I keep getting a "Bummer: You should have a dunder main statement at the end of your file." message. I passed step 2, which was to add the dunder main statement. But now when I add the route and index function, it tells me this. I don't think I have anything wrong here. Can anybody spot a mistake?
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 there, Mat Clark! The only thing I can see that isn't quite right has to do with PEP 8 standards that say that there should be two blank lines after a function definition. So if I add an extra blank line between the
return 'Hello Flask' and the "dunder main", the challenge passes.
I'll reach out to the education team to see if this was intended.
Hope this helps!
