In this article, we will be comparing Python 3 Classes by exploring the differences between various aspects of class creation in Python. This comprehensive guide aims to provide a detailed understanding of the syntax and functionality of class creation in Python. We will compare different features including inheritance, encapsulation, polymorphism, and much more.

Class Basics

A class is a blueprint for creating objects that have common attributes and methods. The basic syntax for defining a class in Python is:

Type of Attribute Description
Class Name The name of the class, which should always start with a capital letter.
Object Inside Parentheses A class can inherit from another class if the string has one or more parent classes. If there are no additional parent classes for inheritance, empty parentheses can be used instead.


Encapsulation refers to the concept of bundling data and methods together within a class such that they are hidden away from external access. This is achieved in Python by defining private variables and methods with a “double underscore” (__) prefix.

Private Variables

Private variables are those that are not intended to be accessed by external objects. They can be defined using the double underscore prefix as follows:

Private Methods

Private methods can be defined in much the same way as private variables, using the double underscore prefix before the method name. The main difference is that instead of hiding data from external access, private methods are used to perform internal operations that should not be exposed to external objects.


Inheritance allows a new class to be based on a pre-existing class, with the new class inheriting all of its attributes and methods. This is achieved in Python by providing the name of the parent class within parentheses when defining a new class.

Single Inheritance

Single inheritance involves creating a new class based on one pre-existing class. Single inheritance can be used to build complex class hierarchies without having to redefine common attributes and methods for each new class.

Multiple Inheritance

Multiple inheritance allows a new class to inherit from two or more parent classes. This is achieved by listing the parent classes separated by a comma within parentheses when defining a new class.


Polymorphism refers to the ability of different objects to be represented as instances of the same class, despite having different structures and behaviors.

Method Overloading

Method overloading involves defining multiple methods with the same name but different parameters within a class. This allows for different versions of a method to be called based on the parameters provided.

Method Overriding

Method overriding involves defining a method in a child class with the same name as a method defined in the parent class. This allows the child class to use its own version of the method instead of the parent class’s method.


Overall, Python 3 offers a wide range of features for creating classes, each with their own advantages and disadvantages. By understanding the different aspects of class creation in Python, developers can make informed decisions about which features to use and how to implement them. With this knowledge, you can create robust and flexible classes in Python that can be tailored to the specific needs of your project.

Thank you for reading this comprehensive guide on comparing Python 3 classes. We hope that this article has given you a better understanding of the different types of classes in Python and how to compare them effectively.

As you have learned, there are many factors to consider when comparing classes such as inheritance, encapsulation, and polymorphism. Each type of class has its own strengths and weaknesses, and it is up to you to determine which one is best suited for your specific needs.

Whether you are new to Python or an experienced programmer, understanding classes is essential to building robust and scalable applications. We encourage you to continue exploring the many features of Python and to stay up-to-date with the latest developments in the language.

People Also Ask About Comparing Python 3 Classes: A Comprehensive Guide:

  1. What is a class in Python?
  • A class in Python is a blueprint for creating objects. It defines a set of attributes and methods that are shared by all instances of the class.
  • What is the difference between a class and an object in Python?
    • A class is a template or blueprint for creating objects, while an object is an instance of a class.
  • What are the benefits of using classes in Python?
    • Classes provide a way to organize and encapsulate data and behavior, making code more modular and easier to maintain. They also allow for inheritance and polymorphism, which can aid in code reuse and abstraction.
  • What is inheritance in Python?
    • Inheritance is the ability of a subclass to inherit attributes and methods from its parent class. This allows for code reuse and promotes modularity.
  • What is polymorphism in Python?
    • Polymorphism refers to the ability of objects to take on different forms or behaviors depending on the context in which they are used. In Python, this can be achieved through method overriding and duck typing.
  • What are some best practices for writing Python classes?
    • Some best practices for writing Python classes include adhering to the single responsibility principle, using descriptive names for variables and methods, and avoiding mutable default arguments.
