Praw reddit fetch N comments (python)

I want to fetch certain number of comment. How can i do this? My code:

subreddit = reddit.subreddit("askReddit")

top = subreddit.hot(limit=1)

for submission in top:

    print("Title : ", submission.title)

    for comment in submission.comments:

        # avoid error. Doesn't important
        if isinstance(comment, MoreComments):
            continue

        print("Comment :", comment.body)

That takes too long fetch comments
