Even assuming your figures to be 100% accurate, I don't think you can
accept that scaling. Are you claiming that every high school student
(a) continues to use Python forever, and (b) continues to use it at a
non-professional level? I find that highly unlikely.
I'm pretty dubious that these figures will correspond to the rest of
the world, where you can't expect that every single high school
student is using Python.
