python 多个脚本
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

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):

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:

else:

def 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")
