In this article we introduce Python magic methods are and show how to use them. We cover some common magic methods. Python magic methods are special methods that add functionality to our custom classes. They are surrounded by double underscores (e.g. __add__()). (Magic methods are also ...
They're everything in object-oriented Python. They're special methods that you can define to add "magic" to your classes. They're always surrounded by double underscores (e.g. __init__ or __lt__). They're also not as well documented as they need t...
Dunder or magic methods inPythonare the methods having two prefix and suffix underscores in the method name. Dunder here means “Double Under (Underscores)”. These are commonly used for operator overloading. Few examples for magic methods are:__init__, __add__, __len__, __repr__etc....
For instance, a.x has a lookup chain starting with a.__dict__['x'], then type(a).__dict__['x'], and continuing through the base classes of type(a) excluding metaclasses. However, if the looked-up value is an object defining one of the descriptor methods, then Python may ...
The normal methods need to be called, but the magic method is called automatically when some events happen. So if you want to customize your class, you can override the magic method. The most common operators, for loops, and class operations are all run on the magic method. ...
Built-in classes in Python define many magic methods. Use the dir() function to see the number of magic methods inherited by a class. For example, the following lists all the attributes and methods defined in the int class. Example: Define Static Method Copy print(dir(int)) #output: #[...

Various built-in types, classes, functions, as well as magic methods are all highlighted. Specifically, they are highlighted when they appear as names in user definitions. Although it is not an error to have classes and functions that mask the built-ins, it is certainly worth drawing attention...
(3) See the frames of all functions/methods on the stack at this step, each of which shows its local variables. Here at step 41 we see main() along with 4 recursive calls to init(). (4) See all objects on the heap at the current step. Here it shows a LinkedList instance with ...
