If you are just learning about classes, then take a clue from this one…
from random import choice
class Player:
def __init__(self):
self.dead = False
def toggle(self):
self.dead = not self.dead
def shot(self):
return choice([0, 1])
us = Player(), Player()
you, me = us
while True:
if you.dead and me.dead: break
if you.shot(): you.toggle(); print ("You're hit!")
if me.shot(): me.toggle(); print ("I'm hit!")
print ('Bye!')
Run the loop lots of times.
