How to send data from flask to html template

I have a small application where input is taken from the user and based on it data is displayed back on the html. I have to send data from flask to display on html but unable to find a way to do it. There's no error that I encountered.

[UPDATED]: Python script :

    from flask import Flask, render_template, request
    import random

    app = Flask(__name__, template_folder='templates')

    @app.route('/', methods=['GET','POST'])
    def samplefunction():
        if request.method == 'GET':
            return render_template('new.html')
        if request.mthod == 'POST':
            greetIn = ['hey', 'hi', 'hey there', 'hi there', 'hello', 'hola', 'yoo']
            byeIn = ['bye', 'see you later', 'catch you later', 'toodles']
            nameOut = ['my name is Fatty!!', 'Fatty is my name', 'you can call me Fatty', 'I go by the name of Fatty']
            greetOut = ['hey there!', 'hi!', 'hi there!', 'hey!']
            byeOut = ['bye bye', 'bye. see you later']

            human1 = request.form['human']

            if human1 in greetIn:
                bot = random.choice(greetOut)
                return render_template('new.html', bot=bot)
            else:
                bot = 'Sorry..no idea!!!'
                return render_template('new.html', bot=bot)

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

HTML code :

<html>
  <head>
    <title>BOT</title>
    <script>
        var bot = {{ bot }}
    </script>
  </head>
  <body>
      <h1>Hello, type something to begin!</h1>
      <form method='post'>
        Human: <input type='text' name='human'><br>
        Bot: {{ bot }}<br>
        <input type="submit" name="action">
      </form>
  </body>
</html>

Any help would be appreciated.

Thank You!
