Question

如何从异常中恢复并从打开的文件中继续行字符串？我被卡住了！

    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()

如果您（确实有点令人困惑）的问题是询问如何忽略该异常，但仍然继续您在文件中的位置，则应尝试将try:和except:块保留为接近问题线。

例如，如果csvWriter.writerow(tweet.user.screen_name)是失败的行，您可以执行以下操作：

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)

我希望这有帮助！
