magic methods, also known as dunder methods (short for "double underscore"), are special methods in python that start and end with two underscores. these methods allow developers to define how objects behave in various situations. understanding and implementing magic methods is crucial for creating python classes that can seamlessly integrate with the language's built-in features, such as iteration, comparison, and customization.
let's explore some commonly used magic methods along with code examples to illustrate their usage.
the _init_ method is called when an object is created. it initializes the object's attributes.
these methods control the string representation of an object. _str_ is used by the str() function, and _repr_ is used by the repr() function and the interactive interpreter.
the _len_ method allows an object to define its length, which is called by the len() function.
these methods allow objects to be accessed and modified using square bracket notation.
these methods define the equality and inequality comparisons between objects.
these examples cover only a fraction of the available magic methods in python. exploring and understanding these methods allows you to customize the behavior of your classes, making your code more expressive and idiomatic.
