使用Tweepy提取推文一周

Question

I want to store tweets in CSV, I used tweepy and I managed to store it in CVS but it only extracts data for one day. I want to extract and store data for a week without needing to extract it every day.

This is what I have done:

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

What I want is the data for one week,

my idea is:

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')

error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

      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

expected results:

but for one week

Answer 1

So I guess the issue is here:

for tweets in tweepy.Cursor(api.search,q = (public_tweets),count=100,since = "2019-04-04",until = "2019-04-07").items():

tweepy.Cursor(...).items() is a list. So each value of tweets variable is a single tweet. And then you're trying to using list comprehension, so you are trying to iterate over that single tweet. That is exactly what error message told you.

What you could do instead would be something like:

tweets = tweepy.Cursor(...).items()
df = pd.DataFrame(data=[tweet.text for tweet in tweets], columns=['Tweets'])

BTW also I would rename public_tweets argument of def tweets_to_data_frame1(public_tweets):

public_tweets argument in this case is just a search query string so the name is misleading
