The Python super () method allows you to access the methods of a parent class inside a child class. This helps reduce repetition in the code. super () takes no arguments. One of the main characteristics of object oriented programming languages ‚Äã‚Äãlike Python is inheritance. Inheritance occurs when a new class uses code from another class to create the new class.

When you inherit classes, you can have access to methods from a parent class. This is where the super () function comes in .

This tutorial will discuss the basics of inheritance in Python with examples. Next, we’ll talk about how to use the super () function for values ‚Äã‚Äãand methods to inherit from a parent class.

What is Super Python?

The super - Python () method allows you to access methods in a parent class. You can think of super () as a way of display methods in the class from which another class is inherited

Here is the syntax for the super () method.

The super () method takes no arguments. You specify the method you want to inherit after the super () method. The previous Python class inherits values ‚Äã‚Äãfrom the __init __ () method of the food class. We call super () class method to the values ‚Äã‚Äãinherit from the food class.

Python inheritance refers to a process in which a new class uses code from an existing class to define the structure of the new one class

One way to think about inheritance is to look at how children inherit characteristics from their children. parents. A child can have the same hair color as their parents and even inherit the last name from their parents.

In Python, there are two types of classes:.

  • Classes for children (or "Subclasses ") Inherit methods and variables. Child classes are sometimes called sister classes
  • Main classes (or "base classes") are classes whose values ‚Äã‚Äãcan be inherited

super () Python:. Inherit from __init __ ()

Suppose we create a bank account system that keeps track of the credentials of people who hold an account with a bank, we want to create a class that stores the data for account verification We could do it using this code:.

This code creates a current account project.

Now, suppose we want to create a class that stores the project for children’s bank accounts, which we’ll call ChildAccount. the class should be based on the CheckingAccount class we defined earlier. To do this we can use the super () function.

super () allows you to access the methods of a parent class within a child class.

In our example, our parent class, it’s called CheckingAccount and our child class is called ChildAccount. CheckingAccount creates the project for a bank account and ChildAccount inherits the values ‚Äã‚Äãfrom CheckingAccount to create its own class.

Now, suppose we want the ChildAccount class to inherit the values ‚Äã‚Äãstored in our CheckingAccount. But we also want this account to store a new value called is_child, which should be True by default.

We could create our new ChildAccount class using this code:

This code creates a project for our new ChildAccount class. We use the super () method to inherit the name and values ‚Äã‚Äãof the Balance CheckingAccount class. We specify CheckingAccount the parent class in parentheses in the first line of our class.

This shows that super () allows you to inherit all values ‚Äã‚Äãfrom another class. But, in our code, we also declared a new value called is_child . This value will not be accessible to any ChildAccount because it has been declared in the ChildAccount class

to create an instance of our class for a child account holder, we can use this code:

Our code returns:

We have declared an instance of ChildAccount class assigned to the Python variables lynn . lynn is a class object because we were declaring the value of lynn using an object.

Lynn’s account has $ 200 and the value of is_child is true by default. Next, we printed name, balance, is_child values ‚Äã‚Äãassociated with Lynn aunt of acc . We print these values ‚Äã‚Äãto the console using the print () Python method.

Why we inherited name and balance from the CheckingAccount class, we were able to use them in our code. However, Lynn’s account also has a set of values ‚Äã‚Äãfor is_child, which is set to True by default for all instances of ChildAccount.

super () Python: inherit Methods

super () allows classes to inherit using single level inheritance - a class inheriting from a parent class. Or you can use super () with multilevel inheritance . For this example, we will focus on single level inheritance with super ().

In our previous example, we used super () to Inherit the values ‚Äã‚Äãstored in the CheckingAccount class and make them available to the ChildAccount class. But what if we wanted to inherit from a method and modify its response

Either class back to our CheckingAccount go from start:

In this class we have defined the design for the values the class should store - name and balance. We have defined a method called Checkbalance () which allows a user to check their balance

Now suppose we want to make Checkbalance () accessible to our ChildAccount. We also want to print a message saying "You have a child account!" It appears before the user’s balance is printed to the console.

We can access our inherited methods like this:

We have declared a new version of the Checkbalance () method ChildAccount class. This first version displays "You have a child account!" to the console, so our super () code uses for the Checkbalance () of the mother class .

In this case, when super (). Checkbalance () is executed, the Checkbalance () function of CheckingAccount class is executed. Which displays the user’s balance on the console

Now we’ll try to access our Checkbalance () method on behalf of Lynn.

Our code returns:

When we call lynn.checkBalance () method, the code in our ChildAccount.checkBalance () method is race , the super object executes the code in the CheckingAccount.checkBalance () method.

The super () function allows us to use parent methods, while still being able to override those methods in our child classes.

Conclusion

The Python super () function allows you to inherit methods from a class parent. The super () function helps you write more readable code because you can reuse code from existing functions.

This tutorial has discussed, with examples, how to use the super () function. inherit values ‚Äã‚Äãand methods from a parent class. You are now equipped with the knowledge to start using the super () function like a Python pro!
