How to run Python script on terminal?
This Depends on what version of python is installed on you system. See below.
If You have Python 2.* version you have to run this command
python gameover.py
But if you have Python 3.* version you have to run this command
python3 gameover.py
Because for MAC with Python version 3.* you will get command not found error
if you run "python gameover.py"
