Twython - 爲什麼我會得到一個關鍵錯誤？

Question

爲什麼我得到一個關鍵錯誤？ 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是一個頂層收集結果;它包含兩個鍵：search_metadata和一個statuses列表。後者是一個序列;即使與count=1你仍然需要索引結果。

每條推文follows a set structure;如果你想拿到張貼鳴叫用戶的網名，看'user'關鍵，它有一個'screen_name'鍵：

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

它總是幫助看到一個交互式的Python會話結果：

>>> 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'])

>>> len(search_results['statuses'])

Answer 2

修改print聲明如下：

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