Python 3 Deep Dive: Mastering Advanced Object-Oriented Programming

super() is crucial for cooperative multiple inheritance, ensuring that base classes are initialized properly.

To achieve high-quality OOP in Python, you should focus on these four pillars: 1. Mastering the "Magic" (Dunder Methods) python 3 deep dive part 4 oop high quality

Writing production-grade Python requires balancing readability with performance. Memory Optimization with __slots__

@dataclass(frozen=True) class User: id: int name: str Part 4: OOP

Part 1: Mainly functional programming. Part 2: Mainly iterables, iterators and generators. Part 3: Mainly hash maps. Part 4: OOP. Python 3: Deep Dive (Part 4 - OOP) - Udemy

Duck typing is a cornerstone of Python: If it looks like a duck and quacks like a duck, it must be a duck . This means the type or class of an object is less important than the methods it defines, focusing on what an object can do rather than what it is. While this offers immense flexibility, it also has drawbacks like a lack of clarity and errors that are only caught at runtime. Advanced Attribute Access and Descriptors

class Descriptor: def __get__(self, instance, owner_class): ... def __set__(self, instance, value): ... def __delete__(self, instance): ...

class Vector: def __init__(self, x: float, y: float): self._x = x self._y = y def __repr__(self) -> str: return f"Vector(self._x, self._y)" def __str__(self) -> str: return f"(self._x, self._y)" def __eq__(self, other: object) -> bool: if not isinstance(other, Vector): return NotImplemented return self._x == other._x and self._y == other._y def __hash__(self) -> int: return hash((self._x, self._y)) Use code with caution. 2.
