Python Classes

Classes are templates used to define the properties and methods of objects in code. They can describe the kinds of data the class holds and how a programmer interacts with them.

Attributes - Properties

Methods - Action

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def bark(self):
        print(f"{self.name} says woof! and its {self.age} years old")

my_dog = Dog("Buddy", 2)

my_dog.bark()

Class Definition: We start with the class keyword followed by Dog, the name of our class. This is the blueprint for creating Dog objects.

Constructor Method (__init__): This particular method is called automatically when a new Dog object is created. It initializes the object’s attributes. In this case, each Dog has a name and an age. The self parameter is a reference to the current instance of the class.

Attribute: self.name and self.age These are attributes of the class. These variables are associated with each class instance, holding the specific data.

Method: bark It is a method of the class. It’s a function that all Dog instances can perform. When called, it prints a message indicating that the dog is barking.

Python supports two types of methods within classes.

• StaticMethod
• InstanceMethod
