[Tutor] sys.exit help

[Jason MacFiggen]

I was wondering how can I change sys.exit so if you use command line to run
the program. it prompts a message asking if the user wants to exit instead
of automatically just exiting?

import random
import sys
my_hp = 50
    mo_hp = 50
    menu1 = """
        Menu Selections:
        1 - Attack
        2 - Defend
        3 - Help
        4 - Exit
        """
    print menu1
    while True:
        my_dmg = random.randrange(1, 20)
        mo_dmg = random.randrange(1, 20)

        choice = input ("\nEnter your selection. ")
        choice = float(choice)
        print
        if choice == 1:
            mo_hp = mo_hp - my_dmg
            if mo_hp <= 0:
                print "Iris is at 0 Hit Points!\nYOU HAVE SLAIN IRIS!"
                sys.exit(0)
            elif mo_hp > 0:
                print

                sys.exit(0)
