no! For one thing, it still prints out an opening '[' before 1. Second of all, relying on the structure of the string representation of an array is just silly. Perhaps:

    print "\n".join(map(str, range(1,1001)))

or

    print "\n".join(str(i) for i in range(1,1001))

Heh, I forgot about join but that for is still a loop right? :)

Or else you could just:

    for i in range(1,1000):
        print i

Plus relying on the string representation of a list isn't silly it as it doesn't change. I just didn't know if range would meet the criteria or not.
