我使用循环下载了超过twitter的速率上限;但是,当我尝试附加列表时,它返回一个空数据帧
我的函数如下所示:
在:
import pandas as pd
import numpy as np
import tweepy
from datetime import timedelta
def get_tweets(handle):
batch_count_for_tweet_downloads = 200
try:
alltweets = []
tweets = api_twitter.user_timeline(screen_name=handle,
count=batch_count_for_tweet_downloads,
exclude_replies=True,
include_rts=False,
lang="en",
tweet_mode="extended")
# ---GET MORE THAN 200 TWEETS
alltweets.extend(tweets)
oldest = alltweets[-1].id - 1
oldest_datetime = pd.to_datetime(str(pd.to_datetime(oldest))[:-10]).strftime("%Y-%m-%d %H:%M:%S")
print(f"Getting Tweets For " + handle + ", After: " + oldest_datetime)
while len(tweets) > 0:
tweets = api_twitter.user_timeline(screen_name=handle, count=batch_count_for_tweet_downloads, max_id=oldest)
alltweets.extend(tweets)
oldest = alltweets[-1].id - 1
print("Count: " + f"...{len(alltweets)} " + handle + " Tweets Downloaded")
#---
df = pd.DataFrame(data=[tweets.user.screen_name for tweets in alltweets], columns=['Handle'])
df['Tweets'] = np.array([tweets.full_text for tweets in alltweets])
df['Date'] = np.array([tweets.created_at - timedelta(hours=4) for tweets in alltweets])
df['Len'] = np.array([len(tweets.full_text) for tweets in alltweets])
df['Like_count'] = np.array([tweets.favorite_count for tweets in alltweets])
df['RT_count'] = np.array([tweets.retweet_count for tweets in alltweets])
total_tweets.extend(alltweets)
print(handle + " Total Tweets Extracted: {}".format(len(alltweets)))
except:
pass
return df
正如您所看到的,我需要一些帮助来将循环合并到函数中
这样做的最佳方式是什么
提前谢谢你的帮助
编辑1:(我的代码现在看起来是什么样子)
在:
import tweepy
import pandas as pd
import numpy as np
from datetime import timedelta
handles = ['@MrML16419203', '@d00tn00t']
consumerKey = 'x'
consumerSecret = 'x'
accessToken = 'x'
accessTokenSecret = 'x'
authenticate = tweepy.OAuthHandler(consumerKey, consumerSecret)
authenticate.set_access_token(accessToken, accessTokenSecret)
api_twitter = tweepy.API(authenticate, wait_on_rate_limit=True)
total_tweets = []
def get_tweets(handle):
batch_count_for_tweet_downloads = 200
try:
alltweets = []
tweets = api_twitter.user_timeline(screen_name=handle,
count=batch_count_for_tweet_downloads,
exclude_replies=True,
include_rts=False,
lang="en",
tweet_mode="extended")
alltweets.extend(tweets)
oldest = alltweets[-1].id - 1
oldest_datetime = pd.to_datetime(str(pd.to_datetime(oldest))[:-10]).strftime("%Y-%m-%d %H:%M:%S")
print(f"Getting Tweets For " + handle + ", After: " + oldest_datetime)
while len(tweets) > 0:
tweets = api_twitter.user_timeline(screen_name=handle, count=batch_count_for_tweet_downloads, max_id=oldest)
alltweets.extend(tweets)
if len(alltweets) > 0:
oldest = alltweets[-1].id - 1
else:
pass
print("Count: " + f"...{len(alltweets)} " + handle + " Tweets Downloaded")
print('---Total Downloaded: ' + str(len(alltweets)) + ' for ' + handle + '---')
df = pd.DataFrame(data=[tweets.user.screen_name for tweets in alltweets], columns=['Handle'])
df['Tweets'] = np.array([tweets.full_text for tweets in alltweets])
df['Date'] = np.array([tweets.created_at - timedelta(hours=4) for tweets in alltweets])
df['Len'] = np.array([len(tweets.full_text) for tweets in alltweets])
df['Like_count'] = np.array([tweets.favorite_count for tweets in alltweets])
df['RT_count'] = np.array([tweets.retweet_count for tweets in alltweets])
print([tweets.favorite_count for tweets in alltweets])
print(np.array([tweets.favorite_count for tweets in alltweets]))
total_tweets.extend(alltweets)
print("----------Total Tweets Extracted: {}".format(df.shape[0]) + "----------")
except:
pass
return df
df = pd.DataFrame()
for handle in handles:
df_new = get_tweets(handle)
df = pd.concat((df, df_new))
print(df)
输出:

正如您可以看到的,对于少于200条tweet的句柄,数据帧会被填充。但是,不适用于包含200条以上tweet的句柄
对于任何一个偶然发现这一点的人,我让它发挥作用:
df=pd.DataFrame() 如果name='main': 对于句柄中的句柄: 获取推文(句柄) df=df.append(获取推文(句柄)) 打印(“-提取的推文总数:{}”。格式(df.shape[0])+“-”)
