Operator overloading

In this section, we will learn about operator overloading with special methods. Generally, people call them magic methods. We will use these methods in operator overloading. First, let's understand what operator overloading is. Using a special method, we'll able to change the built-in behavior of the operator. The special method is surrounded by double underscores (__). Some people called it the dunder method. Let's take an example of the + operator, as shown in the following example:

>>> "M"+"R"
'MR'
>>> 4+6
10
>>>

You can see a different behavior of the + operator. The integer number is added and the strings are concatenated. Depending upon the object you are working with, the + operator has different behavior. However, the + calling is a special method that runs in the background. In order to do addition of two integers, the + operator calls int.__add__(1,2) and for string addition + calls str.__add__(“a”, “b”). Refer to the following example...
