读取本地json文件,解析json(实例讲解)

# data.json 文件同目录下 [ { "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 # 引入模块 count = 1 # 打开一个json文件data = open("./data.json", encoding='utf-8')# 转换为python对象strJson = json.load(data)flag = FalselockFlag = Falsewhile count <= 3: username = input("请输入用户名:") password = input('请输入密码:') 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('登录成功!!')  break else:  print('账号或密码错误') count = count + 1# 输出(注意多层结构)# print(strJson[0]['id'])# for item in strJson:#  print(item)
