python模块与类与继承

我确实碰到了这个棘手的问题，不过我解决了。这个问题在一些python高手或是有经验的人来说，可能真不算是个问题，但是对于我这样子的初学者来说，着实难到了。

下面贴上代码

class SchoolMember(object):
    def __init__(self,name):
        self.name = name
        print "new a SchoolMember:%s" % self.name

    def tell(self):
        print "SchoolMember:%s" % self.name

class Teacher(SchoolMember):
    def __init__(self,name,salary):
        super(Teacher,self).__init__(name)
        self.salary = salary
        print "new a Teacher:%s,salary:%d" % (self.name,self.salary)

    def tell(self):
        print "Teacher:%s,salary:%d" % (self.name,self.salary)

class Student(SchoolMember):
    def __init__(self,name,score):
        super(Student,self).__init__(name)
        self.score = score
        print "new a Student:%s,score:%d" % (self.name,self.score)

    def tell(self):
        print "Student:%s,score:%d" % (self.name,self.score)

schoolMem = SchoolMember("Lily")
schoolMem.tell()
schoolMem = Teacher("LiLei",3000)
schoolMem.tell()
schoolMem = Student("HanMei",98)
schoolMem.tell()

以上代码段测试通过的。现在要用到模块，也就是要将以上三类进行封装

class SchoolMember(object):
    def __init__(self, name):
        self.name = name
        print "new SchoolMember:%s" % self.name
        
    def tell(self):
        print "School member:%s" % self.name

import SchoolMember

class Teacher(SchoolMember):
    def __init__(self, name, salary):
        super(Teacher, self).__init__(name)
        self.salary = salary
        
    def tell(self):
        print "teacher:%s,salary:%d" % (self.name, self.salary)
        
t = Teacher("Lily", 3000)
t.tell()

import SchoolMember
class Student(SchoolMember):
    def __init__(self, name, score):
        super(Student, self).__init__(name)
        self.score = score
        
    def tell(self):
        print "student:%s,score:%d" % (self.name, self.score)

测试模块：

import Teacher
import Student

teacher1 = Teacher("LiLei", 3000)
stu1 = Student("Lily", 98)

teacher1.tell()
stu1.tell()

分别执行以上4段代码，发现除了第1代码段，其余全错，错误：

Error when calling the metaclass bases

    module.__init__() takes at most x arguments (x+1 given)

错在SchoolMember为模块名，而继承类希望是类名，此时应该在class语句中的SchoolMember后加上.SchoolMember,即

class Teacher(SchoolMember.SchoolMember)

class Student(SchoolMember.SchoolMemeber)
