Flask not updating python code dynamically

I am running a web application that return hello world to a web browser using python. The code is as follows:

  1. Code:

     from flask import Flask

 app = Flask(__name__)

 @app.route("/")

 def index():
     return "Hello World!"

  2. after this i am using the command flask run to run the application.py file

  3. Which is working fine on browser. but now if i reset the code again on application.py file to return "Hello world! hello again" and reload the website port the results are not affected in the browser It still returns "Hello World!"

  1. check the log in terminal to see whether it get re-loaded after your update.
  2. if not, activate the debug mode in flask: https://flask.palletsprojects.com/en/1.1.x/quickstart/#debug-mode
export FLASK_DEBUG=1  //Linux or Mac:
set FLASK_DEBUG=1    //windows
  1. also try in Incognito Windows of Browser (which is cache-free)
