Question

我收到了来自DarkSky（天气API）的大量数据，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。我将如何从这些数据中获取"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"]))

这里解析的数据：

{
    'latitude': REMOVED,
    'longitude': REMOVED,
    'timezone': 'Europe/London',
    'daily': {
        'data': [{
            'time': 1568156400,

Answer 1

在数据数组中建立索引，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"]

Answer 2

那是因为数据是一个列表。您必须通过抓住第一个元素将字典从列表中移出。
