python 多重继承构造函数调用顺序

• 实例代码

  class Person(object):
      def __init__(self, name, age):
          self.name = name
          self.age = age
          print("父类构造函数")
  
  
      def talk(self):
          print("person is talking....")
  
  
  class Chinese(Person):
      def __init__(self, name, age, language):  # 先继承，在重构
          Person.__init__(self, name, age)  # 继承父类的构造方法，也可以写成：super(Chinese,self).__init__(name,age)
          self.language = language  # 定义类的本身属性
          print("子类构造函数")
  
      def walk(self):
          print('is walking...')
  
  
  class American(Chinese):
      def __init__(self, name, age, language,height):
          Chinese.__init__(self,name,age,language)
          self.height=height
          print("孙类构造函数")
  
  
  c = American('bigberg', 22, 'Chinese',180)
