TypeError: 'str' object is not callable when creating reddit bot

Question

I am trying to build a reddit bot that comments when one of the phrases is commented, but It doesn't work

import praw
import time

reddit = praw.Reddit(
    client_id='---',
    client_secret='---',
    user_agent='---',
    username='---',
    password='---')

subreddit = reddit.subreddit("okbuddyreiner")

quote = "I want to kill myself"

for submission in subreddit.hot(limit=10):
    print("**********")
    print(submission.title)

    for comment in submission.comments:
        if hasattr(comment, "body"):
            comment_lower = comment.body.lower()
            if " lainah " in comment_lower:
                print("--------")
                print(comment.body)
                comment.body(quote)
                time.sleep(660)
            if " reiner " in comment_lower:
                print("--------")
                print(comment.body)
                comment.body(quote)
                time.sleep(660)

after that I get this error, and I cannot fix it, I have tried everything

Traceback (most recent call last):
  File "/home/Lainahbot/reddit_bot.py", line 26, in <module>
    comment.body(quote)
