当孩子扩展一个类时，是否有一些神奇的方法被调用？

class Parent:
     
    @classmethod
    def __extends__(cls, child_cls):
        pass
    
# trigger __extends__ method
class Child(Parent): pass

    是的

    class Parent:
  def __init_subclass__(child_cls):
    # do magic with child_cls
    return

# this call __init_subclass__ parent method
class Child(Parent): 
  pass
