Those are tuples, not lists. Are you trying to create a list of tuples from a, b, and c? If so, then zip does what you want: >>> d = list(zip(a, b, c)) >>> d [(1, 'Red', 'a'), (2, 'Green', 'b'), (3, 'Blue', 'c')] Or do you want all those elements merged into a single list? >>> d = list(sum(zip(a, b, c), ())) >>> d [1, 'Red', 'a', 2, 'Green', 'b', 3, 'Blue', 'c'] -- https://mail.python.org/mailman/listinfo/python-list
