Inheritance_Training

Inheritance_Training is a programming concept that allows a class to inherit properties and methods from another class, referred to as the parent or base class. This allows for code reuse and helps improve the organization and readability of code.

Benefits of Inheritance_Training
  1. Code Reusability - Inheritance_Training allows you to use code from existing classes in new classes. This can save time and effort when developing new applications.
  2. Improves Code Organization - Inheritance_Training helps to group classes into a hierarchy, making it easier to understand and navigate the code.
  3. Reduces Code Repetition - With Inheritance_Training, you can define methods and properties in the parent class and then reuse them in any of the child classes. This reduces the amount of code you need to write and maintain.
  4. Easier to Update - With Inheritance_Training, changes made to the base class will be automatically applied to all child classes that inherit from it.
  5. Encourages Modularity - Classes that inherit from a parent class can be developed and tested independently, which helps to promote modularity in your code.
Types of Inheritance_Training
  1. Single Inheritance_Training - A child class inherits from a single parent class.
  2. Multiple Inheritance_Training - A child class inherits from two or more parent classes.
  3. Multi-level Inheritance_Training - A child class inherits from a parent class, which in turn inherits from another parent class.
Implementing Inheritance_Training in Code

To implement Inheritance_Training in your code, you need to define a parent class and one or more child classes. The child classes will inherit properties and methods from the parent class.

Example:
# Define a parent class
class Vehicle:
  def __init__(self, make, model, year):
    self.make = make
    self.model = model
    self.year = year

  def start_engine(self):
    print("Starting engine")

# Define a child class that inherits from the parent class
class Car(Vehicle):
  def __init__(self, make, model, year, num_doors):
    # Call the constructor of the parent class to initialize the make, model, and year properties
    super().__init__(make, model, year)
    self.num_doors = num_doors

  def unlock_doors(self):
    print("Unlocking doors")

# Create an object of the Car class and call its methods
my_car = Car("Toyota", "Camry", 2022, 4)
my_car.start_engine()
my_car.unlock_doors()

In this example, we define a parent class Vehicle that has a constructor and a start_engine method. We then define a child class Car that inherits from Vehicle and has an additional property num_doors and a method unlock_doors. We create an object of Car and call its methods. The start_engine method is inherited from the parent class.
