Python Special Functions In Python, methods that have two underscores,__, before and after their names have a special meaning. For example,__add__(),__len__()etc. These special methods can be used to implement certain features or behaviors. Let's use the__add__()method to add two n...
Operator overloading is an essential process in OOP, which adds multiple functions to the available operators. Operator overloading is the process of extending the predefined function of an operator to user defined functions. For example, the operator + is used to add two integers, join two st...
Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...
We do this by checking if it is an instance of int or float (you could also check complex if you wanted the Matrix class to support complex number, but we won't bother in this example). If the value is a number, we execute the code for the scalar multiplication equation above. If ...
In this program, we overload theabsolute()function. Based on the type of parameter passed during the function call, the corresponding function is called. Example 2: Overloading Using Different Number of Parameters #include<iostream>usingnamespacestd;// function with 2 parametersvoiddisplay(intvar...
Operator Overloading in Python _ Python Tutorial - Day #77 #include <iostream> class Cents { private: int m_cents {}; public: Cents(int cents) : m_cents { cents } { } // Overload Cents + int Cents operator+(int value) const; int getCents() const { return m_cents; } }; /...
Python invokes __add__. When you print the result, Python invokes __str__. So there is quite a lot happening behind the scenes. Changing the behavior of an operator so that it works with user-defined types is called operator overloading. For every operator in Python there is a correspo...

The accusation is frequently made at C++ and Haskell that they are unreadable due to excessive use of obscure operators. On the other hand, in the Python ecosystem, operators are generally considered to make code significantly cleaner, e.g., in their use in NumPy. ...
