如何修复'在处理上述异常期间，发生了另一个异常：'Python出错？

Question

我正在尝试创建一个reddit bot来检查subreddit中的最新评论，如果评论包含错误引用，我希望机器人用实际报价回复。我的问题是，在我的机器人由于reddit超时等待几分钟后，等待结束后，它会抛出异常错误。

我试图让它一次只处理一个异常，通过制作一个exc变量，并将其设置为0或1，但这没有奏效。

这是我的代码（不包括识别信息）：

import praw
import re
import time
import os

reddit = praw.Reddit(client_id= 'id',
                     client_secret= 'secret',
                     user_agent='<console: reddit_bot: 0.0.1 (by /u/username)>',
                     username= 'username',
                     password= 'password'
                     )
if not os.path.isfile("comments_replied_to.txt"):
        comments_replied_to = []
else:
    with open("comments_replied_to.txt", "r") as f:
        comments_replied_to = f.read()
        comments_replied_to = comments_replied_to.split("\n")
        comments_replied_to = filter(None, comments_replied_to)


subreddit = reddit.subreddit('subreddit')
pos=0
exc = 0

keywords = [ 'Luke, I am your father', 'Do you feel lucky, punk?']


for comment in subreddit.stream.comments():
    for keyword in keywords:
        if keyword in comment.body and comment.id not in comments_replied_to and comment.author != 'thatotteraccount':
            print("String with " + keyword + " found in comment " + comment.id)
            if keyword == 'Luke, I am your father':
                if exc==0:
                    try:
                        comment.reply('* "No, I am your Father."')
                    except praw.exceptions.APIException as e:
                        exc=1
                        if (e.error_type == "RATELIMIT"):
                            delay = re.search("(\d+) minutes", e.message)

                            if delay:
                                delay_seconds = float(int(delay.group(1)) * 60)
                                time.sleep(delay_seconds)
                                comment.reply('* "No, I am your Father."')
                                exc=0
                            else:
                                delay = re.search("(\d+) seconds", e.message)
                                delay_seconds = float(delay.group(1))
                                time.sleep(delay_seconds)
                                comment.reply('* "No, I am your Father."')
                                exc=0

            if keyword == 'Do you feel lucky, punk?':
                if exc==0:
                    try:
                        comment.reply('* "Youve got to ask yourself one question: Do I feel lucky? Well, do ya punk?" ')
                    except praw.exceptions.APIException as e:
                        exc=1
                        if (e.error_type == "RATELIMIT"):
                            delay = re.search("(\d+) minutes?", e.message)

                            if delay:
                                delay_seconds = float(int(delay.group(1)) * 60)
                                time.sleep(delay_seconds)
                                comment.reply('* "Youve got to ask yourself one question: Do I feel lucky? Well, do ya punk?" ')
                                exc=0
                            else:
                                delay = re.search("(\d+) seconds", e.message)
                                delay_seconds = float(delay.group(1))
                                time.sleep(delay_seconds)
                                comment.reply('* "Youve got to ask yourself one question: Do I feel lucky? Well, do ya punk?" ')
                                exc=0
            print("Replied to comment" + comment.id)

            list(comments_replied_to).append(comment.id)
            with open ("comments_replied_to.txt", "a") as f:
                f.write(comment.id + "\n")

它抛出的错误是：

    File "C:\Users\Blaze\Desktop\reddit_bot2.py", line 56, in <module>
    comment.reply('* "Youve got to ask yourself one question: Do I feel lucky? Well, do ya punk?" ')

感谢所有的帮助，谢谢。

在我看来，你正在等待它告诉你等待的时间，但是Reddit还没有完成冷却。你可能应该在睡眠时间增加10-30秒。
