Python多繼承帶參數(shù)出現(xiàn)異常

1在學習python多繼承過程中出現(xiàn)了一個異常，實在是搞不清楚問題出在哪里，求大神解答

class People(object):
    def __init__(self,name,sex):
        self.name=name
        self.sex=sex
class Teacher(People):
    def __init__(self, name, sex, student):
        super(Teacher, self).__init__(name, sex)
        self.student=student
class Father(People):
    def __init__(self,name,sex,child):
        super(Father,self).__init__(name,sex)
        self.child=child
class Disen(Father,Teacher):
    def __init__(self,name,sex,child,student):
        super(Disen,self).__init__(name,sex,child)
        super(Disen,self).__init__(name,sex,student)
print(Disen.__mro__)
disen=Disen('disen_','male','judy','student1')

異常代碼
F:MypythonProjectvenvScriptspython.exe F:/MypythonProject/my_file.py F:/
(<class '__main__.Disen'>, <class '__main__.Father'>, <class '__main__.Teacher'>, <class '__main__.People'>, <class 'object'>)
Traceback (most recent call last):
File "F:/MypythonProject/my_file.py", line 185, in <module>

disen=Disen('disen_','male','judy','student1')

File "F:/MypythonProject/my_file.py", line 182, in init

super(Disen,self).__init__(name,sex,child)

File "F:/MypythonProject/my_file.py", line 178, in init

super(Father,self).__init__(name,sex)

TypeError: __init__() missing 1 required positional argument: 'student'
問題：
1在調試過程中，Disen類實例執(zhí)行構造函數(shù)時首先調用了Father類的構造函數(shù)，但是錯誤提示Father類缺少一個student屬性，這個屬性是定義在Teacher類中，實在搞不清楚，這個應該是我對鉆石繼承理解不了，希望大神能夠結合我的錯誤講解一下鉆石繼承的概念，謝謝

首先應該避免多重繼承、多級繼承，不然代碼質量大打折扣了。不妨了解一下 組件化編程 與 接口編程 相關知識。

在這個例子中，你可以顯式調用父類的 __init__() 方法，代替 super() ，如下

# -*- coding: utf-8 -*-
class People(object):
    def __init__(self, name, sex):
        self.name = name
        self.sex = sex


class Teacher(People):
    def __init__(self, name, sex, student):
        People.__init__(self, name, sex)
        self.student = student


class Father(People):
    def __init__(self, name, sex, child):
        People.__init__(self, name, sex)
        self.child = child


class Disen(Father, Teacher):
    def __init__(self, name, sex, child, student):
        Father.__init__(self, name, sex, child)
        Teacher.__init__(self, name, sex, student)


def test_class():
    # 使用 pytest 測試
    disen = Disen('李毅', '男', 'judy', 'student1')
    assert disen.name == '李毅'
    assert disen.sex == '男'
    assert disen.child == 'judy'
    assert disen.student == 'student1'
