web services in python invoking the service we will use web browser to access the web service to do this we must enter the full url that will route the request to our running application and to the welcome(function the url is actually comprised of two elementsthe first part is the machine on which the application is running and the port that it is using to listen for requests this is actually listed in the above output--look at the line starting 'running onthis means that the url must start with indicates that the application is running on the computer with the ip address and listening on port we could of course also use localhost instead of the remainder of the url must then provide the information that will allow flask to route from the computer and port to the functions we want to run thus the full url is the web browser shown belowas you can see the result returned is the text we supplied to the jsonify(function but now in plain json format and displayed within the web browser you should also be able to see in the console output that request was received by the flask framework for the get request mapped to the /hello url [ /may/ : : "get /hello http/ one useful feature of this approach is that if you make change to your program then the flask framework will notice this change when running in development mode and can restart the web service with the code changes deployed if you do this you will see that the output notifies you of the changedetected change in 'hello_flask_world py'reloading restarting with stat this allows changes to be made on the fly and their effect can be immediately seen
