Guess the random number from 0 to 9 in this web game made with Python and Flask Framework

• Random
  
• Flask
  

In case you don't have Flask module installed just type the code below in a terminal:

pip install Flask

After downloading and installing Flask, you must setup the FLASK_APP environment variable:

To run the application, use the flask command or python -m flask. Before you can do that you need to tell your terminal the application to work with by exporting the FLASK_APP environment variable:

export FLASK_APP=server.py
flask run

set FLASK_APP=server.py
flask run

$env:FLASK_APP = "server.py"
flask run

If anything is not running properly, I surely recommend you to search at the Flask Official Documentation:
