Python Flask Basics Welcome to Flask Request args

Flask challenge:Didn't get the expected response.

What's wrong in my code? (Challenge is:Import request from Flask. Then update the index view to return "Hello {name}", replacing {name} with a name argument in the query string.)

flask_app.py 
from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/')
def index(name="Larri"):
    name = request.args.get('name', name)
    return "Hello{}".format(name)

Hi, larri krown Sooooo closed, only the return String format is off by couple of spaces.

return "Hello {} ".format(name)

What's the point of putting both 'name' and name in request.args.get()? I understand the purpose of the second name but the first one in quotation marks, what's the deal with that one?

as i see this, one 'name' is the variable from flask/jinja template , second name is the value this variable, but i'm not shure

Yeah, I'm not sure either. But, I believe this isn't the usual convention with Flask as introduced in the next video with variables directly in the URL.

I little confused you, it's exactly variables from the URL

To access parameters submitted in the URL (?key=value) you can use the args attribute:

searchword = request.args.get('key', '')

First 'name' is key from URL which return value, Second name get default value from function param named as name That's how i see it
