What's wrong with my view (app.route) . I don't understand why it isn't running the third task properly. Thanks!

Please help

app.py 
from flask import Flask
app = Flask(__name__)

@app.route('/')
def index():
    return "Hello Flask"

if __name__ == '__main__':
    app.run(debug=True, host='0.0.0.0', port=8000)

Hi Luis!

The tester for that challenge is just too particular (kind of a 'biatch, in my book LOL)!?!

I had to do boatload of trial-n- error to get it right!

The "Bummer" hints are not very helpful in this challenge.

Sometimes I have NO IDEA what the challenge is asking for until I get it right or look up the answer somewhere else (or consult the forums, like you did).

Syntax is generally so arbitrary that I can't understand much of it without seeing several correct/exact examples.

Without many great/accurate examples, many tutorials are useless. A lot leave out critical details without which you can't code it correctly. For example, I took the OWASP course, which was good. but it's missing a lot of critical details about how to implement it - they show a lot of code samples, but not where it goes. (On the client? On the server? In which file? Do I have to do it? Or do I have to involve my hosting provider's tech support, etc.?!? It can get very frustrating.) Unfortunately, I usually have to consult copious 3rd-part resources to fully grasp much of the material.

This passes all three:

from flask import Flask

app = Flask(__name__)


@app.route('/')
def index():
    return "Hello Flask"


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)

The double spacing between lines helped as did not putting dunder name in quotes!?!

Like this (you had it right):

__name__ instead of '__name__'

I also got rid of "debug=True" in the app.run statement.

I hope that helps.

Stay safe and happy coding!
