Flask with SQLAlchemy Basics Challenge Task 3 of 3

I have been following the tutorial, but keep getting the same error with the code I've written. Is there a syntax or formatting error somewhere that I am missing?

# insert your code here
from flask import Flask

app = Flask(__name__)

def index():
    return 'Hello Flask'

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

Hey Zack Guignardi, your code is basically correct. The challenge checker can be very picky regarding PEP8 guidelines.

In your case, the checker is looking for two blank lines above the dunder main if statement.

Post back if you need more help. Good luck!!!
