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("
"):
                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("
").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+"
")
            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)
