Question

In C# I would go:

myObj.base

I have a Date class which inherits from date.datetime. The Date class overrides __gt__() and __lt__() so when using the < and > operators they are called. I do not want to use these overrides – I want to use the date.datetime methods on an instance of Date.

Use super() to get the superclass object. Type help(super) in the Python command prompt.

From the manual:

class super(object)
 |  super(type) -> unbound super object
 |  super(type, obj) -> bound super object; requires isinstance(obj, type)
 |  super(type, type2) -> bound super object; requires issubclass(type2, type)
 |  Typical use to call a cooperative superclass method:
 |  class C(B):
 |      def meth(self, arg):
 |          super(C, self).meth(arg)

Let class B be a subclass of class A and class A have a method def f(self)::

• In Python 2, you can call a superclass method in class A from derived class B by using super(B, self).f().
• In Python 3, you can use super().f() without the B, self arguments.
