There is one obvious way to do it, and that is the way you should do it. There is no excuse for doing it a clever way.

a = open("numbers.txt", "w")
for i in xrange(100):
    a.write("%d " % i)
d.close()

Lazy execution gives you a serious benefit: It allows you to pass a sequence to another piece of code without having to hold the entire thing in memory. It is for the creation of efficient sequences as data types.

In this case, you do not want lazy execution. You want execution. You can just ... execute. With a for loop.
