Python中超函数的多重继承和用法

Question

class Test:

    def __init__(self, name, age):
        self.name = name
        self.age = age

class Test1:

    def __init__(self, school, university):
        self.school = school
        self.university = university

    def get(self):
        print('josh')

class Test2(Test,Test1):

    def __init__(self, name1, age1, school1, university1):
        super().__init__(name = name1, age = age1 , school = school1,  university = university1)


t = Test2('john', 16, 'Harvard', 'Yale')

为什么不能将值分配给父类属性？例如，对于上述课程，为什么我不能执行以下课程？

t.school # returns error 
t.university #returns error

但是，以下有效吗？

t.name
t.age

Answer 1

您必须为每个基类调用构造函数。请参见此处：

class Test:

    def __init__(self, name, age):
        self.name = name
        self.age = age

class Test1:

    def __init__(self, school, university):
        self.school = school
        self.university = university

    def get(self):
        print('josh')

class Test2(Test,Test1):

    def __init__(self, name1, age1, school1, university1):
        Test.__init__(self, name1, age1)
        Test1.__init__(self, school1, university1)


t = Test2('john', 16, 'Harvard', 'Yale')
print(t.name)
print(t.age)
print(t.school)
print(t.university)
