class Person:

self.name = name
self.age = age
self.sex = sex

def personInfo(self):
print("姓名:", self.name, "年龄:", self.age, "性别:", self.sex)

super().__init__(name, age, sex)
self.school = school

# 示例调用
p1 = Person("张三", 20, "男")
p1.personInfo()

s1 = Student("李四", 18, "女", "清华大学")
s1.personInfo()
s1.studentInfo()

class Person: def __init__(self, name, age, sex): self.name = name self.age = age self.sex = sex def getSex(self): return self.sex class Teacher(Person): def __init__(self, name, age, sex, course, salary): Person.__init__(self, name, age, sex) self.course = course self.salary = salary def getSex1(self): super().getSex() p1 = Teacher("Anna", 30, "woman", "English", 8000) print(p1.getSex1()) 为什么输出None

输出为None是因为在getSex1方法中没有返回任何值。当没有明确返回值时，默认返回None。你可以在getSex1方法中添加return语句来返回性别。例如：

class Teacher(Person):
    def __init__(self, name, age, sex, course, salary):
        Person.__init__(self, name, age, sex)
        self.course = course
        self.salary = salary
    
    def getSex1(self):
        return super().getSex()

p1 = Teacher("Anna", 30, "woman", "English", 8000)
print(p1.getSex1())

这样就会输出"woman"，表示性别为女性。

您的代码已经非常完整了，我只是注意到了两个小错误。首先，在学生类的构造函数中，您两次赋值了`self.xueyan`，第二次应该是`self.banji`。其次，在学生类的`personInfo`方法中，您打错了`xueyuan`的拼写，应该是`xueyuan`。以下是已经修正的代码：

class Person:
    def __init__(self, name, age, sex):
        self.name = name
        self.age = age
        self.sex = sex

    def personInfo(self):
        print("姓名：", self.name, "年龄：", self.age, "性别：", self.sex)

class Student(Person):
    def __init__(self, xueyuan, banji, name, age, sex):
        super().__init__(name, age, sex)
        self.xueyuan = xueyuan
        self.banji = banji

    def personInfo(self):
        super().personInfo()
        print("学院：", self.xueyuan, "班级：", self.banji)

class Teacher(Person):
    def __init__(self, collage, prefessional, name, age, sex):
        super().__init__(name, age, sex)
        self.collage = collage
        self.prefessional = prefessional

    def personInfo(self):
        super().personInfo()
        print("学院：", self.collage, "专业：", self.prefessional)

    def teachObj(self):
        return "今天讲了如何使用面对对象设计程序"

person = Person("卢本伟", 33, "男")
person.personInfo()

student = Student("现代信息产业学院", "计科火链2202", "蔡徐坤", 14, "男")
student.personInfo()

teacher = Teacher("现代信息产业学院", "智能阿里2202", "陈伟霆", 54, "男")
teacher.personInfo()
