This section describes what is a Superclass and a Subclass - a pair of classes that the second class extends from the first class. An object of subclass inherits all properties and operations from the superclass
MRO is a mechanism to resolve the method to be executed when super notation is used. A common confusion occurs in case of multiple inheritance. What if a common method is implemented in multiple parents and it is called using super(), from which class should the method be called? This is...

Another benefit of using inheritance is that it lets us treat a subclass as if it was a superclass. For example, let's say a program has created multiple instances of the Man and Woman objects. The program might need to call the sleep behavior for all these objects. Because the sleep b...
Method Overriding: Subclasses can override superclass methods. When a method is called on an instance of the subclass, Python first looks for the method in the subclass. If not found, it looks for a method in the superclass. Single Inheritance: Python supports single inheritance, which means ...
What is an example of polymorphism? Sure, let's say we have a superclass called Animal with a method makeSound(). We can have subclasses like Dog, Cat, and Bird that inherit from Animal and override the makeSound() method with their own unique implementation. When you call the makeSound...
You can then override existing methods in the subclass to modify their behavior or add new methods to extend functionality. This approach is clean and organized, and promotes code reusability. Example (Python): classSuperClass:defmy_method(self):print("Original method")classSubClass(SuperClass):de...
For item 1, Django lets us define a URL "prefix" to say that any URLs which start with that prefix should be treated as requests for static files. By default, the prefix is/static/. It’s defined insettings.py: superlists/settings.py ...
This approach is clean and organized, and promotes code reusability. Example (Python): class SuperClass: def my_method(self): print("Original method") class SubClass(SuperClass): def my_method(self): print("Modified method") super().my_method() # Call the original method subclass_instance...
