def startPygame():
  pygame.display.set_caption(option + " Tracking System")
  pygame.mouse.set_visible(True)
  screen.fill((255, 255, 255))
  targetRectangle = pygame.draw.rect(screen, (255, 0, 0), (176, 134, 7, 7))
  pygame.display.flip()
  #define function to update pygame window 
def updateWindow():
  screen.fill((255, 255, 255))
  global targetRectangle
  global xPosition
  global yPosition
  targetRectangle …
