Creating a new Flask application

To begin with, we'll create the skeleton of our new Flask application, which is pretty much the same as our Hello World application. Open headlines.py in your editor and write the following code:

from flask import Flask

app = Flask(__name__)

@app.route("/")
def get_news():
  return "no news is good news"

if __name__ == '__main__':
  app.run(port=5000, debug=True)

This works exactly as before. You can run it in your terminal with python headlines.py. Open a browser and navigate to localhost:5000 to see the no news is good news string displayed. However, although the old adage may be true, it's bad news that our app does not do anything more useful than this. Let's make it display actual news to our users.
