希望大家来指正一下，之前间断学习了很久，刚捡起来继续学习，下面的代码写的不太好，希望看到的大神能够给予指正。
修正版：
1 # python_zhangzengqiang 2 3 a = open("user.txt") 4 b = a.readlines() 5 a.close() 6 a2 = open("lock.txt") 7 b2 = a2.readlines() 8 a2.close() 9 loginsucess = False 10 while True: 11 username = input("请输入账号或输入'new'创建账号:").strip() 12 if username == "new": 13 while True: 14 newname = input("请输入账号:").strip() 15 if len(newname) != 0: 16 while True: 17 newpwd = input("请输入密码:").strip() 18 if len(newpwd) != 0: 19 a3 = open("user.txt","a") 20 a3.write(newname+" "+newpwd+"\n") 21 a3.close() 22 print("注册成功！") 23 exit() 24 else: 25 print("密码不能为空，请重新输入！") 26 continue 27 else: 28 print("账号不能为空，请重新输入！") 29 continue 30 for i2 in b2: 31 i2 = i2.split() 32 if username == i2[0]: 33 print("该账号已被锁定!") 34 exit() 35 if len(username) != 0: 36 for i in b: 37 i = i.split() 38 if username == i[0]: 39 for x in range(3): 40 password = input("请输入密码:").strip() 41 if password == i[1]: 42 loginsucess = True 43 break 44 else: 45 print("密码错误!") 46 else: 47 print("连续输入密码失败超过3次，账号已被锁定登录！") 48 a1 = open("lock.txt","a") 49 a1.write(username+"\n") 50 a1.close() 51 exit() 52 if loginsucess is True: 53 print("登录成功，欢迎回家！") 54 break 55 elif loginsucess is False: 56 print("账号错误，请重新输入！") 57 else: 58 print("账号错误，请重新输入！") 59 continue
