Why isn't this code working?

It doesn't work when I give the argument name a default value either. What am I doing wrong?

flask_app.py
from flask import Flask
from flask import request

app = Flask(__name__)

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

The issue is you are not grabbing the name from the request query arguments.

name = request.args.get('name')

Hi Mesrop

The problem is you have not defined what name is. You need to pass a default value for the variable name.

See below

from flask import Flask
from flask import request

app = Flask(__name__)

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