从praw到异步praw，现在得到"AttributeError：'coroutine‘对象没有属性’注释‘“

Question

我有一个小脚本正在运行，它应该从包含在下面的列表中的所有用户中提取所有评论：

import asyncpraw
import pandas as pd

reddit = asyncpraw.Reddit(
    user_agent = "XXX",
    client_id = "XXX",
    client_secret = "XXX",
    username = "XXX",
    password = "XXX"
)


dataset_one_author #(just a list of usernames)

body = []
author = []
created_utc = []
score = []
subreddit_id = []
permalink = []

count = 0


for index, row in dataset_one_author.iterrows():
    author_row = row['author']
   
    #try:
        
    count = count + 1
    print(count)

    for comment in reddit.redditor(author_row).comments.new(limit=None):
    
        body.append(comment.body)
        author.append(author_row)
        created_utc.append(comment.created_utc)
        score.append(comment.score)
        subreddit_id.append(comment.subreddit_id)
        permalink.append(comment.permalink)
     
        
            
    # except:
        
    #     body.append("user_deleted")
    #     author.append("user_deleted")
    #     created_utc.append("user_deleted")
    #     score.append("user_deleted")
    #     subreddit_id.append("user_deleted")
    #     permalink.append("user_deleted")
    #     #continue
        

a = pd.DataFrame(author, columns =['author'])
a['body'] = pd.DataFrame(body)
a['created_utc'] = pd.DataFrame(created_utc)
a['score'] = pd.DataFrame(score)
a['subreddit_id'] = pd.DataFrame(subreddit_id)
a['permalink'] = pd.DataFrame(permalink)

当我用普通的praw运行这个脚本时，它运行得很好(虽然非常慢)。按照建议，我改用了异步语言，现在我得到的是"AttributeError：'coroutine‘对象没有属性’注释‘。我知道我需要“等待”任务，但无法确定在哪里，任何帮助都是非常感谢的。如果您碰巧也发现了一个明显的性能问题，我也很高兴听到它。

(我已经注释掉了try/ out以获得异步errors错误--try/除这里通常是为了捕获来自已删除用户的404错误)。

听起来好像您还没有等待异步迭代器，所以

for comment in reddit.redditor(author_row).comments.new(limit=None):

试着做

async for comment in reddit.redditor(author_row).comments.new(limit=None):
