Hi Cristian,

as far as I can see, the tutorial only contains an informal description of
range(), which covers the basic use.  Corner cases like this should be
covered by the library docs, which you get to when you click the range()
link.

Unfortunately, that text doesn't fully specify this case either, although
the example code shows both range(0) and range(1, 0) being empty.

So I think that the range() docs should be amended.  In Python 3, the text
is much clearer: https://docs.python.org/3/library/stdtypes.html#range

If you'd like the tutorial text to change as well, can you tell us more
specifically where?

cheers,
Georg
