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,age1)
        Test1.__init__(self,university1)


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

我找到了一个解决方案-这仅依赖于使用super函数初始化所有（父类）属性。

   class Test:

        def __init__(self,age,**kwargs):
            self.name = name
            self.age = age
            super().__init__(**kwargs)

    class Test1:

        def __init__(self,university,**kwargs):
            self.school = school
            self.university = university
            super().__init__(**kwargs)

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

    class Test2(Test,Test1):

        def __init__(self,university1,**kwargs):
            kwargs['name'] = name1
            kwargs['age'] = age1
            kwargs['school'] = school1
            kwargs['university'] = university1
            super().__init__(**kwargs)

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