python学习笔记 day23 作业---校园管理系统

1. 使用类实现一个校园管理系统

class School():
    def __init__(self,course):  # 一个学校同时开两门课应该怎么办，这里只能传一个course对象作为属性
        self.course=course  # course是Course类的对象
class Course():
    def __init__(self,name,period,price):
        self.name=name
        self.period=period
        self.price=price

class Class():  # 前面老师已经关联班级的情况下，班级怎么关联老师啊，
    def __init__(self,name,course):
        self.name=name
        self.course=course


class Student():
    def __init__(self,name,password,school,classes):
        self.name=name
        self.password=password
        self.school=school
        self.classes=classes

class Teacher():
    def __init__(self,name,password,school,classes,course):
        self.name=name
        self.password=password
        self.school=school
        self.classes=classes
        self.course=course




if __name__=='__main__':

    linux = Course('linux', '3 mon', 10000)
    python = Course('python', '2 mon', 20000)
    go = Course('go', '1 mon', '50000')

    beijing = School(python)
    shanghai = School(go)

    class_1 = Class('class_1', python)
    teacher_1 = Teacher('alex', '123', beijing, class_1, python)
    student_1 = Student('xuanxuan', '123', beijing, class_1)

    username=input(">>>")
    password=input(">>>")
    if username==student_1.name and password==student_1.password:
        print(student_1.school.course.name)
        print(student_1.classes.name)
    elif username==teacher_1.name and password==teacher_1.password:
        print(teacher_1.classes.name)
        print(teacher_1.course.name)
        # print("管理自己的班级功能有待完善")
    elif username=='Admin' and password=='Admin':

        class_2=Class('class_2', linux)
        teacher_2=Teacher('Eva-J', '123', beijing, class_2, linux)
        java = Course('Java', '4 mon', '10000')
        print('Admin创建的教师名字:', teacher_2.name)
        print('Admin创建的班级名字:',class_2.name)
        print('Admin创建的课程名字:', go.name)

    else:
        print('用户名或密码错误！')

运行结果：

学生视角登录：----查看课程，查看班级

教师视角登录： ----查看班级 课程：

管理员视角登录：----创建讲师，创建班级，创建课程

 

版本二（根据Eva-J的流程图来的）-----没有完成最后一步，把产生的数据使用Pickle写进文件，然后账号和密码我都是先调用Admin()来查找的

class School():
    def __init__(self,name,place,course_dict):
        self.name=name
        self.place=place
        self.course_dict=course_dict
class Teacher():
    def __init__(self,name,school,course,clas,students_dict):
        self.name=name
        self.school=school
        self.course=course    # 属性 course 是Course类的对象
        self.clas=clas        # clas 只是一个普通属性
        self.students_dict=students_dict
    def view(self):
        print("1: 查看自己讲的课程信息")
        print("2: 查看自己讲的班级")
        print("3: 查看自己带的学生")
        info=input(">>>")
        if info=='1':
            print(self.course.name)
        elif info=='2':
            print(self.clas)
        elif info=='3':
            for i in self.students_dict:
                print(self.students_dict[i].name)
        else:
            print("输入有误！")

class Course():
    def __init__(self,name,period,price):
        self.name=name
        self.period=period
        self.price=price

class Student():

        self.name=name

    def view(self):
        print("1: 选择自己的班级")
        print("2: 查看自己的信息")
        info=input('>>>')
        if info=='1':
            print(self.clas)
        elif info=='2':
            print(self.name)


class Admin():
    def __init__(self,name):
        self.name=name

        python = Course('python', '2 mon', 10000)
        linux = Course('linux', '3 mon', 20000)
        go = Course('go', '4 mon', 15000)
        course_dict_1 = {1: python, 2: linux}
        course_dict_2 = {1: go}

        beijing = School('希望小学', '北京', course_dict_1)
        shanghai = School('幸福小学', '上海', course_dict_2)

        self.student_1 = Student('璇璇', '1班', beijing)
        self.student_2 = Student('七七', '1班', beijing)
        self.student_3 = Student('脸脸', '2班', shanghai)
        self.student_4 = Student('猪猪', '2班', shanghai)
        students_dict_1 = {1: self.student_1, 2: self.student_2}
        students_dict_2 = {1: self.student_3, 2: self.student_4}

        self.alex = Teacher('alex', beijing, python, '1班', students_dict_1)
        self.Eva = Teacher('Eva-J', shanghai, go, '2班', students_dict_2)

if __name__=="__main__":
    username=input("username:")
    password=input("password:")
    if username=='admin' and password=='admin':
        admin = Admin("admin")
        print("欢迎您，%s" % admin.name)

    elif username=='璇璇' and password=='123':
        admin = Admin("admin")
        admin.student_1.view()


    elif username=='alex' and password=='123':
        admin = Admin("admin")
        admin.alex.view()

运行结果：
