What inputs are you testing?  What output do you get?

You were doing fine, but summarized a little bit too much at the end.
Unlikely as it might seem, those details might matter, or at the very
least may help us discount certain possibilities.  Can you show us how
you're testing it?


(One of those "silly" possibilities: the function you're calling might
not be the function you've defined.  You call your function
shut_down(), but given that underscore, maybe you've defined a
function "shutdown" by accident?  It's those sort of niggling details
we need to discount; without seeing how you're doing your testing, we
have to leave that distant possibility open.)
