In the View Args Through URL Challenge, the first challange asks:

Add a new route to hello() that expects a name argument. The view will need to accept a name argument, too.

Your code is missing this route from part 1. Updating your code:

from flask import Flask

app = Flask(name)

@app.route('/')
@app.route('/<name>')  # <-- new route
def hello(name="Wut"):
    return 'Hello {}'.format('name')

Challenge Task 2

Update the response from hello() to say "Hello {name}", replacing {name} with the passed-in name.

Your code is very close. The error is in the format. You are formatting a fixed string "name" instead of the passed in name. Remove the quote around name in the format():

from flask import Flask

app = Flask(name)

@app.route('/')
@app.route('/<name>')  # <-- new route
def hello(name="Wut"):
    return 'Hello {}'.format(name)  # <-- removed quotes

Why is 'name' quoted in your call of .format()?

from flask import Flask
from flask import request

app = Flask(__name__)

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

This is 100% correct
