报错如下
Traceback (most recent call last):
File "E:/pythonProject3/8/8.1.py", line 23, in <module>
stu = Student('张三', 20, '10001')
File "E:/pythonProject3/8/8.1.py", line 14, in __init__
super().__init__(name, age)
TypeError: object.__init__() takes exactly one argument (the instance to initialize)代码如下
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def info(self):
print(self.name, self.age)
class Student:
def __init__(self, name, age, stu_no):
super().__init__(name, age)
self.stu_no = stu_no
class Teacher:
def __init__(self, name, age, year):
super().__init__(name, age)
self.year = year
stu = Student('张三', 20, '10001')
teacher = Teacher('李四', 34, 10)
stu.info()在输入stu.info的时候显示没有这个类，不知道是因为什么原因导致没有继承到子类
继承是class 子类（父类）：
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def info(self):
print(self.name, self.age)
class Student(Person):
def __init__(self, name, age, stu_no):
super().__init__(name, age)
self.stu_no = stu_no
class Teacher(Person):
def __init__(self, name, age, year):
super().__init__(name, age)
self.year = year
stu = Student('张三', 20, '10001')
teacher = Teacher('李四', 34, 10)
stu.info()
print(stu.stu_no)
teacher.info()
print(teacher.year)也可以写成：
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def info(self):
print(self.name, self.age)
class Student(Person):
def __init__(self, name, age, stu_no):
super(Student, self).__init__(name, age)
self.stu_no = stu_no
class Teacher(Person):
def __init__(self, name, age, year):
super(Teacher, self).__init__(name, age)
self.year = year
stu = Student('张三', 20, '10001')
teacher = Teacher('李四', 34, 10)
stu.info()
print(stu.stu_no)
teacher.info()
print(teacher.year)
class Student:改为
class Student(Person):才是继承吧
