Python 1.4 (that's 1996) had xrange, but I don't know when it was added.

https://docs.python.org/release/1.4/lib/node26.html#SECTION00330000000000000000


The oldest version I have access to is the *extremely* primitive 0.9. Not
surprisingly, it doesn't have xrange -- but it lacks a lot of things,
including globals(), map(), named exceptions, "" strings ('' is okay),
exponentiation, and more.
