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(méi)錯(cuò)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(huì)報(bào)錯(cuò)啊
