Python起步之学生信息管理系统

#编译环境为python3#学生信息管理系统包括基本的信息功能，能够实现学生信息的输入，查询，增添和删除#基本框架：开始操作菜单，接收输入选项，调用相应的函数实现对应的功能，循环回到开始菜单，#操作菜单：student = []def studentMeau():print('-'*30)print('-------学生信息管理系统-------')print('       1、添加学生信息')print('       2、删除学生信息')print('       3、查询学生信息')print('       4、修改学生信息')print('       5、退出')print('-'*30)def appendStuInf():studentInf = {'Name':'','Id':'','Sex':'','Age':'','Project':''}studentInf['Name'] = input('请输入学生姓名：')studentInf['Id'] = input('请输入学生学号：')studentInf['Sex'] = input('请输入学生性别：')studentInf['Age'] = input('请输入学生年龄：')studentInf['Project'] = input('请输入学生专业：')student.append(studentInf)#print(student)def deleteStuInf():num = input('请输入要删除学生的学号：')#for i in range(len(student)):#if student[i]['Id'] == num:#student.remove(student[i])#breakfor stu_inf in student:if stu_inf['Id'] == num:student.remove(stu_inf)break#print(student)def inquireStuInf():flag = Falsenum = input('请输入要查询学生的学号：')for stu_inf in student:if stu_inf['Id'] == num:print('name: '+stu_inf['Name']+'\n')print('Id: '+stu_inf['Id']+'\n')print('Sex: '+stu_inf['Sex']+'\n')print('Age: '+stu_inf['Age']+'\n')print('Project: '+stu_inf['Project']+'\n')flag = Truebreakif flag == False:print('没有查询到该生的信息！')def modifyStuInf():num = input('请输入要修改学生的学号：')flag = Falsefor stu_inf in student:if stu_inf['Id'] == num:print('name: '+stu_inf['Name']+'\n')print('Id: '+stu_inf['Id']+'\n')print('Sex: '+stu_inf['Sex']+'\n')print('Age: '+stu_inf['Age']+'\n')print('Project: '+stu_inf['Project']+'\n')flag = Truebreakif flag == False:print('没有该生的信息！')returnprint('1:姓名 ---- 2:学号 ---- 3:性别 ---- 4:年龄 ---- 5:专业 ---- 6:退出'+'\n')while True:choice = int(input("请输入选项序号："))if choice == 1:stu_inf['Name'] = input('请重新输入姓名：')print('姓名已更正为：'+stu_inf['Name']+'\n')elif choice == 2:stu_inf['Id'] = input('请重新输入学号：')print('学号已更正为：'+stu_inf['Id']+'\n')elif choice == 3:stu_inf['Sex'] = input('请重新输入性别：')print('性别已更正为：'+stu_inf['Sex']+'\n')elif choice == 4:stu_inf['Age'] = input('请重新输入年龄：')print('年龄已更正为：'+stu_inf['Age']+'\n')elif choice == 5:stu_inf['Project'] = input('请重新输入专业：')print('专业已更正为：'+stu_inf['Project']+'\n')elif choice == 6:print('修改完毕！')breakelse:print('输入有误，不予执行!')while True:studentMeau()choice = int(input("请输入选项序号："))if choice == 1:#添加学生信息appendStuInf()elif choice == 2:#删除学生信息deleteStuInf()elif choice == 3:#查询学生信息inquireStuInf()elif choice == 4:#修改学生信息modifyStuInf()elif choice == 5:print('谢谢使用！')breakelse:print('输入有误，检查后重新输入！')
