建議檢查一下自己的代碼

class?Person(object):

????def?__init__(self,?name,?gender):

????????self.name?=?name

????????self.gender?=?gender

class?Student(Person):

????def?__init__(self,?name,?gender,?score):

????????super(Student,?self).__init__(name,?gender)

????????self.score?=?score

class?Teacher(Person):

????def?__init__(self,?name,?gender,?course):

????????super(Teacher,?self).__init__(name,?gender)

????????self.course?=?course

p?=?Person('Tim',?'Male')

s?=?Student('Bob',?'Male',?88)

t?=?Teacher('Alice',?'Female',?'English')

print(isinstance(p,?Person))

print(isinstance(p,?Student))

print(isinstance(p,?Teacher))

print(isinstance(p,?object))

t=Person('a','a')是沒錯的?

class Person:

? ? def __init__(self, name, gender):

? ? ? ? self.name = name

? ? ? ? self.gender = gender

? ? ? ??

class Student(Person):

? ? def __init__(self, name, gender, score):

? ? ? ? super(Student, self).__init__(name, gender)

? ? ? ? self.score = score

? ? ? ??

class Teacher(Person):

? ? def __init__(self, name, gender, subject):

? ? ? ? super(Teacher, self).__init__(name, gender)

? ? ? ? self.subject = subject

? ? ? ??

p = Person('Tim', 'male')

s = Student('Lily', 'Female', 88)

t = Teacher('Changyun', 'Female', 'English')

isinstance(t, Person)

isinstance(t, Teacher)

isinstance(t, Student)

print(isinstance(t, object))

不會報錯啊
