异常后恢复

Question

如何从异常中恢复并从打开的文件继续行字符串？我卡住了！

    try:
while True:
    with open('us.txt') as f:
        for user in f:
            for tweet in tweepy.Cursor(api.user_timeline, screen_name=user, ).items():
                print(tweet.user.screen_name)
                csvWriter.writerow(tweet.user.screen_name)
except tweepy.TweepError as e:
print(e.reason)
sys.exit()

Answer 1

如果您的（诚然有点令人困惑）问题是询问如何忽略异常，但仍从文件中的位置继续，您应该尝试保持 try: 和 except:块尽可能靠近有问题的行。

例如，如果 csvWriter.writerow(tweet.user.screen_name) 是失败的行，您可以这样做：

while True:
    with open('us.txt') as f:
        for user in f:
            for tweet in tweepy.Cursor(api.user_timeline, screen_name=user,).items():
                print(tweet.user.screen_name)
                try:
                    csvWriter.writerow(tweet.user.screen_name)
                except tweepy.TweepError as e:
                    print(e)

如果错误出现在 for tweet in tweepy.Cursor(... 行，您可以这样做：

while True:
    with open('us.txt') as f:
        for user in f:
            try:
                for tweet in tweepy.Cursor(api.user_timeline, screen_name=user,).items():
                    print(tweet.user.screen_name)
                    csvWriter.writerow(tweet.user.screen_name)
            except tweepy.TweepError as e:
                print(e)

希望对您有所帮助！
