It depends on which version of python is installed on your system. See below.
If you have Python version 2. *, you should run this command
python gameover.py
But if you have Python version 3. *, you should run this command
python3 gameover.py
Because for a MAC with Python version 3. * you get a command not found error
if you run "python gameover.py"
