How To Create Derived Class From Base Class Universally In Python?
Simple Inheritance in Python
The below code defines two classes, `Animal` and `Dog`, where `Dog` is derived from `Animal`. It initializes attributes like species and breed, and the `make_sound` method is overridden in the `Dog` class. An instance of `Dog` is created, and its attributes, including those inherited from `Animal`, are accessed and printed, demonstrating the principles of inheritance in Python.
Python3
class Animal: def __init__( self , species): self .species = species def make_sound( self ): pass class Dog(Animal): def __init__( self , breed): super ().__init__( "Dog" ) self .breed = breed def make_sound( self ): return "Woof!" # Creating an instance of the derived class my_dog = Dog( "Labrador" ) # Accessing attributes and methods from both base and derived classes print (f "Species: {my_dog.species}, Breed: {my_dog.breed}, Sound: {my_dog.make_sound()}" ) |
Species: Dog, Breed: Labrador, Sound: Woof!
Universal Inheritance in Python
The below code defines two classes, `Shape` and `Circle`, where `Circle` is derived from `Shape`. It initializes attributes such as color and radius, and the `draw` method is overridden in the `Circle` class. An instance of `Circle` is created, and its attributes, including those inherited from `Shape`, are accessed and printed, showcasing the use of inheritance in Python for code reuse and extension.
Python3
class Shape: def __init__( self , color): self .color = color def draw( self ): pass class Circle(Shape): def __init__( self , radius): super ().__init__( "Red" ) self .radius = radius def draw( self ): return f "Drawing a red circle with radius {self.radius} units." # Creating an instance of the derived class my_circle = Circle( 5 ) # Accessing attributes and methods from both base and derived classes print (f "Color: {my_circle.color}, Draw: {my_circle.draw()}" ) |
Color: Red, Draw: Drawing a red circle with radius 5 units.
Conclusion
In conclusion , Creating derived classes from base classes universally in Python is a powerful concept that enhances the organization and extensibility of your code. It allows you to build upon existing functionalities, promoting a modular and scalable design. By understanding the syntax and examples provided, you can leverage universal inheritance to create a well-structured and efficient object-oriented Python codebase.
Create Derived Class from Base Class Universally in Python
In object-oriented programming, the concept of inheritance allows us to create a new class, known as the derived class, based on an existing class, referred to as the base class. This facilitates code reusability and structuring. Python provides a versatile way to create derived classes from base classes universally, allowing for flexibility and scalability in your code.
Syntax
To create a derived class from a base class universally in Python, we use the following syntax: In this syntax, DerivedClass
is created by mentioning BaseClass
in parentheses. This implies that DerivedClass
inherits the attributes and methods of the BaseClass
class BaseClass:
# Base class attributes and methods
class DerivedClass(BaseClass):
# Additional attributes and methods specific to the derived class
Advantages :
- Code Reusability: Universal inheritance enables reuse of code from the base class in derived classes, reducing redundancy.
- Ease of Maintenance: Modifications to the base class automatically propagate to all derived classes, simplifying code maintenance.
- Extensibility: Derived classes can build upon and customize functionalities of the base class.
- Consistent Interface: Provides a uniform interface across related classes, enhancing code readability.
- Polymorphism: Supports treating objects of derived classes as objects of the base class, promoting flexibility in code usage.
