The fundamental idea of object-oriented programming (OOP) is inheritance, which also enables the developer to create a new class on the basis of an old one. Such common programming languages like Python do not have polymorphism as a concept. Nevertheless, it is possible to adopt polymorphism in the Python platform through inheritance in the development of sophisticated codes that can be reused.
What is Inheritance or Inheritance in Python?
What is Inheritance in Python is one of the primary concepts in the Python interview. Inheritance in Python is a feature that allows an object to inherit the behaviour and properties of another one. It is the parent class or the superclass that is the inherited one and the other, which is the child or subclass. Every attribute and method of the parent group is inherited by the child group and the child group is able to create new attributes and methods or substitute the inherited attributes and methods of the parent group.
Advantages of Inheritance in Python
There are several advantages of inheritance; they are as follows:
·Code reusability: Since the use of inheritance, code reusability can be attained, that is, by exploiting the attributes and behaviour of a class created.
·Hierarchy Relationships: Inheritance helps in modelling hierarchy relationships between the classes, and therefore, complex systems could be modelled easily.
·Faster Modifications: The inheritance simplifies the modification or extension of the operation of a class without any impact on other components of the program.
The use of Inheritance in Python
In Python, inheritance is attained by the introduction of a child class and a parent class. The child class is created as a base class of the parent class syntax (ParentClass).
# Define a parent class
class Vehicle:
def __init__(self, brand, model):
self.brand = brand
self.model = model
def start_engine(self):
print("The engine is running.")
# Define a child class that inherits from the parent class
class Car(Vehicle):
def __init__(self, brand, model, num_doors):
super().__init__(brand, model)
self.num_doors = num_doors
def lock_doors(self):
print("The doors are locked.")
# Create an instance of the child class
my_car = Car("Toyota", "Corolla", 4)
my_car.start_engine() # Output: The engine is running.
my_car.lock_doors() # Output: The doors are locked.
Python Best Practices of Using Inheritance
In Python, inheritance should be used in the following best practices:
·The model has inheritance. Relationships between a child and a parent where the child represents a specialization of the parent should be modelled using inheritance.
·Maintain a shallow hierarchy of inheritance: A deep inheritance hierarchy makes the code more incomprehensible and harder to maintain.
·Use abstract classes and methods: An interface can sometimes be characterized by using abstract classes and methods to characterize a common interface into a set of related classes.
Python Course in Noida and Delhi
So, in case your interest is to know more about Python and inheritance, you should join a Python Course in Noida or Delhi. Assisted by such courses, you may acquire some working practice and tips from practitioners in learning a Python programming style. You will be capable of building a huge number of applications and will be able to fix complicated problems in various spheres, and the ability to do so will be based on the knowledge and the competencies that you have acquired during these courses.
Conclusion:
Another practical tool in Python is inheritance, which aids programmers in creating new classes based on older ones. Having known the advantages and types of inheritance, one can assist the developer to yield maximum value out of the inheritance in Python in order to come up with a scalable, robust, and comprehensive software system. There is a huge demand for Python professionals in cities like Noida and Delhi. Therefore, enrolling in the Python Programming Course in Delhi can be a wise career choice. You may be a beginner developer or an expert developer; still, the inheritance of Python codes will be able to bring your coding skills to a new level.
