dunder methods, short for "double underscore" methods, are special methods in python that have double underscores at the beginning and end of their names (e.g., __init__, __str__, __add__). these methods are also known as magic methods or special methods. they provide a way to define how objects of a class behave in various situations. in this tutorial, we'll explore some common dunder methods and how to use them with code examples.
dunder methods are used to define how objects of a class behave in specific situations. they are invoked by python's interpreter, and you can override them to customize the behavior of your classes. here are some common dunder methods:
the _init_ method is used to initialize the object's attributes when an instance of the class is created. it's called automatically when you create a new object. here's an example:
the _str_ method is used to define a human-readable string representation of the object. it's called when you use the str() function or print() function with an object. here's an example:
the _repr_ method is used to define an unambiguous string representation of the object. it's called when you use the repr() function or when you enter an object in the python interpreter. here's an example:
the _eq_ method is used to define how objects of the class should be compared for equality. it's called when you use the == operator. here's an example:
the _add_ method is used to define the behavior of the + operator for objects of the class. you can customize what happens when you add two objects together. here's an example:
you can define custom dunder methods for your classes to control their behavior in various contexts. by overriding these methods, you can make your classes more intuitive and user-friendly.
dunder methods in python allow you to customize the behavior of your classes in various contexts, making your code more expressive and user-friendly. understanding and using dunder methods effectively is an essential skil ...
