If the sprite is showing, it will hide the sprite. If the sprite is already hidden, nothing happens.
The example demonstrates the show and hides of the sprite in Python.
Code
sprite = Sprite('Tobi')
import time
sprite.gotoxy(0, 0)
sprite.setsize(200)
while True:
sprite.show()
time.sleep(1)
sprite.hide()
time.sleep(1)
