Python Twitter API流tweepy试图将数据保存到CSV文件

Question

from tweepy import Stream 
from tweepy import OAuthHandler 
from tweepy.streaming import StreamListener 

ckey = 'hidden due to question' 
csecret = 'hidden due to question' 
atoken = 'hidden due to question' 
asecret = 'hidden due to question' 

class listener(StreamListener): 

    def on_data(self, data): 
     try: 
      print (data) 
      saveFile = open('TwitterAPI.csv','a') 
      saveFile.write(data) 
      saveFile.Write('\n') 
      saveFIle.close() 
      return (True) 
    def on_error(self, status): 
     print (status) 

auth = OAuthHandler(ckey, csecret) 
auth.set_access_token(atoken, asecret) 
twitterStream = Stream(auth, listener()) 
twitterStream.filter(track=["car"]) 

上面的代码的问题是，它一直在提出一个错误消息，指出有一个意外的unindent在//def on_error // row

Answer 1

您打开一个try块，但没有捕捉到异常。

https://docs.python.org/3/tutorial/errors.html

另外要小心，蟒蛇是大小写敏感的，所以saveFile不saveFIle，也不saveFile.write()是saveFile.Write() ...

编辑您的on_data()处理程序如下应该使其工作：

def on_data(self, data): 
    try: 
     print(data) 
     with open('TwitterAPI.csv','a') as f: 
      f.write(data) 
    except Exception as e: # here catch whatever exception you may have. 
     print('[!] Error : %s' % e) 

编辑：以下是您完整的代码修改：

from tweepy import Stream 
from tweepy import OAuthHandler 
from tweepy.streaming import StreamListener 

ckey = 'hidden due to question' 
csecret = 'hidden due to question' 
atoken = 'hidden due to question' 
asecret = 'hidden due to question' 


class listener(StreamListener): 

    def on_data(self, data): 
     try: 
      print(data) 
      with open('TwitterAPI.csv','a') as f: 
       f.write(data) 
     except: 
      pass 

    def on_error(self, status): 
     print (status) 

auth = OAuthHandler(ckey, csecret) 
auth.set_access_token(atoken, asecret) 
twitterStream = Stream(auth, listener()) 
twitterStream.filter(track=["car"])
