在 Python 中使用 Praw 获取 Reddit 评论的子评论

Question

我正在使用 praw 从 reddit 线程中抓取信息。我可以使用 r.get_submission(thread).comments 给我一个线程中的所有评论，但现在我想遍历所有这些评论并获取子评论。

这是我拥有的：

r = praw.Reddit(user_agent="archiver v 1.0")
thread = "https://www.reddit.com/r/AskReddit/comments/4h4o7s/what_do_you_regret_doing_at_university/"
r.login(settings['username'], settings['password'], disable_warning=True)
submission = r.get_submission(thread)

for comment in submission.comments:
    #this works, prints out the comments text
    print(comment.body)

    #now i want to get the child comments that are replied to this comment
    commentSubmission = r.get_submission(comment.permalink)
    #ideally comments[0] should show me first reply, comments[1] the second. etc
    print(commentSubmission.comments[1])

这会引发 IndexError: list index out of range。我正在使用尝试将评论作为提交的方法，因为它类似于我在研究时在这里看到的解决方案 https://www.reddit.com/r/redditdev/comments/1kxd1n/how_can_i_get_the_replies_to_a_comment_with_praw/

我的问题是：给定一个 praw comment 对象，我如何遍历所有作为回复的子评论？我想获取所有直接回复另一个评论对象的评论

例如，在我程序的示例线程中，第一条评论是Not going out freshman year我想得到像Meh, I never went out at all in college.和Your story sounds identical to mine

这样的回复评论

Answer 1

它和comment.replies一样简单，它returns和submission.comments同种可迭代的Comment和MoreComments对象，后者为更多同级评论。

一些示例代码：

submission = r.get_submission(thread)
process_comments(submission.comments)

def process_comments(objects):
    for object in objects:
        if type(object).__name__ == "Comment":
            process_comments(object.replies) # Get replies of comment

            # Do stuff with comment (object)

        elif type(object).__name__ == "MoreComments":
            process_comments(object.comments()) # Get more comments at same level
