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"])

上面代码的问题在于它不断出现一条错误消息，指出// def on_error //行

出现意外的意外情况

您打开$array = array( 0 => 1, 1 => 3, 2 => 7, 3 => 0, 4 => 6, 5 => 3, );块而不捕获异常。

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

另外要小心，python区分大小写，因此try不是saveFile，saveFIle也不是saveFile.write() ...

按照以下方式编辑saveFile.Write()处理程序应该可以正常运行：

on_data()

修改：以下是您重新编写的完整代码：

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)

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