def __init__(self,name,age,sex):
self.name = name
self.age = age
self.sex = sex
self.enroll()
def enroll(self):
print('SchoolMember [%s] is enrolled!' % self.name)
SchoolMember.member_nums += 1
print('The [%s] school member [%s] is enrolled!' % (self.member_nums,self.name))
def tell(self):
print('Hello,my name is %s' %self.name)

class Teacher(SchoolMember):
def __init__(self,name,age,sex,course,salary):
super(Teacher,self).__init__(name,age,sex)   #继承
self.course = course
self.salary = salary
def teaching(self):
print('Teacher [%s] is teaching [%s]'%(self.name,self.course))

class Student(SchoolMember):
def __init__(self,name,age,sex,course,tuition):
super(Student,self).__init__(name,age,sex)
self.course = course
self.tuition = tuition
def pay_tuition(self):
print('NND,student [%s] pay tuition [%s]' %(self.name,self.tuition))

t1 = Teacher('Jef',22,'F','Py',1000)
t2 = Teacher('Jia',3,'F','JS',2000)

s1 = Student('Jingjing',27,'M','Travel',10000)
s2 = Student('Doudou',5,'N/A','Eat',100)

t1.tell()
t1.teaching()
s1.tell()
s1.pay_tuition()
