Web development using Flask and Python

[kirito85]

Hi, I am doing web development using Flask and Python. However when i try to integrate the backend to the Flask, I am stuck at this def index(): return Google. It comes up in the backend coding program but I would like it to appear frontend on a website somehow. Appreciate any kind advice thanks.

@app.route('/')
@app.route('/index')
def index():
    return Google
