Hi! I would like to create a pretty big list of lists; a list 3,000,000 long, each entry containing 5 empty lists. My application will append data each of the 5 sublists, so they will be of varying lengths (so no arrays!).
Does anyone know the most efficient way to do this? I have tried: list = [[[],[],[],[],[]] for _ in xrange(3000000)] but its not soooo fast. Is there a way to do this without looping? David. -- http://mail.python.org/mailman/listinfo/python-list
