It helps if you show all of your code and the complete traceback.
Having said that look carefully at your code. You've a function called
pounds that's trying to print something called pounds and return pounds.
The pounds function calls the weight function which sets something
called pounds but does nothing with it. Within the pounds function you
set h_book and p_book to None as this will be the default returned by
weight as you haven't specified a return statement within weight. That
doesn't matter as you don't use h_book and p_book anyway, at least not
in the code that you've shown. Got it?
I'll leave you to sort out your code. If you still have problems please
come back and ask, my barks's much worse than my bite :)
