python自动化运维之路~DAY1

Posted 2020-08-22

刚学python，有大神给指点指点的吗？

 

#!/usr/bin/env python
#_*_coding:utf8_*_
import getpass,sys
count = 0
match_info = False #用布尔值来标志用户密码是否匹配，默认是flase
while count < 3:
    username = input("\\033[32;1mAsk you for a username ：\\033[0m")
    with open("locked.txt",‘r‘,encoding="utf-8") as lock_check:
        for lock in lock_check.readlines():
            lock = lock.split()
            type (username)
            type (lock)
            if username == lock[0]:
                sys.exit(‘\\033[31;1mSorry, the current user has been locked, please contact the administrator!\\033[0m‘)
    password = input(‘\\033[32;1mAsk you for a password :\\033[0m‘)
    #password = getpass.getpass(‘\\033[32;1mAsk you for a password :\\033[0m‘)
    with  open("user_info.txt",‘r‘,encoding="utf-8") as user_check:
        for line in user_check.readlines():
             user,passwd = line.strip(‘\\n‘).split()
             if username == user and password == passwd:
                match_info = True
                print("You are welcome to use this system", username)
                sys.exit()
    if match_info == False:
        print("The account information you entered is not valid. Please re-enter it and enter the three error to lock the user.")
        count += 1
    else:
        print("You are welcome to use this system", username)
else:
    print("Sorry, the user you entered has been locked.")
    f = open("locked.txt","a",encoding="utf-8")
    f.write(username )
    f.close()

运行这个代码之前，要在代码的目录下新建locked.txt和user_info.txt在能执行的哟~

怎么才能把换行符写上去啊~我试过了好多次，都无法将换行符加上去呢~在线等大神指点啊
