def get_balance(self): return self.__balance
Polymorphism allows objects of different classes to respond to the same interface. In Python, this is implemented through dunder (double underscore) methods—special methods that enable custom classes to integrate seamlessly with Python's built-in syntax and functions.
: Data descriptors (defining both get and set) take precedence over instance dictionaries, while non-data descriptors (only get) do not. python 3 deep dive part 4 oop high quality
Polymorphism in Python is largely driven by .
This approach—sometimes called "duck typing" combined with protocol implementation—is a defining characteristic of idiomatic Python OOP. Instead of inheriting from abstract base classes (though those exist too), you simply implement the required methods, and Python's dynamic dispatch handles the rest. def get_balance(self): return self
: Understanding the relationship between properties and functions.
High-quality object-oriented programming in Python 3 is a skill that emerges from deep understanding, not superficial knowledge. It requires mastery of classes, methods, properties, inheritance, descriptors, metaprogramming, and the SOLID principles—all while writing code that feels natural and idiomatic to Python. Polymorphism in Python is largely driven by
