What am i suppose to do here?

Import request from Flask. Then update the index view to return "Hello {name}", replacing {name} with a name argument in the query string.

flask_app.py 
from flask import Flask

app = Flask(__name__)

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

Kenneth:

The first thing you need to do is import request "from flask import request". The second step is you have to get a name from the query string:

@app.route("/<name>")

To capture this you will need to add the name parameter to the function, such as:

def index(name):

Then you can reference name in the function like normal.

return "Hello {}".format(name)
