Can't seem to figure this one out. Bummer! didn't get the expected result

Not sure what I'm doing wrong, or what it's really even specifically asking me to do.

flask_app.py 
from flask import Flask
from flask import request
app = Flask(__name__)

@app.route('/')
@app.route('/<name>')
def index(name="brian"):
     return 'Hello {}'.format(app)

So then I tried this too and it doesn't work

from flask import Flask from flask import request app = Flask(name)

@app.route('/') @app.route('/<name>') def index(name="brian"): return 'Hello {}'.format(name)

So then I tried this, and it seems like I'm getting closer?

from flask import Flask from flask import request app = Flask(name)

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

def index(name): return 'Hello {}'.format(name)

Then I tried this and I got an error that says : "Bummer! '/' gave a non-200 response. Did you change the route?" No, I didn't change the route. Am I supposed to? To where?

from flask import Flask from flask import request app = Flask(name)

@app.route('/') def index(): return 'Hello {}'.format(input())

This is my last crack at it before I just take a break for a bit lol. Still can't get it. Not sure what it wants me to put in the app route. Am I missing something obvious?

from flask import Flask from flask import request app = Flask(name)

@app.route('/?index') def index(name="Brian"): name = request.args.get('name', name) return "Hello from {}".format(name)

Finally figured it out.

from flask import Flask from flask import request app = Flask(name)

@app.route('/') def index(): name = request.args.get('name') return 'Hello {}'.format(name)
