Looks like a bug in the tutorial! In Python 3 you cannot just print a range
it is now a generator. Notice that in the tutorial the range() calls are
not
shown at the >>> prompt.
They are not valid commands, the tutorial is just illustrating the expected
output from range for those values!
To see them you need to explicitly convert it to a list:
>>> list( range(0, 10, 3) )
[0, 3, 6, 9]
>>> list( range(-10, -100, -30) )
[-10, -40, -70]
