Python:TypeError: 'Comment' 类型的参数不可迭代

Question

我正在尝试编写一个简单的 reddit 机器人，它将进入 subreddit，进入提交，阅读评论，如果评论说“感觉”，它会发布感觉 gif。我得到这个错误:'TypeError: argument of type 'Comment' is not iterable' when trying to do has_feels = 'feels' in comment.

我的代码:

import praw
import time

r = praw.Reddit('Posts Feels gif in response to someone saying feels'
                'by: Mjone77')
r.login('Feels_Bot', 'notrealpassword')
already_done = []

feels = ['feels']
while True:
    subreddit = r.get_subreddit('bottest')
    for submission in subreddit.get_new(limit=10):
        #submission = next(submissions)
        commentNum = 0
        for comment in submission.comments:
            print(comment)
            print(comment.id)
            has_feels = 'feels' in comment
            if comment.id not in already_done and has_feels:
                #comment.reply('[Relevant](http://i.imgur.com/pXBrf.gif)')
                already_done.append(comment.id)
                print('Commented')
        time.sleep(1800)

错误报告(前两行是代码的打印输出，直到它中断):

The feels are strong

Traceback (most recent call last):
  File "C:\Users\Me\Desktop\My Programs\Feels Bot\Feels Bot\FeelsBot.py", line 18, in <module>
    has_feels = 'feels' in comment

sys:1: ResourceWarning: unclosed <socket object at 0x0369D8E8>
C:\Python34\lib\importlib\_bootstrap.py:2150: ImportWarning: sys.meta_path is empty

任何人都知道如何解决这个问题，所以如果评论在其中某处包含“感觉”，它会将 has_feels 设置为 true 吗？

此外，一旦它确实处理了提交中的所有评论，它就会停止，不会进入下一次提交。任何人都知道如何解决这个问题？如果您现在还不知道，请不要费心为我查找任何内容，我可以找到那部分内容。

has_feels = 'feels' in comment

comment 看起来是一个对象，其属性本质上不像 list 或 string 那样可迭代。

From the praw documentation ，您需要通过 body 属性访问评论的文本:

所以像这样:

has_feels = 'feels' in comment.body

以下是一些关于为什么您当前所做的不起作用的示例:

>>> "x" in "xxyy"  # works (string is iterable)
>>> "x" in ["x", "y"]  # works (list is iterable)

>>> class MyClass(): pass
>>> c = MyClass()
>>> "y" in c
