This is useful if you're making mixins that each add a little something to the same set of functions, and there's no guaranteed that the base class has those functions defined, or perhaps there is no base class in common and you don't want to be bothered with thinking about method resolution order between your mixins.

maybe_super.py

def maybe_super(cls, self, method_name, base_value=None):
	""" Call the super method if it exists.

	Use it like this:

	def some_method(self, *args, **kwargs):
		result = maybe_super(MyClass, self, 'some_method')(*args, **kwargs)

	"""
	sup = super(cls, self)
	method = getattr(sup, method_name, None)
	if method:
		return method
	else:
		return lambda *args, **kwargs: base_value
		# method(*args, **kwargs)
