【问题描述】:
我使用的数据是 Twitter API 的 Twitter 趋势主题。
url_0 = 'https://api.twitter.com/1.1/trends/place.json?id=2459115'
res = requests.get(url_0, auth=auth)
print(res, res.status_code, res.headers['content-type'])
print(res.url)
top_trends_twitter = res.json()
data= top_trends_twitter[0]
这是数据的样子:
[{'as_of': '2017-02-13T21:59:32Z',
'created_at': '2017-02-13T21:53:22Z',
'locations': [{'name': 'New York', 'woeid': 2459115}],
'trends': [{'name': 'Victor Cruz',
'promoted_content': None,
'query': '%22Victor+Cruz%22',
'tweet_volume': 45690,
'url': 'http://twitter.com/search?q=%22Victor+Cruz%22'},
{'name': '#percussion',
'promoted_content': None,
'query': '%23percussion',
'tweet_volume': None,
'url': 'http://twitter.com/search?q=%23percussion'}, .....etc
现在,我用 SQL 连接服务器并创建数据库和表后,出现错误。这是给我带来麻烦的部分:
for entry in data:
trendname = entry['trends']['name']
url = entry['trends']['url']
num_tweets = entry['trends']['trend_volume']
date= entry['as_of']
print("Inserting trend", trendname, "at", url)
query_parameters = (trendname, url, num_tweets, date)
cursor.execute(query_template, query_parameters)
con.commit()
cursor.close()
然后,我得到这个错误:
TypeError Traceback (most recent call last)
<ipython-input-112-da3e17aadce0> in <module>()
29
30 for entry in data:
---> 31 trendname = entry['trends']['name']
32 url = entry['trends']['url']
33 num_tweets = entry['trends']['trend_volume']
TypeError:字符串索引必须是整数
如何将字符串集放入字典中,以便将其用于输入数据代码?
