    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}}

    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
    1 alex      alex3417

3 oldgirl   oldgirl110

    1.猜年龄，最多输入三次

     1 count = 1
 2 age = 8
 3 while count <= 3:
 4     guess_age = int(input("please input your age: "))
 5     if guess_age == age:
 6         print("You're right")
 7         exit()
 8     elif count == 3:
 9         exit()
10     else:
11         print("try agin..")
12         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

     1 count = 1
 2 age = 18
 3 while True:
 4     guess_age = int(input("please input your age: "))
 5     if guess_age == age:
 6         print("You're right")
 7         exit()
 8     elif (count % 3) == 0:
 9         count += 1
10         play = input("do you want to paly{y|n}")
11         if play == "y":
12             continue
13         else:
14             exit()
15     else:
16         print("you're wrong")
17         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:

                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 + "
")




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

     1 flag = True
 2 
 3 while flag:
 4     while flag:
 5         while flag:
 6             if 1 != 2:
 7                 flag = False
 8                 
 9 
10 print("come on")
11 flag = False
12 
13 for i in range(10):
14 
15     print("爷爷好")
16 
17     for n in range(10):
18 
19         print("爸爸好")
20         
21         for k in range(10):
22 
23             print("孙子好")
24             if k == 2:
25                 flag = True
26                 break
27         if flag:
28             break
29     if flag:
30         break
31 
32 print("come on")
