我想将推文存储为CSV，我使用了tweepy，并且设法将其存储在CVS中，但它只提取一天的数据。我想提取并存储一周的数据，而无需每天提取。
这就是我所做的：
def tweets_to_data_frame(public_tweets):
df = pd.DataFrame(data=[tweet.text for tweet in public_tweets], columns=['Tweets'])
df['len'] = np.array([len(tweet.text) for tweet in public_tweets])
df['date'] = np.array([tweet.created_at for tweet in public_tweets])
df['retweets'] = np.array([tweet.retweet_count for tweet in public_tweets])
df['lang'] = np.array([tweet.lang for tweet in public_tweets])
return df
public_tweet= api.search('donald trump')
df = tweets_to_data_frame(public_tweet)
df.to_csv('donaldtrump.csv')
df.head(15)
Tweets len date retweets lang

我想要的是一周的数据，
我的想法是：
def tweets_to_data_frame1(public_tweets):
for tweets in tweepy.Cursor(api.search,q = (public_tweets),count=100,
since = "2019-04-04",
until = "2019-04-07").items():
df = pd.DataFrame(data=[tweets.text for tweet in tweets], columns=['Tweets'])
df['len'] = np.array([len(tweets.text) for tweet in tweets])
df['date'] = np.array([tweets.created_at for tweet in tweets])
df['retweets'] = np.array([tweets.retweet_count for tweet in tweets])
df['lang'] = np.array([tweets.lang for tweet in tweets])
return df
df1 = tweets_to_data_frame1('donald trump')
错误：
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-24-96745c16c99c> in <module>
----> 1 df1 = tweets_to_data_frame1('donald trump')
<ipython-input-23-e5866a4adb3f> in tweets_to_data_frame1(public_tweets)
3 since = "2019-04-04",
4 until = "2019-04-07").items():
----> 5 df = pd.DataFrame(data=[tweets.text for tweet in tweets], columns=['Tweets'])
6
7 #df['id'] = np.array([tweet.id for tweet in tweets])
TypeError: 'Status' object is not iterable
预期结果：
Tweets len date retweets lang

但持续一周
答案 0 :(得分：0)
所以我想问题出在这里：
for tweets in tweepy.Cursor(api.search,q = (public_tweets),count=100,since = "2019-04-04",until = "2019-04-07").items():
tweepy.Cursor(...).items()是一个列表。因此，tweets变量的每个值都是一条推文。然后，您尝试使用列表推导，因此您尝试遍历该单个推文。这正是错误消息告诉您的内容。
相反，您可以做的是：
tweets = tweepy.Cursor(...).items()
df = pd.DataFrame(data=[tweet.text for tweet in tweets], columns=['Tweets'])
顺便说一句，我还要重命名public_tweets的{{1}}自变量
def tweets_to_data_frame1(public_tweets):参数在这种情况下只是一个搜索查询字符串，因此名称具有误导性
