That would be easy enough (look up range in the Python docs) but I'm not
sure what you want to do is a good idea.

What happens if you present a range from 1 to 12 and while the user is
thinking about it someone else buys half a dozen?

Personally, I would be assuming orders will be un-satisfied and
re-design to cater for that gracefully. Perhaps you really need a
back-ordering system?
