Here's my code :
from flask import Flask from flask import request
app = Flask(name)
@app.route('/') def index(name="Treehouse"): name = request.args.get('name', name) return 'Hello {name}'.format(name)

15,391 PointsIN YOUR CODE :
app = Flask(name)
its (dunder name) i.e double_underscores name double_underscores. It should be
app = Flask(__name__)
NEXT, when you are doing format on your string, the placeholder need not have the variable name, which means it should be {} rather than {name}, as you are already passing it in .format(name).
{} is just a placeholder to tell where the string should be placed.
return 'Hello {name}'.format(name)#IS WRONG
return 'Hello {}'.format(name)# IS RIGHT
Your code should look something like this:
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
def index(name="Treehouse"):
name = request.args.get('name', name)
return 'Hello {}'.format(name)
This should work fine. Hope I cleared you question. Cheers!
