Notice that you are asked to *return* a number not print it.
Also notice that the condition is an AND not an OR.

Notice that this return will throw you out of the function so
you don't process any more strings. You might like to look
at 'continue' as an alternative.

And here you print the result not return it.
So the return value from your function as is will be None or ''

But you are quite close to the solution.
