Python Classes/Objects. Python is an object oriented programming language. Almost everything in Python is an object, with its properties and methods. A Class is like an object constructor, or a "blueprint" for creating objects.
- Python Classes. A class is considered a blueprint of objects. We can think of the class as a sketch (prototype) of a house. It contains all the details about the floors, doors, windows, etc.
- Define Python Class. We use the class keyword to create a class in Python. For example, class ClassName: # class definition. Here, we have created a class named ClassName.
- Python Objects. An object is called an instance of a class. Suppose Bike is a class then we can create objects like bike1, bike2, etc from the class. Here's the syntax to create an object.
- Access Class Attributes Using Objects. We use the . notation to access the attributes of a class. For example, # modify the name property bike1.name = "Mountain Bike" # access the gear property bike1.gear.
Create an object in Python. To create an object, we use the following syntax. Syntax of how to create Object in Python. object_name = ClassName(arguments) Using the above syntax, let’s create an object of the class Dog. Example of creating Object in a Class. dog1 = Dog("Snoopy", 3) print(dog1) Output.

- Creating a Python Class. Here, the class keyword indicates that you are creating a class followed by the name of the class (Dog in this case). Python3. class Dog
- Object of Python Class. An Object is an instance of a Class. A class is like a blueprint while an instance is a copy of the class with actual values. It’s not an idea anymore, it’s an actual dog, like a dog of breed pug who’s seven years old.
- Example of Python Class and object. Creating an object in Python involves instantiating a class to create a new instance of that class. This process is also referred to as object instantiation.
- __init__() method. The __init__ method is similar to constructors in C++ and Java. Constructors are used to initializing the object’s state. Like methods, a constructor also contains a collection of statements(i.e.
- Python Class and Object. class Parrot: # class attribute name = "" age = 0 # create parrot1 object parrot1 = Parrot() parrot1.name = "Blu" parrot1.age = 10 # create another object parrot2 parrot2 = Parrot() parrot2.name = "Woo" parrot2.age = 15 # access attributes print(f"{parrot1.name} is {parrot1.age} years old") print(f"{parrot2.name} is {parrot2.age} years old")
- Python Inheritance. Inheritance is a way of creating a new class for using details of an existing class without modifying it. The newly formed class is a derived class (or child class).
- Python Encapsulation. Encapsulation is one of the key features of object-oriented programming. Encapsulation refers to the bundling of attributes and methods inside a single class.
- Polymorphism. Polymorphism is another important concept of object-oriented programming. It simply means more than one form. That is, the same entity (method or operator or object) can perform different operations in different scenarios.
Object-oriented programming (OOP) is a method of structuring a program by bundling related properties and behaviors into individual objects. In this tutorial, you’ll learn the basics of object-oriented programming in Python. Conceptually, objects are like the components of a system. Think of a program as a factory assembly line of sorts.

Aug 19, 2024 · Creating Objects From a Class in Python. The action of creating concrete objects from an existing class is known as instantiation. With every instantiation, you create a new object of the target class. To get your hands dirty, go ahead and make a couple of instances of Circle by running the following code in a Python REPL session:
