What is xrange?

[Billy Mays]

Is xrange not a generator?  I know it doesn't return a tuple or list, so 
what exactly is it?  Y doesn't ever complete, but x does.

x = (i for i in range(10))
y = xrange(10)
print "===X==="
while True:
    for i in x:
        print i
        break
    else:
        break

print "===Y==="
while True:
    for i in y:
        print i
        break
    else:
        break
