python - 引发异常后继续执行循环

Question

for item in r.get_iterator():
    if 'retweeted_status' in item:
        print('aa')
    else:
        id_twitty = item['id']
        count_ret = item['retweet_count']

如果 item['id'] 抛出 KeyError 异常，则执行终止。

如何让for循环在异常发生后继续执行？

Answer 1

您可以 try catch 引发的 KeyError 异常，然后丢弃它:

for item in r.get_iterator():
    if 'retweeted_status' in item:
        print('aa')
    else:
        try:
            id_twitty = item['id']
            count_ret = item['retweet_count']
        except KeyError:
            pass
