引发错误-字符串索引必须为整数

Question

#I did the same as you suggested the output at python shell is errors

from rauth import OAuth1Service

twitter = OAuth1Service(
    name='twitter',
    consumer_key='2Xs6nzIL8r5yx4DQCxgg',
    consumer_secret='XXXXXXXX',
    request_token_url='https://api.twitter.com/oauth/request_token',
    access_token_url='https://api.twitter.com/oauth/access_token',
    authorize_url='https://api.twitter.com/oauth/authorize',
    base_url='https://api.twitter.com/1/')

request_token, request_token_secret = twitter.get_request_token()

authorize_url = twitter.get_authorize_url(request_token)

print 'Visit this URL in your browser: ' + authorize_url
pin = raw_input('Enter PIN from browser: ')

session = twitter.get_auth_session(request_token,
                                   request_token_secret,
                                   method='POST',
                                   data={'oauth_verifier': pin})

params = {'screen_name': '@nytimes',  # User to pull Tweets from
          'include_rts': 1,         # Include retweets
          'count': 10}              # 10 tweets

r = session.get('statuses/user_timeline.json', params=params)

you asked for printing tweets only I did it here

for i, tweet in enumerate(r.json(), 1):
    print tweet
    #handle = tweet['user']['screen_name']
    #text = tweet['text']
    #print('{0}. @{1} - {2}'.format(i, handle, text))

Answer 1

Either your tweet is a str or your tweet is a dict and your tweet['user'] is a str . You seem to expect that tweet['user'] is a dict and try to index in that with tweet['user']['screen_name'] . This means that you are trying to index a str with another str which is not possible (as it makes no sense). The resulting error message states exactly that: TypeError: string indices must be integers .

I suppose you give out your tweet and your tweet['user'] (using print tweet and print tweet['user'] , but do not give out both in the same print statement, otherwise an error in the second expression will prevent the output at all) to figure out what the data structures are here. Then you probably know how to go on by yourself, or you post here again what you found out so we can go on helping.
