Twython-為什么會出現關鍵錯誤？

Question

為什么會出現關鍵錯誤？ 如何打印screen_name？

from twython import Twython

CONSUMER_KEY = "123"
CONSUMER_SECRET = "123"
OAUTH_TOKEN = "123"
OAUTH_TOKEN_SECRET = "123"
twitter = Twython(CONSUMER_KEY, CONSUMER_SECRET, OAUTH_TOKEN,OAUTH_TOKEN_SECRET)

search_results = twitter.search(q='funny', count=1)

print(search_results["screen_name"])

Answer 1

search_results是頂級收集結果； 它包含兩個鍵： search_metadata和statuses列表。 后者是一個序列； 即使count=1您仍然需要對該結果建立索引 。

每條推文遵循一個固定的結構 ; 如果要獲取發布該推文的用戶的屏幕名稱，請查看'user'鍵，它具有'screen_name'鍵：

print(search_results['statuses'][0]['user']['screen_name'])

它總是有助於在交互式Python會話中查看結果：

>>> search_results = twitter.search(q='funny', count=1)
>>> type(search_results)
<class 'dict'>
>>> search_results.keys()
dict_keys(['search_metadata', 'statuses'])
>>> type(search_results['search_metadata'])
<class 'dict'>
>>> type(search_results['statuses'])
<class 'list'>
>>> from pprint import pprint
>>> pprint(search_results['search_metadata'])

Answer 2

修改print語句，如下所示：

print(search_results["user"]["screen_name"])
