For example operator + is used to add two integers as well as join two strings and merge two lists. It is achievable because '+' operator is overloaded by int class and str class. You might have noticed that the same built-in operator or function shows different behavior for objects of different classes, this is called Operator Overloading. Example

BetaPython does not limit operator overloading to arithmetic operators. We can overload comparison operators as well. Here's an example of how we can overload the < operator to compare two objects of the Person class based on their age: class Person: def __init__(self, name, ...

BetaVice versa, in Python = (plain assignment) is not an operator, so you cannot overload that, while in C++ it is an operator and you can overload it. << is an operator, and can be overloaded, in both languages -- that's how << and >> , while not losing their initial connotation of left and right shifts, also became I/O formatting operators in C++ (not in Python!-).

BetaIn this example, the Name class defines the __add__() method to concatenate two names. When two Name instances are added using the ‘+’ operator, this method is invoked to perform concatenation.. These examples illustrate how operator overloading in Python enables custom behavior for operators, making code more intuitive and expressive.

BetaOperator overloading is the process of using an operator in different ways depending on the operands. You can change the way an operator in Python works on different data-types. A very popular and convenient example is the Addition (+) operator .

BetaIn this example, the __add__ method is defined to handle the + operator for Vector objects. When v1 + v2 is executed, the __add__ method is called, which returns a new Vector object representing the sum of the vectors.. Overloading Comparison Operators. Now let’s see how to overload comparison operators. We’ll extend our Vector class to include equality (==) and less than (<) comparisons.

BetaHow to overload an operator in python? To perform operator overloading, Python provides some special function or magic function that is automatically invoked when it is associated with that particular operator. For example, when we use + operator, the magic method __add__ is automatically invoked in which the operation for + operator is defined.

BetaThis post, however, deals with operator overloading in particular. Operator Overloading. Operator overloading refers to the ability to define an operator to work in a different manner depending upon the type of operand it is used with. A very noticeable example of this case in Python by default is the difference in the result obtained when ...

Beta2. Creating a Custom Class and Implementing Operator Overloading: You can specify how your class interacts with the Python operators (+, -, *, /, etc.) by developing a custom class and implementing operator overloading. This facilitates easy interaction with typical Python functions and makes your code more understandable and legible.

BetaIn this tutorial, we have discussed operator overloading in Python with the help of various example programs. Operator overloading is not a unique concept to Python, but it is found in various programming languages, but its implementation may differ. We cannot overload all Python operators.
