What is the difference between Super and multiple inheritance in Python?
Note that because all python new-style classes subclass object, multiple inheritance always involves diamond inheritance. super has a lesser benefit of reducing requires changes if you rename or change the base class. In python 3, the arguments to super are optional, so you can just do super ().__init__ ().
How to do inheritance in Python?
To do inheritance, you can use any object instance as a prototype. In Python, C++, etc.. there are classes, and instances, as separate concepts. In order to do inheritance, you have to use the base class to create a new class, which can then be used to produce derived instances.
Is there a difference between Super and single-inheritance?
So when inheriting from a single parent, is there no difference or preferred one to use? The purpose of super is to handle inheritance diamonds. If the class inheritance structure uses only single-inheritance, then using super () will result in the same calls as explicit calls to the "parent" class.
