Python 3 OOP: A Deep Dive

C3 linearization algorithm

Multiple inheritance in Python is well-behaved thanks to the . Each class has an MRO — you can see it with ClassName.__mro__ .

class Validator: def __set_name__(self, owner, name): self.name = name def __get__(self, obj, objtype=None): return obj.__dict__.get(self.name) python 3 deep dive part 4 oop high quality
