继承与重写

class Animal:
   def speak(self) -> str:
       return "..."

class Dog(Animal):
   def speak(self) -> str:
       return "woof"

def make_speak(a: Animal):
   print(a.speak())

make_speak(Dog())

super 的使用

class Base:
   def __init__(self, name):
       self.name = name

class Sub(Base):
   def __init__(self, name, role):
       super().__init__(name)
       self.role = role
