通过load json文件读取json指定数据（基于python 3.6）

Posted 2020-10-29 Moucong

<--------json文件--------->
{
  "DCN":{
    "filename":"at0101.07422",
    "variable":"气温",
    "Highest_temp":"最高气温",
    "Lowest_temp":"最低气温"
  },
  "DMD":{
    "filename":"bp0101.07422",
    "variable":"气压",
    "Highest_pre":"最高气压",
    "Lowest_pre":"最低气压"
  },
  "DMY":{
    "filename":"hu0101.07422",
    "variable":"相对湿度",
    "Highest_h":"最大相对湿度",
    "Lowest_h":"最低相对湿度"
  }
