#for_A2 In object-oriented programming (OOP), a class is a blueprint for creating objects. It defines the properties (attributes) and methods (behaviors) that are common to all objects of a particular type. Classes are like the templates that allow you to create multiple objects with similar characteristics.
Properties
Properties, also known as attributes, are the characteristics of an object. They are like the individual features that define a specific instance of a class. For example, a car class might have properties such as color, brand, and model.
Methods
Methods, also known as behaviors, are the actions that an object can perform. They are like the instructions that define how an object interacts with the world around it. For example, a car class might have methods such as start(), stop(), and accelerate().
Creating Objects from Classes
Objects are created from classes using a process called instantiation. This involves providing the necessary values for the object's properties. For example, to create a car object, you would specify the color, brand, and model.
Example: Car Class
Consider a class named Car that represents a car object:
class Car:
def init(self, color, brand, model):
self.color = color
self.brand = brand
self.model = model
def start(self):
print("Starting the car...")
def stop(self):
print("Stopping the car...")
def accelerate(self):
print("Accelerating the car...")

This class defines the properties color, brand, and model for a car object. It also defines methods start(), stop(), and accelerate() for performing actions related to a car.
Using this class, you can create car objects and interact with them:
car1 = Car("red", "Toyota", "Camry")
car2 = Car("blue", "Honda", "Civic")
car1.start() # Output: Starting the car...
car2.accelerate() # Output: Accelerating the car...
car1.stop() # Output: Stopping the car...

Classes provide a structured and organized approach to creating and managing objects in OOP. They allow you to define and reuse common characteristics and behaviors for different types of objects, making programming more efficient and maintainable.

Consider a class named Car that represents a car object:
The Car class is like a blueprint or template for creating car objects.
Each car object has properties like color, brand, and model. These properties are like the attributes of a car.
Each car object can perform actions like starting, stopping, and accelerating. These actions are like the methods of a car.
Using the Car class, you can create multiple car objects, each with its own unique properties and behaviors.
Benefits of Using Classes
Classes promote code reuse by allowing you to define common characteristics and behaviors once and use them for multiple objects.
Classes improve code organization by grouping related properties and methods together.
Classes enhance code maintainability by making it easier to modify and update common functionalities.

Variables and Simple Data Types
In Python, you can store different types of data using variables. Variables are like containers that hold information.
Running a Python Program
When you run a Python program, the Python interpreter reads through the code and executes it line by line.
Syntax Highlighting
Your editor uses different colors to highlight different parts of your Python code, making it easier to read and understand.
Using Variables
Variables allow you to store and retrieve information in your programs. They have names and values.
Changing Variable Values
You can change the value of a variable at any time in your program.
Variable Naming Rules
Follow these rules when naming variables:
Use only letters, numbers, and underscores
No spaces, use underscores to separate words
Avoid Python keywords and function names
Use short but denoscriptive names
Be Careful with l and O
The lowercase letter l and the uppercase letter O can be confused with the numbers 1 and 0.
