在解释super() 之前,我们首先需要了解多重继承的概念。
多重继承:意味着一个子类可以继承多个父类。
在以下示例中,子类从父类继承了属性方法。
class Father: fathername = "" def father(self): print(self.fathername) class Mother: mothername = "" def mother(self): print(self.mothername) class Child(Father, Mother): def parent(self): print("Father :", self.fathername) print("Mother :", self.mothername) s1 = Child()s1.fathername = "Srinivas" s1.mothername = "Anjali" s1.parent()
输出结果
Father : Srinivas Mother : Anjali
在下面的示例中,显示了(即) super()具有多个继承
super() :super函数可用于替换对的显式调用
class Father: fathername = "" def father(self): print(self.fathername) class Mother: mothername = "" def mother(self): print(self.mothername) class Child(Father, Mother): def parent(self): super().__init__() print("i am here") print("Father :", self.fathername) print("Mother :", self.mothername) s1 = Child()s1.fathername = "Srinivas" s1.mothername = "Anjali" s1.parent()
当您运行程序时,输出将是
输出结果
i am here Father : Srinivas Mother : Anjali
