How do you implement function overloading in Python?
To achieve operator overloading, we define a special method in a class definition. The name of the method should begin and end with a double underscore (__). The + operator is overloaded using a special method named __add__() . This method is implemented by both the int and str classes.
What is the use of ad hoc polymorphism?
Ad-hoc Polymorphism allows functions having same name to act differently for different types. For example: The + operator adds two integers and concatenates two strings.
Which polymorphism can be used in place of overloading?
In programming languages, ad hoc polymorphism is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, because a polymorphic function can denote a number of distinct and potentially heterogeneous implementations depending on the type of argument(s) to which it is applied.

Is polymorphism supported in Python?
Yes,Python support polymorphism. The word polymorphism means having many forms. polymorphism is an important feature of class definition in Python that is utilised when you have commonly named methods across classes or sub classes.
Can you overload operators in Python?
We can overload all existing operators but we can’t create a new operator. To perform operator overloading, Python provides some special function or magic function that is automatically invoked when it is associated with that particular operator.
Why is overloading sometimes referred to as ad hoc polymorphism?
Ad hoc polymorphism is also known as function overloading or operator overloading because a polymorphic function can represent a number of unique and potentially heterogeneous implementations depending on the type of argument it is applied to.
What is polymorphism in function overloading?
Polymorphism in Function Overloading In computing, polymorphism is a property of object oriented programming in which a function can take different forms based on the number of arguments and their data types. All the functions will have the same name, but they will differ in their arguments.
What is the biggest reason for the use of polymorphism?
What is the biggest reason for the use of polymorphism? Explanation: Polymorphism allows for the implementation of elegant software.
How does python implement polymorphism?
Polymorphism in python defines methods in the child class that have the same name as the methods in the parent class. In inheritance, the child class inherits the methods from the parent class. Also, it is possible to modify a method in a child class that it has inherited from the parent class.
