Question

不确定如何解决这个问题？请指导：

import praw

r = praw.Reddit(user_agent="getting top posts from a subredit and its submissions", site_name='lamiastella')
subreddit = r.get_subreddit('iama')
top_year_subreddit = subreddit.get_top_from_year
submissions = top_year_subreddit(limit=50)
for submission in submissions:
    #submission.replace_more_comments(limit=None, threshold=0)
    all_comments = praw.helpers.flatten_tree(submission.comments)
    all_comments.sort(key = lambda comment : comment.score, reverse = True)
    top_comments = all_comments[:30]
    for comment in top_comments:
        print(comment.body)

错误是：

$ python getSubmissionsFromSubreddit.py 
Traceback (most recent call last):
  File "getSubmissionsFromSubreddit.py", line 10, in <module>
    all_comments.sort(key = lambda comment : comment.score, reverse = True)
  File "getSubmissionsFromSubreddit.py", line 10, in <lambda>
    all_comments.sort(key = lambda comment : comment.score, reverse = True)
  File "/usr/local/lib/python2.7/dist-packages/praw/objects.py", line 92, in __getattr__
    raise AttributeError(msg)
AttributeError: '<class 'praw.objects.MoreComments'>' has no attribute 'score'

我将我的代码更新为此，但仍然会收到检索热门评论的错误：

import praw

subreddit_name = 'nostalgia'
num_submissions = 2
r = praw.Reddit(user_agent="getting top posts from a subredit and its submissions", site_name='lamiastella')
subreddit = r.get_subreddit(subreddit_name)
top_submissions = subreddit.get_top_from_year(limit = num_submissions, comment_sort='top')
for submission in top_submissions:
        submission.replace_more_comments(limit=None, threshold=0)
        all_comments = praw.helpers.flatten_tree(submission.comments)
        if len(all_comments) > 100:
                print(len(all_comments))
                top_comments = all_comments.sort(key = lambda comment : comment.score, reverse = True)
                for comment in top_comments[:10]:
                        print(comment.body)
        else:
                continue

我收到此错误：

148
Traceback (most recent call last):
  File "getSubmissionsFromSubreddit.py", line 14, in <module>
    for comment in top_comments[:10]:
TypeError: 'NoneType' object has no attribute '__getitem__'

Answer 1

这是正确答案：

import praw

subreddit_name = 'nostalgia'
num_submissions = 2
num_top_comments = 10
num_comments_per_submission = 500
r = praw.Reddit(user_agent="getting top posts from a subredit and its submissions", site_name='lamiastella')
subreddit = r.get_subreddit(subreddit_name)
top_submissions = subreddit.get_top_from_year(limit = num_submissions, comment_limit=num_comments_per_submission, comment_sort='top')
for submission in top_submissions:
        submission.replace_more_comments(limit=None, threshold=0)
        all_comments = praw.helpers.flatten_tree(submission.comments)
        if len(all_comments) > 100:
                print(len(all_comments))
                top_comments = sorted(all_comments, key=lambda comment: -comment.score)
                for comment in top_comments[:10]:
                        print(comment.body)
                        if comment.author != None:
                                print('{0}: {1}'.format('Author name', comment.author.name))
                        else:
                                print('Author account is DELETED')
                        print('{0}: {1}'.format('Comment score is', comment.score))
        else:
                continue

AttributeError：'<class'praw.objects.morecomments'=“”>'没有属性'得分'
