The super() function in Python is used to call a method in a parent class from a child class. It is often used in object-oriented programming when you want to call a method in a parent class that has been overridden in a child class.
The general syntax of the super() function is as follows:
super(subclass, object).method(args)
Here, subclass is the child class that is calling the parent method, object is an instance of the subclass, and method is the name of the method that is being called.
For example, consider the following code:
class Parent: def my_method(self): print("Parent class method") class Child(Parent): def my_method(self): super().my_method() print("Child class method") child = Child() child.my_method()
In this example, we define a Parent class with a method my_method(), and a Child class that inherits from Parent. The Child class overrides the my_method() method of the Parent class and calls the my_method() method of the Parent class using the super() function. Then, it prints its own message "Child class method". Finally, we create an instance of the Child class and call the my_method() method on it.
When we call child.my_method(), the output will be:
Parent class method Child class method
This is because the my_method() method of the Child class first calls the my_method() method of the Parent class using super().my_method(), and then prints its own message.
The super() function is useful in situations where you want to call a method in a parent class that has been overridden in a child class, but you still want to execute the code in the parent class.
