用户管理系统
1.注册新用户如果注册用户已经存在,则报错
需要填写信息: name, passwd, gender, email,age2.用户登录 要求同之前写的用户登录系统3.注销用户 用户注销时,需要输入用户名和正确的用户密码4.显示用户信息 显示系统中存在所有已经注册用户的信息5.退出系统
代码如下
#!/usr/bin/env python#coding:utf-8info = """************************************************************用户登录管理系统************************************************************1. 注册新用户2. 用户登录3. 用户注销4. 用户信息显示5. 退出系统"""userinfo = {'root': {'name': 'root','password': 'redhat','gender': 1,'email': '','age': 12},}gender_choice = [0, 1, 2]def CreateUser():print "注册用户界面".center(50, '*')name = raw_input("*注册用户名:")if name in userinfo:print "用户已存在，请更换注册名"else:password = raw_input("*用户密码:")while True:gender = input("*性别(0-男 1-女 2-其他):")if gender in gender_choice:breakelse:print "请输入正确的选择"email = raw_input("用户邮箱:")if not email:email = Noneage = raw_input("年龄:")if not age:age = Noneelse:age = int(age)userinfo[name] = {'name': name,'password': password,'gender': gender,'email': email,'age':age,}print "%s 用户注册成功!!!" % (name)def UserLogin():print "用户登录界面".center(50, '*')trycount = 0while trycount < 3:name = raw_input("登录用户名：")if name not in userinfo:print "用户未注册"breakpassword = raw_input("登录密码：")trycount += 1if password == userinfo[name]['password']:print "恭喜%s登录成功" % (name)breakelse:print "请输入正确的用户名或密码！"else:print "已登录三次，请稍后再试"def DeleteUser():print "用户注销界面".center(50, '*')name = raw_input("注销用户名：")if name not in userinfo:print "用户未注册"else:password = raw_input("登录密码：")if password == userinfo[name]['password']:userinfo.pop(name)print "恭喜注销%s成功" % (name)def UserInfo():for key, value in userinfo.items():print "用户:%s" % (key),print "性别:%d" % (value['gender']),print "邮箱:%s" % (value['email']),print "年龄:%s" % (value['age']),print "\n\n"def main():while True:print infochoice = raw_input("Choice:").strip()if choice == "1":CreateUser()elif choice == "2":UserLogin()elif choice == "3":DeleteUser()elif choice == "4":UserInfo()elif choice == "5":exit()else:print "输入正确的选择"main()
