What makes you think so? Did you try? What error did you get?
And what version of python were you using?

FWIW I tried xrange with 10**16 and it seemed to work,
albeit it took a long time.(about 15min for each 10**10
iterations)) I gave up waiting after it reached 10**11...

But if you are sure that doesn't work you can always use
a while loop instead:

n = 0
while n < 10**15
    # do something
    n += 1
