I get an 200 (routing?) error when I enter this code for Flask Challenge 1. I don't see the problem..
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
def index(name):
return "Hello {}".format(name)
[MOD: added ```python formatting -cf]

Task 1 of 1: Import 'request' from 'Flask'. Then update the index view to return "Hello {name}", replacing {name} with a name argument in the query string.
from flask import Flask
# Import 'request' from 'Flask'....
from flask import request
app = Flask(__name__)
@app.route("/")
def index(name="Treehouse"):
# with a name argument in the query string.
name = request.args.get('name', name)
# update the index view to return "Hello {name}"
return "Hello {}".format(name)

from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
@app.route('/<name>')
def index(name='Student'):
return "Hello {}".format(name)

3,421 PointsThanks. I tried your code (this is for challenge task 1 of 1 in flask basics), and it is telling me it didn't get the expected response.
Here is my code: It should be identical to yours.
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
@app.route('/<name>')
def index(name='Student'):
return "Hello {}".format(name)

3,421 PointsI tried this and it didn't work, do you know why it's telling me it didn't get the expected response?
