Python Flask Basics Welcome to Flask View Args Through URL

Flask: Replace name with passed in name. What am I doing wrong?

I thought I am defining name in the passed in parameters. This worked in my workspace.

What am I doing incorrectly?

Also, is anyone having trouble with workspaces? I can't view my code anymore.

Cheers,

Jon

flask_app.py 
from flask import Flask

app = Flask(__name__)

@app.route('/<name>')
def hello(name="Jon"):

     return "Hello {}".format('name')

Don't provide a default argument for the passed in name. Also, you should have two different routes, one for the original, "/" and one for the new "/<name>"

This is frustrating John. I had both app routes when I first started this, and it told me "exercise 1 is no longer working!"

I just opened a new browser window and started over and it worked.

Should I be clearing my cookies or something? Use another browser? Every exercise I am having problems like this.

By the way, thank you very much for your detailed explanations, much appreciated.

No problem, I'm glad you at least got it to work. I never had that problem with code challenges though -- that seems a bit odd. If it happens again, post your code and the steps you took so I can get a better idea of what is going on.

The variable name, and the string 'name', are not the same thing. Your .format() is using the string, so whatever name gets passed in through the URL isn't going to be in the response.
