Briefly stated, a function is a “block” of code that you may reuse repeatedly rather than having to write it out several times. Programmers can divide an issue into smaller, more manageable parts, each of which can carry out a specific task, using functions. The specifics of how a function operates can virtually be forgotten once it has been built. By abstracting the specifics, the programmer may concentrate on the broad picture. Once a function has been created by a programmer, he can use its name to invoke it whenever they need it. The function also likely needs some inputs or arguments to operate, which are passed to the function every time it is called.
The computer language Python supports several concepts, including functional programming and object-oriented programming (OOP). Python is used to develop web and mobile applications, in machine learning (ML) and artificial intelligence (AI), to manipulate and analyze data, and much more. A function in Python is a collection of connected instructions that carry out a certain activity. Functions assist in segmenting our program into manageable, modular portions. Our program becomes more organized and controlled as it gets bigger and bigger. It also renders the code reusable and prevents repetition.

Super Function in Python
Python is an object-oriented programming language, as is common knowledge. As a result, Python adheres to all OOPs principles, including inheritance. By employing the super() function in python inside the inherited or child class, we can refer to a parent class when using the inheritance idea. The super() function in python, which we use with the child class produces an object of the superclass that is temporarily constructed and gives us access to all of its methods that are present in the child class. There are some benefits for super() function when used in child class. They are:
- The class name of the parent’s class is not necessary to remember when utilizing the super() function. This is so that we can access the parent class’s methods without having to mention its name.
- Both single inheritance and multiple inheritances are compatible with the super() function.
- Since we don’t need to repeatedly rebuild the entire method, Python’s super() function provides code reuse and modularity.
- Since Python is a dynamically typed programming language, the super() function is also referred to as a dynamic function.
There are some constraints for using super() in python. They are:
- The arguments in the function that we called should match those in the super() function, which provides the arguments.
- The super() keyword should appear after every instance of the method we’re using.
- The class and its methods, to which the super() function refers, must be specified.
How to Implement super function in python
In Python, we can utilize the super() function for both single- and multiple-generation inheritances. As a result, we will cover both types of inheritance separately and with an example before learning how to use the super() function. Inheritance may be a foreign idea to you if you’re not familiar with object-oriented programming concepts. A class can derive (or inherit) characteristics and actions from another class in object-oriented programming without having to implement them again. Python super is implemented in two inheritances. They are:
Implementing super in python for both these inheritances is different. Let us look into super in python in single inheritance first.
In singles inheritance, super in python is used to refer to the root class. In the example of implementing super () in python for a single inheritance, animals will serve as our model for single inheritance. The class Animalia includes animals including cats, horses, cows, dogs, and more. Additionally, they all have the following traits in common: They are all companion animals. Each of them has a tail and four legs. They are all mammals and belong to the class Animalia. Therefore, we might conclude that the subclasses of the class Animalia are the classes of cats, horses, and dogs. Because class Animalia is the only parent class inherited from, all of the subclasses (class cats, class horses, and class dogs) are examples of single inheritance.
In the case of implementing super() in python in multiple inheritances, we will utilize the mammal class as a parent class. The classes “Can Fly” and “Can Swim” will thereafter be passed down to us from the animal class. These categories will indicate whether a specific mammal can fly and swim. Following that, we will construct an animal class that will be descended from the Can Fly and Can Swim classes and indicate whether or not the given animal possesses the specified traits. As a result, we can see that the animal class we’re using here is an example of multiple inheritances in Python because it has ancestries from many base classes.

Functions are an important feature provided by every programming language. In python among all functions, the super() function is an important one. It is based on two instances viz, single and multiple inheritances. It is explained with the help of the common example of animals. As an Object Oriented Programming language, python developers get great help from functions for developing projects.
