need to render python in html using flask

this is the 1st time I am rendering HTML using python and flask so my concepts are very new..

I tried the A Simple Example in Project and my issue is if I change return "Hello, World!" in the hello() python function to say return "ABC XYZ" and do a refresh of the browser url(http://127.0.0.1:5000/), the new value (ABC XYZ) doesnt get rendered immediately; so how do I make it to render upon a browser refresh?

>Solution :

The problem here is that the Flask application does not auto-reload even if you make any changes in code files.

But if you want Flask to auto-reload whenever you save(or change) any file then you have to set debug to True

If you are using app.run() then do this

app.run(debug=True)

or if you running it using a command line like flask run. Then add --debug in the command.

example

flask –app Project run –debug
