和上一篇随笔一样的要求，完善了一下老师接口和学生接口。
搞清楚了一件事情，就是import那么多文件，该怎么搞才比较方便。
1、先上文件目录
在lib中定义了各个类，一看名字就知道是啥类了哦
在interface中定义了接口程序，用户验证身份之后就调用相应的接口
在dumpfile中分了几个文件夹，是分别存放pickle的内容的
main就是主入口了
2、程序代码
main是程序入口，由用户输入选项，选择是学校管理员、老师、还是学生，对应调用interface包中的schoolcontrol、teachercontrol、studentcontrol函数。
1 #main.py
2 from interface import *
3 from lib import *
4
5 programexitflag=False
6 optdic={‘1‘:schoolmanage.schoolcontrol,‘2‘:teachermanage.teachercontrol,‘3‘:studentmanage.studentcontrol,‘4‘:exit}
7
8 while not programexitflag:
9 idcheck=input("Who are you?\n1:Administrator\n2:Teacher\n3:Student\n4:exit\n")
10 if idcheck in optdic.keys():
11 optdic[idcheck]()
schoolmanage.py是学校管理接口的程序。
1 from lib import *
2 import pickle
3 import os
4
5 def schoolcontrol():
6 print("This is school management view.")
7 schoolobj = School.School()
8
9 def chooseschool():
10 namein=input("请输入学校名字：")
11 fddir = os.path.dirname(os.path.dirname(__file__))
12 with open(‘%s/dumpfile/school/%s‘%(fddir,namein),‘rb‘) as fd:
13 schoolobj=pickle.load(fd)
14 schoolobj.getteacher()
15 schoolobj.getcourse()
16 schoolobj.getgroup()
17 schoolobj.getstudent()
18 return schoolobj
19
20 schoolmanageoptdic={‘1‘:schoolobj.setschool,‘2‘:chooseschool,‘3‘:schoolobj.addteacher,‘4‘:schoolobj.addcourse,‘5‘:schoolobj.addgroup,‘6‘:exit}
21 flag=True
22 while flag:
23 schoolmanopt=input("你要干什么？\n1：建校\n2：选择学校\n3：招聘老师\n4：开设课程\n5：开设班级\n6:退出\n")
24 if schoolmanopt in schoolmanageoptdic.keys():
25 schoolobj=schoolmanageoptdic[schoolmanopt]()
26 return
teachermanage是老师管理的程序
1 import os
2 import pickle
3 from lib import *
4
5 def teachercontrol():
6 print("This is teacher management view.")
7 teacherobj=Teacher.Teacher()
8
9 def slogin():
10 name=input("请输入您的名字：")
11 fddir = os.path.dirname(os.path.dirname(__file__))
12 with open(‘%s\dumpfile\\teacher\%s‘ % (fddir, name), ‘rb‘) as fd:
13 teacherobj=pickle.load(fd)
14 return teacherobj
15
16 teachermanageoptdic = {‘1‘: slogin(), ‘2‘:teacherobj.checkgroupinfo, ‘3‘:teacherobj.changescore,‘4‘:exit}
17 flag = True
18 while flag:
19 teachermanopt = input("你要干什么？\n1：登陆\n2：查看班级信息\n3：登记学生成绩\n4:退出\n")
20 if teachermanopt in teachermanageoptdic.keys():
21 teacherobj = teachermanageoptdic[teachermanopt]()
22 return
studentmanage.py是学生管理的程序
1 from lib import *
2 import pickle
3 import os
4
5 def studentcontrol():
6 print("This is student management view.")
7 studentobj=Student.Student()
8
9 def slogin():
10 name=input("请输入您的名字：")
11 fddir = os.path.dirname(os.path.dirname(__file__))
12 with open(‘%s\dumpfile\student\%s‘ % (fddir, name), ‘rb‘) as fd:
13 studentobj=pickle.load(fd)
14 return studentobj
15
16 studentmanageoptdic={‘1‘:studentobj.reg,‘2‘:slogin,‘3‘:studentobj.addgroup,‘4‘:studentobj.scorecheck,‘5‘:studentobj.pay,‘6‘:exit}
17 flag=True
18 while flag:
19 studentmanopt=input("你要干什么？\n1：注册\n2：登陆\n3：报名（选择要上的班级）\n4：查成绩\n5：缴费\n6:退出\n")
20 if studentmanopt in studentmanageoptdic.keys():
21 studentobj=studentmanageoptdic[studentmanopt]()
22 return
3、类统一都放在lib包中，在使用时只需要在__init__.py文件中，把lib包中所有类模块的名字加进去，然后在需要导入的文件中用from lib import *，在导入文件的程序中，先创建类对象实例，再用对象实例.属性（方法）的方法就可以使用类了。interface包也是一样处理。
