Python Flask Basics Welcome to Flask First Steps

I can't see my code in the browser: workspace unavailable?

I tried to run my first Flask code in the browser but this message appeared:

Workspace Unavailable This is a preview link for a Treehouse Workspace that is not currently active. If you are the workspace owner, you can launch it again via the Treehouse site.

What is happening? This is my code:

from flask import Flask

app = Flask(__name__)

def index():
    return "Hello Treehouse"

app.run(debug=True, port=8000, host:'')

Sometimes helps to try a different port such as 8080 instead of 8000.

What command was used in the console window to launch the flask server app? Can you post the console output?

I solved the problem, it was for not writing the name of the file on the terminal.

I have this same problem. How did you fix it?

Joseph Martin Nograles, in console, type python + the name of your project.py.

My command is:

python simple_app.py

This sends the new information and the new code to the door.
