Creates a bot that listens to comments in a list of subreddits and calls a given function on each new comment.

  • redditpraw.Reddit instance. Check Bot Account Setup on how to create it.
  • name – Bot name
  • func_comment – Comment function. It needs to accept a praw.models.Comment object and may take more arguments. For each comment created in subreddits, a praw.models.Comment object and all fun_comments_args are passed to func_comment as arguments.
  • func_comment_args – Comment function arguments.
  • subreddits – List of subreddit names. Example: ['AskReddit', 'Videos', ...]
  • n_jobs – Number of parallel threads that are started when calling start() to process in the incoming comments.

Example usage:

# Write a parsing method
def parse(comment):
   if 'banana' in comment.body:
       comment.reply('This comment is bananas.')

reddit = praw.Reddit(...) # Create a PRAW Reddit instance
bot = CommentBot(reddit=reddit, func_comment=parse)

It will listen to all new comments created in the subreddits list.
