Python Classes

Python Classes

Python classes are a fundamental feature of the language and are used to define objects with properties and methods. A class is essentially a blueprint for creating instances of objects, each with its own unique properties and methods.

Classes in Python can contain attributes and methods, where attributes are variables that store data related to the object and methods are functions that define the behavior of the object. When a class is defined, it can be instantiated into multiple objects, each with its own set of values for the attributes.

Classes in Python also support inheritance, where a new class can be created based on an existing class, inheriting its attributes and methods, and then modifying them or adding new ones.

The syntax for defining a class in Python is very simple. It starts with the keyword class followed by the name of the class, and then a colon. The attributes and methods of the class are defined inside the class block using the appropriate syntax.

Here's an example of a simple Python class that defines a person object:

class Person:

    def __init__(self, name, age):

        self.name = name

        self.age = age

    def introduce(self):

        print(f"My name is {self.name} and I am {self.age} years old.")

# Creating an instance of the Person class

person1 = Person("K Patel", 30)

# Calling the introduce method on the person1 object

person1.introduce()

In this example, the Person class has two attributes: name and age, and one method: introduce(). The __init__() method is a special method that gets called when a new instance of the class is created, and it initializes the attributes with the values passed in.

The introduce() method prints out a simple introduction for the person object, using the attributes name and age. Finally, an instance of the Person class is created and the introduce() method is called on it.
