如何从JSON数据中解析数据？

Question

我从 DarkSky 收到了大量数据（天气 API），我想获取 "summary" 的值。

它应该是 JSON 格式，然后我将其翻译成字典。但是，python 将 "data" 识别为列表，而不是字典。我将如何从该数据中获取 "summary" 的值？

darkSkyURL ="https://api.darksky.net/forecast/###Key has Been Removed###/{},{},{}?exclude=minutely,currently,flags,hourly".format(latitude, longitude, unixTime) #creates appropriate url, using known Long, Lang and current epoch time. These values are formatted into the url
darkSkyReport = requests.get(darkSkyURL)
darkSkyData = darkSkyReport.json()
print(darkSkyData["daily"]["data"]["summary"]))

解析后的数据如下：

{
    'latitude': REMOVED,
    'longitude': REMOVED,
    'timezone': 'Europe/London',
    'daily': {
        'data': [{

数据数组中的索引然后加载摘要对象

darkSkyURL ="https://api.darksky.net/forecast/###Key has Been Removed###/{},{},{}?exclude=minutely,currently,flags,hourly".format(latitude, longitude, unixTime) #creates appropriate url, using known Long, Lang and current epoch time. These values are formatted into the url
darkSkyReport = requests.get(darkSkyURL)
darkSkyData = darkSkyReport.json()
summary = darkSkyData["daily"]["data"][0]["summary"]
