[Tutor] How to handle exceptions raised inside a function?

Please take a look at 2 functions I just wrote to calculate the
harmonic and geometric means of lists of positive numbers:

Both Hlist and Glist must contain only positive numbers, so I really
need to test for this inside each function. But is there a good way to
do this? What should the functions return should a non-positive number
be detected? Is there a conventional Pythonic way to do this?
