What are the advantages of encapsulation and inheritance in Python?

Encapsulation helps in bundling data and methods, protecting the internal state of an object. Inheritance allows code reuse and establishes a relationship between classes.

Can you give me an example of encapsulation in Python?

Sure! In Python, you can use private variables by prefixing them with an underscore. For example:

class Car:
    def __init__(self):
        self.__speed = 0  # private variable

    def set_speed(self, speed):
        self.__speed = speed

    def get_speed(self):
        return self.__speed

How does inheritance improve code organization?

Inheritance allows you to create a base class with common functionality and then extend it in derived classes. This reduces code duplication and enhances maintainability.

What are some real-world applications of these concepts?

Real-world applications include frameworks like Django, where encapsulation protects data integrity, and inheritance allows for modular and reusable code.
