[Tutor] function signatures for callbacks

I have a piece of code that wants a callback from a client:
The code looks like this right now:
def __init__(self, callback_fun = None)
at the client calling site I have something like this:
def printme(modulename, codename, lineno, line):
paws = pawprints(callback_fun = printme)
1) Is this the correct way to do this (the code does seem to work OK).
2) If so, then is there a way to specify the function signature at
callback site rather than the client site?
It seems backwards to me because because if I get the function
definition wrong in the client site then I get a traceback to the
callback site - which is meant to be an opaque library that the client
should not have to know about.
