Q:

flask how to run app

# Extremely simple flask application, will display 'Hello World!' on the screen when you run it
# Access it by running it, then going to whatever port its running on (It'll say which port it's running on).
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

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

$ export FLASK_APP=hello.py
$ python -m flask run
 * Running on http://127.0.0.1:5000/

# For bash do this:
set FLASK_APP=<app_name>

# For powershell do this:
$env FLASK_APP=<app_name>

# Run it like this
flask run

from flask import Flask
app = Flask(__name__)

@app.route('/')
def index():
    return 'Flask'

# I am assuming that you have configured the app name as "app"

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