Creating a Simple Car Class With Python

Introduction:

Classes in Python are fundamental to object-oriented programming. This example demonstrates class creation and object-oriented programming concepts by defining a simple car class.

Code:

pythonCopy codeclass Car:
    def __init__(self, brand, model, year):
        self.brand = brand
        self.model = model
        self.year = year
        self.mileage = 0
    
    def show_info(self):
        print(f"Car: {self.brand} {self.model} ({self.year})")
        print(f"Mileage: {self.mileage} km")
    
    def add_mileage(self, km):
        if km >= 0:
            self.mileage += km
            print(f"Mileage increased by {km} km.")
        else:
            print("You entered a negative value. Mileage increase failed.")

# Sample usage
car1 = Car("Toyota", "Corolla", 2020)
car1.show_info()

car1.add_mileage(100)
car1.show_info()

car1.add_mileage(-20)  # Negative mileage increase
car1.show_info()

Explanation:

In the provided code, a class named "Car" is defined. It specifies properties such as brand, model, year, and mileage for each car. The init method is the constructor of the class, called when a Car object is instantiated. The show_info method displays the car's details, while the add_mileage method updates the car's mileage.

Result:

This example illustrates how to create a simple car class and how to utilize it. Classes and object-oriented programming enable us to manage complex systems in a more modular and organized manner.
