The inheritance is the process of acquiring the properties of one class to another class. class CustomError(MyProjectError): '''A custom exception class for MyProject.''' You can subclass custom exception classes as well to create a hierarchy. To create a specific exception, subclass the base exception class. To put it short, inheritance lets you reuse code. Organizing the exception classes in a separate module (e.g. You will learn how to use classes to represent data in concise and natural ways. ![]() In other words, the members of the parent class are inherited to the child class. This course introduces classes, instances, and inheritance. Python supports inheritance with an use of a minimum number of syntax and semantics. It comes handy in a lot of scenarios while designing or developing a complex software. The idea behind the class inheritance is to create a parent class-child class hierarchy. Inheritance is one of the core topic of object oriented programming. def _init_ ( self, age, location, ** kwargs ): # added **kwargs. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Python supports class inheritance, also called subclassing. def _init_ ( self, first_name, last_name ). Inheritance allows you to inherit the properties of a class, i.e., base class to another, i.e., derived class.
