Suppose there are many condition to check in a game. The conditions which stops the game. So we can do with while loop. But it becomes complex for while loop. so, python uses flag . Flag check if current position is true and many condition are true in game . So, python gives that program is active . Basically flag represent the all condition result.

prompt = "\nplease
          enter the          
          message: "
prompt+="\nplease 
        tell me 
        something
        about you: "

# game is currently 
# active
active = True 
while active:
   a = input(prompt)

   if a == "quit":
      active = False
   else:
      print(a)
