python学生信息管理系统
本文实例为大家分享了python学生信息管理系统的具体代码,供大家参考,具体内容如下
#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]) # break for stu_inf in student: if stu_inf['Id'] == num: student.remove(stu_inf) break # print(student) def inquireStuInf(): flag = False num = 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 = True break if 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 = False 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 = True break if flag == False: print('没有该生的信息!') return print('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!') break else: 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!') break else: print('输入有误,检查后重新输入!')
