How do i insert chat bot to a website in python?

thanks for clicking in. I am building a website with Flask, and I want to insert a chat bot in it. You can see there is nothing yet. This is app.py

from flask import Flask
from flask import url_for, redirect, render_template

app = Flask(__name__)

@app.route('/')
def home_get():
    return render_template('show.html')

app.secret_key = '45653537'

if __name__ == "__main__":
    app.run()

The bot does not aim to be AI. It is very dumb and simple. How can i build the chat environment like that in Cleverbot? This is bot.py

import random

GREETING_KEYWORDS = ["hello", "hi", "greetings", "sup", "what's up"]
GREETING_RESPONSES = ["'sup bro", "hey", "*nods*", "hey you get my snap?"]

while True:
    sentence = raw_input().lower()

    if set(GREETING_KEYWORDS).intersection(sentence.split()):
        print(random.choice(GREETING_RESPONSES))

    else:
        print("what?")

Thank you very much!
