super() in Python
super() function is crucial for creating efficient and maintainable code. This powerful tool allows you to call methods from a parent class in a child class, enabling code reusability and maintaining a clear inheritance hierarchy.
Python super()
The super() function in Python is a built-in function that provides a way to call methods and access attributes from the parent class within a subclass. It is particularly useful when dealing with inheritance, as it allows you to extend the functionality of the parent class while retaining its methods and attributes.
Syntax:
The super() function is called with two arguments: the first argument is the subclass that wants to access the parent class, and the second argument is the instance of that subclass. Let’s understand it with an example:
Example:
class Parent:
def show(self):
print("This is a Parent class")
class Child(Parent):
def display(self):
print("This is a Child class")
def show(self):
super().show()
child = Child()
child.display()
child.show()
Output :
This is the Child class
This is the Parent class
You can also pass additional arguments to the super() function when calling it within a method. This allows you to customize the behavior of the parent class’s method based on the needs of the child class.
Advantages of super()
- Code Reusability: super() promotes the reuse of code by allowing you to access and modify the behavior of parent class methods.
- Maintainability: Inheritance hierarchies become more transparent, making code easier to maintain.
- Consistency: super() ensures that the parent class’s methods are consistently invoked, even in complex inheritance structures.
