1.增删改查haproxy.conf配置文件

1.查询输入：www.oldboy1.com

2.删除输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}

3.增加输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}

4.修改输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}

　修改之后：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}

实现代码

2.用户认证

　用户输入账号密码三次错误，程序终止

　如果三次都是同一用户错误，锁定用户

1.定义一个字典，用户每次错误向字典增加记录{name count},当用户输入错误3次退出时，      判断字典的值是否大于3，大于3写到锁定文件里

 alex      alex3417
 oldboy    oldboy110
 oldgirl   oldgirl110

账号 密码

 accounts = {}

 def lock_user(name):
     with open("lock_user", mode="r+", encoding="utf8") as f_lock:
         for line in f_lock:
             if line.strip().split()[0] == name:
                 print("Lock user")
                 exit()

 def lockd_user(**kwargs):
     with open("lock_user",mode="a+",encoding="utf8") as f_lockd_user:
         for key in kwargs:
             if kwargs[key] >2:
                  f_lockd_user.write(key + "\n")

 def check_user(name,passwd):
     with open("user",mode="r",encoding="utf8") as f_check:
         for line in f_check:
             if name == line.strip().split()[0]:
                 if passwd == line.strip().split()[1]:
                     print("Success")
                     exit()
                 else:
                     add_error(name)
                     return name
         return name

 def add_error(name):
     if accounts:
         if name in accounts:
             accounts[name] += 1
         else:
             accounts[name] = 1
     else:
         accounts[name] = 1

 def main():
     count = 0
     while True:
         name = input("input name: ")
         passwd = input("input passwd: ")
         lock_user(name)    #判断用户是否锁定
         name = check_user(name,passwd)       #判断用户
         count += 1
         if count > 2:
             lockd_user(**accounts)
             print("exit than three")
             break

 if __name__ == '__main__':
         main()

代码实现

1.猜年龄，最多输入三次

 count = 1
 age = 8
 while count <= 3:
     guess_age = int(input("please input your age: "))
     if guess_age == age:
         print("You're right")
         exit()
     elif count == 3:
         exit()
     else:
         print("try agin..")
         count = count + 1

代码

2.猜年龄 ，每隔3次，问他一下，还想不想继续玩，y,n

 count = 1
 age = 18
 while True:
     guess_age = int(input("please input your age: "))
     if guess_age == age:
         print("You're right")
         exit()
     elif (count % 3) == 0:
         count += 1
         play = input("do you want to paly{y|n}")
         if play == "y":
             continue
         else:
             exit()
     else:
         print("you're wrong")
         count +=1

代码实现

3.编写登陆接口 输入用户名密码 认证成功后显示欢迎信息 输错三次后锁定

accounts = {}

def lock_user(name):
    with open("lock_user", mode="r+", encoding="utf8") as f_lock:
        for line in f_lock:
            if line.strip().split()[0] == name:
                print("Lock user")
                exit()

def lockd_user(**kwargs):
    with open("lock_user",mode="a+",encoding="utf8") as f_lockd_user:
        for key in kwargs:
            if kwargs[key] >2:
                 f_lockd_user.write(key + "\n")

def check_user(name,passwd):
    with open("user",mode="r",encoding="utf8") as f_check:
        for line in f_check:
            if name == line.strip().split()[0]:
                if passwd == line.strip().split()[1]:
                    print("Success")
                    exit()
                else:
                    add_error(name)
                    return name
        return name

def add_error(name):
    if accounts:
        if name in accounts:
            accounts[name] += 1
        else:
            accounts[name] = 1
    else:
        accounts[name] = 1

def main():
    count = 0
    while True:
        name = input("input name: ")
        passwd = input("input passwd: ")
        lock_user(name)    #判断用户是否锁定
        name = check_user(name,passwd)       #判断用户
        count += 1
        if count > 2:
            lockd_user(**accounts)
            print("exit than three")
            break

if __name__ == '__main__':
        main()

用户登录，三次后锁定

4.跳出3层循环

 flag = True

 while flag:
     while flag:
         while flag:
             if 1 != 2:
                 flag = False

 print("come on")
 flag = False

 for i in range(10):

     print("爷爷好")

     for n in range(10):

         print("爸爸好")

         for k in range(10):

             print("孙子好")
             if k == 2:
                 flag = True
                 break
         if flag:
             break
     if flag:
         break

 print("come on")
