# data.json 文件同目錄下 [ { "id": 1, "username": "zhangshan", "password": "123qwe", "lock": false }, { "id": 2, "username": "lisi", "password": "123qwe", "lock": false }, { "id": 3, "username": "wangwu", "password": "123qwe", "lock": false }]

import json # 引入模塊 count = 1 # 打開一個json文件data = open("./data.json", encoding='utf-8')# 轉換為python對象strJson = json.load(data)flag = FalselockFlag = Falsewhile count <= 3: username = input("請輸入用戶名:") password = input('請輸入密碼:') for user in strJson:  if username == user['username'] and password == user['password']:   if not user['lock']:    flag = True   else:    lockFlag = True   break if flag:  print('登錄成功!!')  break else:  print('賬號或密碼錯誤') count = count + 1# 輸出(注意多層結構)# print(strJson[0]['id'])# for item in strJson:#  print(item)
