翻译I have a python script that continuously stores tweets related to tracked keywords to a file. However, the script tends to crash repeatedly due to an error appended below. How do I edit the script so that it automatically restarts? I've seen numerous solutions including this (Restarting a program after exception) but I'm not sure how to implement it in my script.
import sys import tweepy import json import os consumer_key="" consumer_secret="" access_key = "" access_secret = "" auth = tweepy.OAuthHandler(consumer_key, consumer_secret) auth.set_access_token(access_key, access_secret) api = tweepy.API(auth) # directory that you want to save the json file os.chdir("C:\Users\json_files") # name of json file you want to create/open and append json to save_file = open("12may.json", 'a') class CustomStreamListener(tweepy.StreamListener): def __init__(self, api): self.api = api super(tweepy.StreamListener, self).__init__() # self.list_of_tweets = [] def on_data(self, tweet): print tweet save_file.write(str(tweet)) def on_error(self, status_code): print >> sys.stderr, 'Encountered error with status code:', status_code return True # Don't kill the stream print "Stream restarted" def on_timeout(self): print >> sys.stderr, 'Timeout...' return True # Don't kill the stream print "Stream restarted" sapi = tweepy.streaming.Stream(auth, CustomStreamListener(api)) sapi.filter(track=["test"])===========================================================================
