之前有一个关于选课的练习，一直没有给实现，趁着明天休息，琢磨一下给弄出来，本来以为今天能搞定，看来是我想多了。
先看一下文件分布吧
没啥可多说的，今天完成了一部分，剩下的明天搞定。
bin文件下：
import os,sys,logging,shelve BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.append(BASE_DIR) from conf import setting from core.main import Admin if __name__ == ‘__main__‘: Admin.run()
conf文件下的setting
import os,time,shelve,sys BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.append(BASE_DIR) from src.class_school import School data_path = os.path.join(BASE_DIR+‘\db‘) school_file =os.path.join(data_path,‘school‘)
core文件下的main
import os,sys,logging,shelve BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.append(BASE_DIR) from core.school_view import School_view from core.teacher_view import Teacher_view from coer.student_view import Student_view class Admin: def run(self): exit_flag = False menu = u‘‘‘ \033[32;1m 1.学生视图 2.老师视图 3.学校视图 4.退出\033[0m ‘‘‘ choice = { ‘1‘: Student_view , ‘2‘: School_view , ‘3‘: School_view , ‘4‘: exit() } while not exit_flag: print(menu) user_option = input(‘请输入你想进入的界面>>>‘) if user_option in choice: choice[user_option]() else: print(‘输入指令不正确！！！请重新输入！！！‘) if __name__ == ‘__main__‘: a = Admin() a.run()
core文件下的school_view
import os,sys,logging,shelve BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.append(BASE_DIR) from conf import setting from src.class_school import School class School_view: choice = { ‘1‘: ‘add_course‘, ‘2‘: ‘add_classroom‘, ‘3‘: ‘add_teacher‘, ‘4‘: ‘show_classroom‘, ‘5‘: ‘show_teacher‘, ‘6‘: ‘add_teacher‘, ‘7‘:exit() } def __init__(self): if os.path.exists(setting.school_file+‘.dat‘): self.school_file = shelve.open(setting.school_file) self.school_manger() self.school_file.close() else: print(‘没有学校和班级数据，请先进行创建‘) self.init_school() self.school_manger() self.school_file.close() def init_school(self): self.school_file = shelve.open(setting.school_file) self.school_file[‘北京‘] = School(‘总校‘,‘北京‘) self.school_file[‘上海‘] = School(‘总校‘,‘上海‘) def school_manger(self): while True: for school_name in self.school_file: print(‘学校名称是：%s‘%school_name) school_option = input(‘请输入需要管理的学校名称‘) if school_option in self.school_file: self.school_option = school_option self.school_obj = self.school_file[school_option] else: print(‘请重新输入！！！‘) # ‘‘‘ 如果是北京就等于self.school_obj[北京] # file[北京] =School(‘总校‘,‘北京‘) # 所以当下文出现了self.school_obj.school_course =School(‘总校‘,‘北京‘).school_course # 等同于调用了School().school_course的属性是 # ‘‘‘ while True: menu = ‘1.添加课程‘ ‘2.添加班级‘ ‘3.添加讲师‘ ‘4.查看班级、课程‘ ‘5.查看讲师 ‘ ‘6.修改讲师‘ ‘7.退出‘ print(‘欢迎来到Python学习%s校区‘%self.school_option) print(menu) user_choice = input(‘请选择你所需的功能>>>‘) if hasattr(self,choice[user_choice]): func = getattr(self,choice[user_choice]) else: print(‘指令输入错误。‘) pass def add_course(self): course_name = input(‘请输入课程名称>>>:‘).strip() course_price = input(‘请输入课程价格>>>:‘).strip() course_time = input(‘请输入课程周期[默认为周]>>>:‘).strip() if course_name in self.school_obj.school_course: print(‘课程已经存在‘) else: self.school_obj.create_course(course_name, course_price, course_time) # 相当于School.create_course(course_name, course_price, course_time) print(‘%s课程添加成功‘ % course_name) self.school_file.update({self.school_option: self.school_obj}) self.school_file.close() def add_classroom(self): class_name = input(‘请输入班级名称>>>:‘).strip() class_course = input(‘请输入课程>>>:‘).strip() if class_name not in self.school_obj.sch_class_room: # sch_class_room if class_name not in self.school_obj.school_course: course_obj = self.school_obj.school_course[class_course] self.school_obj.create_classroom(class_name, course_obj) self.school_file.update({self.school_option: self.school_obj}) self.school_file.close() print(‘班级创建成功‘) else: print(‘课程不存在‘) else: print(‘班级已经存在‘) def show_classroom(self): for classroom in self.school_obj.sch_class_room: class_obj = self.school_obj.sch_class_room[classroom] print(‘班级名称:%s\t课程:%s‘ % (class_obj.class_name, class_obj.course_obj.course_name)) def add_teacher(self): teacher_name = input(‘请输入讲师姓名>>>:‘) teacher_age = input(‘请输入讲师年龄>>>:‘) teacher_gender = input(‘请输入讲师性别>>>:‘) teacher_salary = input(‘请输入讲师薪水>>>:‘) class_name = input(‘请输入授课班级>>>:‘) if class_name in self.school_obj.sch_class_room: # sch_class_room class_obj = self.school_obj.sch_class_room[class_name] if teacher_name not in self.school_obj.sch_teacher: self.school_obj.create_teacher(teacher_name, teacher_age, teacher_gender, teacher_salary, class_name, class_obj) print(‘讲师创建成功,请确认是否已经签完合同‘) else: self.school_obj.modify_teacher({}) print(‘修改讲师成功‘) self.school_file.update({self.school_option: self.school_obj}) self.school_file.close() else: print(‘请先创建班级‘) def show_teacher(self): for teacher_name in self.school_obj.sch_teacher: teacher_obj = self.school_obj.sch_teacher[teacher_name] for t in teacher_obj.teacher_classroom: class_obj = self.school_obj.sch_class_room[t] stu_list = [] for j in class_obj.class_student: stu_list.append(j) print(‘教师姓名:%s\t教师所在班级:%s\t教授课程:%s\t课程学员:%s‘ % (teacher_obj.teacher_name , t, class_obj.course_obj.course_name, class_obj.class_student)) def exit(self): sys.exit(‘程序退出‘)
关于logging模块、shelve模块，基本忘的差不多了，现在内容逐渐多了，复习貌似更重要，不能过于激进，争取端午节前实现自己的承诺。
