Pygame missing init line 3 and after quit event sys.exit() call

[takonkle]

Using code as is had "pygame.error: video system not initialized" upon window close
Pygame tutorial website says to add (before line 3):
pygame.init()
So that all modules are initialed... May or not be an issue.

in main() after one detects exit event, for loop is left to keep looking for events even though pygame.quit() is called, thus after line with pygame.quit() add:
sys.exit()
and perhaps import sys module in first line.

Summary of changes:

• add "sys, " in front of "pygame" line 1
• insert before line 3 "pygame.init()"
• in main() for loop, after line with "pygame.quit()", add line with "sys.exit()" to not only break for loop and main but exit and not use anything in pygame modules, etc.
