Question

我正在使用OpenWeatherMap编写程序，并且具有有关天气的JSON文件：

是否有一种方法可以明确地保存"main":{"temp":...中的信息，或者我是唯一的保存方法？

{"coord":
    {"lon":145.77,"lat":-16.92},
    "weather":[{"id":803,"main":"Clouds","description":"broken clouds","icon":"04n"}],
    "base":"cmc stations",
    "main":{"temp":293.25,"pressure":1019,"humidity":83,"temp_min":289.82,"temp_max":295.37},
    "wind":{"speed":5.1,"deg":150},
    "clouds":{"all":75},
    "rain":{"3h":3},
    "dt":1435658272,
    "sys":{"type":1,"id":8166,"message":0.0166,"country":"AU","sunrise":1435610796,"sunset":1435650870},
    "id":2172797,
    "name":"Cairns",
    "cod":200}

代码：

response = resp.json()
if response['cod'] != '404':
    main_json = response['main']
    temperature = main_json['temp']

您明确是直接意思吗？

temperature = response['main']['temp']

编辑：

将json保存到名为data.json的文件后，以下代码在我的计算机上可以正常工作：

import json

with open('data.json') as json_file:
    response = json.load(json_file)

if response['cod'] != '404':
    main_json = response['main']['temp']

有没有一种方法可以显式调用json参数？
