Operator Overloading in Python

Operator overloading in Python is the ability of a single operator to perform more than one operation based on the class (type) of operands. For example, the + operator can be used to add two numbers, concatenate two strings or merge two lists.

What is operator overloading with example?

This means C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. For example, we can overload an operator '+' in a class like String so that we can concatenate two strings by just using +.

Is there function overloading in Python?

Conclusion. Python supports both function and operator overloading. In function overloading, we can use the same name for many Python functions but with the different number or types of parameters.

How do you overload a string in Python?

You have already seen you can use + operator for adding numbers and at the same time to concatenate strings. It is possible because + operator is overloaded by both int class and str class. The operators are actually methods defined in respective classes.

How do you do operator overloading?

Operator Overloading in Binary Operators

Here, + is a binary operator that works on the operands num and 9 . When we overload the binary operator for user-defined types by using the code: obj3 = obj1 + obj2; The operator function is called using the obj1 object and obj2 is passed as an argument to the function.

What are the types of operator overloading?

Overloading Unary Operator: Let us consider to overload (-) unary operator. In unary operator function, no arguments should be passed. It works only with one class objects.
...

• Overloading unary operator.
• Overloading binary operator.
• Overloading binary operator using a friend function.

WHAT IS function and operator overloading?

C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively. ... The process of selecting the most appropriate overloaded function or operator is called overload resolution.

What is __ init __ in Python?

"__init__" is a reseved method in python classes. It is called as a constructor in object oriented terminology. This method is called when an object is created from a class and it allows the class to initialize the attributes of the class.

Is overriding possible in python?

In Python method overriding occurs by simply defining in the child class a method with the same name of a method in the parent class. When you define a method in the object you make this latter able to satisfy that method call, so the implementations of its ancestors do not come in play.

What is __ add __ in Python?

Modifying the __add__ method of a Python Class

We can define the __add__ method to return a Day instance with the total number of visits and contacts: class Day(object):

What are Python functions?

A function is a block of organized, reusable code that is used to perform a single, related action. ... As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions.

What are basic overloading methods in Python?

Method Overloading:

• Method Overloading is the class having methods that are the same name with different arguments.
• Arguments different will be based on a number of arguments and types of arguments.
• It is used in a single class.
• It is also used to write the code clarity as well as reduce complexity.

What is overloading an operator?

In computer programming, operator overloading, sometimes termed operator ad hoc polymorphism, is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by a programming language, a programmer, or both.
