When running flask app, like

... 
if __name__ is "__main__":
    app.run(port=self.port)

...

There are some messages for running.

* Serving Flask app "__main__" (lazy loading)
* Environment: production
  WARNING: Do not use the development server in a production environment.
  Use a production WSGI server instead.
* Debug mode: off
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

How I disable all these messages?

To disable Flask from displaying warning banner messsage about using a development server in a production environment, add the 2 cli lines before running flask:

from flask import Flask
import sys

cli = sys.modules['flask.cli']
cli.show_server_banner = lambda *x: None

app = Flask(__name__)
app.run(host='0.0.0.0', port='80')
