Python does the same thing with range:

 >>> range(1,10)
 [1, 2, 3, 4, 5, 6, 7, 8, 9]

Leaving out the starting value starts at zero:

 >>> range(10)
 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Which is like dotimes:

 [1]> (dotimes (i 10) (format t "~d" i))
 0123456789
 NIL

There's an implied "less than the supplied high value" in all cases.
