python local host http://127.0.0.1:5000/ not refreshing to new request from flask

Question

At the first time when I'm running the below code in Python, it's succesfully running in localhost by displaying hello, I'm using the atom editor.

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_wrld():
   return "hello"

if __name__ == '__main__':
   app.run()

But when I'm changing my return to hello python as follows:

from flask import Flask
app = Flask(__name__)

@app.route('/')
def dhineTrend():
   return "hello python"

if __name__ == '__main__':
   app.run()

It's running in localhost but when I'm hitting the browser it keep on showing old hello. How to overcome it?

Note: After first run I cut the run, then only request the second.

Enable DEBUG to auto reload files on change,

app = Flask(__name__)
app.debug = True

There are multiple ways to do this,

app.config.update(DEBUG=True)

Or

app.config['DEBUG'] = True

Or, Create a config.py defining all the Flask settings

app.config.from_object('config')
