day1作业脚本

1.编写登录接口：

- 输入用户名和密码

- 认证成功后显示欢迎信息

- 输错三次后锁定

 #!/usr/bin/env python
 # -*- coding:utf-8 -*-

 import sys,os

 dir = os.getcwd()

 Count = 0

 STATUS = True
 while STATUS:
     L_user = input("you username:").strip()
     with open(dir+"\lock.txt","r+") as f:
         for n in f.readlines():
             if L_user == n.strip("\n"):
                 print("username is lock!!!")
                 sys.exit()
     L_passwd = input("you passwd:")
     with open(dir+"\passwds.txt","r+") as f1:
         for line in f1.readlines():
             user,passd = line.strip("\n").split(":")
             if L_user == user and L_passwd ==passd:
                 print("Welcome to login successfully")
                 sys.exit()
         else:
             print("login faile")
     Count += 1
     if Count == 3:
         print("sorry ,then three time ,username lock!!!")
         with open(dir+"\lock.txt","a+") as f2:
             f2.write(L_user+"\n")
             STATUS = False

2.编写多级菜单

- 三级菜单

- 可依次进入子菜单

第一次写python脚本，因为没有学到函数，所以写的有点糙和繁琐，我用自己学到的知识来实现这些需求。大家也可试一试。

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import sys

meau = {
    "北京":{
        "通州":["梨园","果园","土桥"],
        "朝阳":["将台","望京","关庄"],
        "海淀":["色色","吸收","里是"]
    },
    "天津":{
        "滨海":["但是","分手","而是"],
        "光华":["厚爱","感觉","色鬼"],
        "经济":["回来","反对","沟通"]
    },
    "河北":{
        "邯郸":["是啊","在啊","怕看"],
        "邢台":["个是","的个","是和"],
        "保定":["先动","个他","不发"]
    },
}

Shi = []
Status = True
try:
    while Status:
        for k in meau:
            print(k)
        choose = input("b:back,q:quie,choose:")
        if choose in meau:
            Shi.append(meau)
            meau = meau[choose]
        elif choose == "b":
            if Shi:
                meau = Shi.pop()
        elif choose == "q":
            Status = False
　　　　  else:
　　　　　    print("input error")
except TypeError as e:
    print(choose)
