Pygame code will not actually start game?

Question

We have been doing Pygame at school and its our first time ever using the language. This piece of code does not start the game properly and plays the game over sound. Any tips for fixing this so it actually works. I got this piece of code from an online book called invent with python(https://inventwithpython.com/invent4thed/chapter21.html) and should be creating a game that allows for characters to move around the screen and interact with enemies but instead after pressing any key it will instead play the game over clip.

import pygame, random, sys

WINDOWHEIGHT = 600
TEXTCOLOR = (0,0,0)
BACKGROUNDCOLOR = (255, 255, 255)

BADDIEMINSPEED = 1
BADDIEMAXSPEED = 8
