how do I run a python flask app code example
Example 1: simple flask 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()
Example 2: run flask app from command line
# For bash do this:
set FLASK_APP=<app_name>
# For powershell do this:
$env FLASK_APP=<app_name>
# Run it like this
flask run
