[Tutor] A way to restart a script after it runs?

[Lloyd Hugh Allen]

There's also a fairly common convention,

done = False
while not done:
    {do stuff}

then if you want to set an exit condition (perhaps the user selects
"quit" from a menu), the loop will stop repeating if you ever set done
= True.
