8] ] > from itertools import chain > for i in chain.from_iterable(a): > print i > > so it won't choke when 'a' is an infinite stream of iterables. Neither will a nested for-loop. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
