How to check if website post title has certain word in it?

I'm building one bot for fun and I need some help. I successfully made the part where my bot will automatically reply to comments if there is already a comment containing certain words in it. (I removed all bot info from the beginning including my account info)

import praw
import time

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

subreddit = reddit.subreddit("all")


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

    for comment in submission.comments:
        if hasattr(comment, "body"):
            comment_lower = comment.body.lower()
            if "certain word" in comment_lower:
                print("-------")
                print(submission.title)
                print(comment.body)
                print(comment.author)

                comment.reply("Test reply")
                time.sleep(780)

This code, once executed gives such output which is alright(I randomly put r/love so I can show you its output), in this case, it outputs post title, a comment which includes word "love" in it and author of that comment.

Now I can't figure out how to make bot to do the same thing(prints post title,comment and its author) but if there is certain word in the POST TITLE and not the comments section.

EDIT : This is what I tried

for title_name in submission.title:
    if hasattr(title_name, "title"):
        title_lower = title_name.body.lower()
        if " love " in title_lower:
            print(submission.title)
