Python Magic Methods and Dunder Methods: How Python Objects Really Work
If you've been using Python for a while, you've probably seen methods like __init__() , __str__() , __len__() , and __eq__() . They may look a little unusual because of the double underscores. These are called magic methods or dunder methods . But the interesting part isn't the naming convention. The real value of dunder methods is understanding how Python objects interact with the language…
The article discusses the concept of magic methods or dunder methods in Python, which are methods with double underscores such as __init__(), __str__(), __len__(), and __eq__(). These methods allow custom objects to behave like native Python objects and enable Python to internally use special methods defined by the object's class when performing operations like len(order), print(order), or item = products[0].
Understanding dunder methods is crucial for full-stack developers, as they frequently use custom objects in various layers of a typical backend application, including order objects, user objects, API response objects, database entities, and custom collections. By understanding and utilizing dunder methods, developers can make their objects behave naturally and simplify their code.
