1、编写登陆接口
README.txt
1、运行login.py
2、程序首先读取user.txt帐号信息和lock.txt被锁定帐号信息。 3、输入帐号，密码 4、判断：
如输入正确显示登录成功。
如输入帐号为锁定帐号，提示用户并退出。
如帐号名称或密码错误，可再重复输入2次，超过三次后退出程序。如果是系统账户将被锁定帐号写入lock.txt。
login.py
# 初始化账户字典，帐号锁定列表
userinfo = {} lockinfo = []
# 读取账户信息及锁定帐号信息 with open("user.txt", "r") as f1, open("lock.txt", "r") as f2: while True: line = f1.readline().strip("\n") if not line: break else: userinfo[line.split(":")[0]] = line.split(":")[1] while True: line = f2.readline().strip("\n") if not line: break else: lockinfo.append(line) # 对输入的帐号进行处理 lockflag = 0 while lockflag < 3: # 控制输入小于3次 lockflag += 1 user = input("your name:") passwd = input("your password:") if user in lockinfo: print("this is lock account!") break if user in userinfo: if passwd == userinfo[user]: print("login ok!") break else: print("password error!") continue else: print("user is erro!") continue else: with open("lock.txt", "a+") as f: f.write(user+‘\n‘) print("your account is be locked!")
