如何使用Tweepy和Python遍历用户列表？

问题描述

在我的代码的第一部分中，我获得了20个在Tweet中使用过“ gym”一词的用户的列表。这部分工作正常。

在第二部分中，我试图使用在第一部分中获得的用户名，并获取他们最近的20条推文中的每条。

我当前拥有的代码没有运行任何错误，但是它肯定不会返回我在第一部分中获得的每个人的20条推文，它所做的只是从结果中返回最后一行第一部分。

下面是我的代码，如您所见，我试图将在第一部分“ tweets”中创建的列表用作第二部分中的id输入，并且尝试使用[2]只调用列表的第三列（用户名所在的位置）。

import tweepy
from tweepy import OAuthHandler
import pandas as pd

access_token = ''
access_token_secret = ''
consumer_key = ''
consumer_secret = ''

auth = tweepy.OAuthHandler(consumer_key,consumer_secret)
auth.set_access_token(access_token,access_token_secret)

api = tweepy.API(auth,wait_on_rate_limit=True,wait_on_rate_limit_notify=True)

tweets = []

count = 20

for tweet in tweepy.Cursor(api.search,q="gym"+'-filter:retweets',since='2020-02-08',tweet_mode='extended',lang='en').items(count):

    try:
        data = [tweet.full_text,tweet.user.screen_name]
        data = tuple(data)
        tweets.append(data)

    except tweepy.TweepError as e:
        print(e.reason)
        continue

    except StopIteration:
        break

df = pd.DataFrame(tweets,columns=['Tweet','@ Name'])

print(df)

new_tweets = []

username = tweets[1]
count = 20

for user in tweepy.Cursor(api.user_timeline,id=username,tweet_mode='extended').items(count):

    try:
        data = [tweet.full_text,tweet.user.screen_name]
        data = tuple(data)
        new_tweets.append(data)

    except tweepy.TweepError as e:
        print(e.reason)
        continue

    except StopIteration:
        break

df2 = pd.DataFrame(new_tweets,columns=['Tweets','@ Name'])

print(df2)

df2.to_csv('test3.csv')

这是我的输出：

非常感谢任何帮助。

解决方法

在第二个for循环中，您仍在使用第一个for循环的 tweet 变量。您应该使用 user 变量。

,

几件事：

1. 您不会遍历20个不同的用户名。您对其进行了硬编码，以仅使用1 username = tweets[1]。即使那样，它仍然是('tweetmessage','username')的元组，所以您希望将字符串放在那里的索引位置1，即'tweets[1][1]

2. 您要以user的方式进行迭代，然后调用tweet变量：

    for user in tweepy.Cursor(api.user_timeline,id=username,tweet_mode='extended').items(count):
   
        try:
            data = [user.full_text,user.user.screen_name]  #<-- correct
            #data = [tweet.full_text,tweet.user.screen_name]  #<-- incorrect
            ...
   

完整代码：

import tweepy
from tweepy import OAuthHandler
import pandas as pd

access_token = ''
access_token_secret = ''
consumer_key = ''
consumer_secret = ''

auth = tweepy.OAuthHandler(consumer_key,consumer_secret)
auth.set_access_token(access_token,access_token_secret)

api = tweepy.API(auth,wait_on_rate_limit=True,wait_on_rate_limit_notify=True)

tweets = []

count = 20

for tweet in tweepy.Cursor(api.search,q="gym"+'-filter:retweets',since='2020-02-08',tweet_mode='extended',lang='en').items(count):

    try:
        data = [tweet.full_text,tweet.user.screen_name]
        data = tuple(data)
        tweets.append(data)

    except tweepy.TweepError as e:
        print(e.reason)
        continue

    except StopIteration:
        break

df = pd.DataFrame(tweets,columns=['Tweet','@ Name'])

print(df)

new_tweets = []
count = 20
for tweet,username in tweets:
    for user in tweepy.Cursor(api.user_timeline,tweet_mode='extended').items(count):
    
        try:
            data = [user.full_text,user.user.screen_name]
            data = tuple(data)
            new_tweets.append(data)
    
        except tweepy.TweepError as e:
            print(e.reason)
            continue
    
        except StopIteration:
            break

df2 = pd.DataFrame(new_tweets,columns=['Tweets','@ Name'])

print(df2)

df2.to_csv('test3.csv')
