In Python 3.4, to create an abstract class.Import the ABC (abstract base classes) module.from abc import ABC, abstractmethod Declare the abstract method using the @abstractmethod decorator.from abc import ABC, abstractmethod class ExampleAbstractClass(ABC): @abstractmethod def abstractmethod(self): ...

There's actually a way to do this, but instead of creating "specializations" of a class, you need to define all methods of a class in the class definition (which is what Python would look like, if without type annotations), and add a type constraint on the self parameter of the meth...
In Python, we can extend a class to create a new class from the existing one. This becomes possible because Python supports the feature of inheritance. Using inheritance, we can make a child class with all the parent class’s features and methods. We can also add new features to the chil...
It means that one cannot create an object of an abstract class. To explain with an abstract class example in Java: Imagine an abstract class named “Vehicle”. This class might have an abstract method called “move”. While the concept of moving is common to all vehicles, the way a car...
We then created a method called get_color(). Within a method in a class in Python, you want to pass in the parameter, self, into the method. self is a reference that when you name an object, it is referring to itself, one of its attributes. It's pretty self-descriptive and self-...

You need to instantiate your class. By doing so in my code cat = Cat("Sally") what python does is call the __init__ method of the class and return an Instance of it with everythin set/done as specified in the __init__method. In my case i set self.name = name which makes ,...
In this article, you have been introduced to the concept of a Python class and a Python class object. You have also been introduced to the ideas upon which a python class is built such as: encapsulation, the 'self' identifier, accessor methods and mutator methods. With this information, yo...
