Flask SQLAlchemy -- "you should have __main__ at the end of your code"?

Extra set of eyes? I see nothing wrong here. In fact, the error is referring to the last part of the challenge, which passed.

thanks!

app.py 
# insert your code here
from flask import Flask


app = Flask(__name__)

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

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

Hi! I think what's catching you is a PEP8 guideline. There should be two empty spaces before and after a function so you just need one more empty space after your index function.

# insert your code here
from flask import Flask


app = Flask(__name__)


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


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

yeah ok I read through the pep8 guidelines again to make sure I was not missing anything and I guess I missed: "Surround top-level function and class definitions with two blank lines."
