I have a class Log and I want to create another class NullLog which has all the same method names as Log, but all of its methods are set to the function do_nothing(). That way I can use a NullLog object in place of a Log object to prevent anything from being logged, without any errors occurring from methods that don’t exist being called.

I could use inspect.getmembers() as shown here to get all the methods in Log, then use exec() to assign methods with the same names on initialisation of a NullLog object, but it seems like there should be a better way.
