Python 1.4 had it, and that's the earliest version of the documentation
that exists on the website.

Python 1.0.1 does include rangeobject, with a timestamp on rangeobject.h
of 1994-01-01.

Python 0.9.1 does not.

So it was added some time between the original alt.sources posting
(February 1991) and version 1.0 (January 1994). And one could argue that
1.0 was the first "real" release of the language.

And of course, you were always free to write:

i = 0
while i < 999999:
    i = i + 1
