Nobody said anything of the sort. I write stuff in python all the time.

Okay, here's a little example. Try to write a python program that can
return exit code 0 if /etc/resolve.conf exists, the catch being that
it has to return within 10ms on hardware 3 years old. The deal breaker
is the time of the python interpretor to startup, and the time to
interpret the file.

Now imagine you're trying to write a command-not-found implementation
that uses python to load yum. The Yum codebase is pretty huge, and by
the time the 50ms  "user needs results now" timer expires we're not
even at "loading metadata" let alone returning results.

Python is awesome for prototyping and for little scripts. It's just
not awesome at everything.
