Unable to run a Flask app on Waitress WSGI

I want to run a flask app on waitress and it’s not working.
My code:

from flask import Flask

app = Flask(__name__)

if __name__ == "__main__":
    from waitress import serve
    serve(app)

When I try to run the app from cmd it gets stuck and doesn’t do anything.

Thanks

>Solution :

Why do you think it’s stuck? By default waitress has log level set to WARNING, so you don’t see any debug outputs.
Try changing logging configuration, like this:

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(message)s')
