When my conditional is false in when it turns true why wont the loop stop

Question

Here is my code in python 3.4 it just keeps running the loop until the system exit when the player dies this is part of an rpg game i have been making for fun

Not entire code please note if you would like to see entire code please ask only combat function shown

def combat(h, a, d, x):
    global attack
    global health
    global defence
    global xp
    death = False
    while death == False:
        eab = random.randint(1, 10)
        yab = random.randint(1, 10)
        cattack = 0
        cdefence = 0
        cattack = attack
        cdefence = defence
        cattack = cattack + yab
        a = a + eab
        d = d - cattack
        print("you strike for " + str(cattack) + " damage")
        cattack = cattack - d
        if cattack > 0:
            h = h - cattack
        if d > 0:
            print("the enemy has " + str(d) + "defence left")
        if h > 0:
            print("the enemy has " + str(h) + "Health left")
        else :
            print("the enemy dies")
            death == True
            xp = xp + x
        print("they strike back for " + str(a))
        cdefence = cdefence - a
        a = a - cdefence
        if a > 0:
            health = health - a
        if cdefence > 0:
            print("you have " + str(cdefence) + " defence left!")
        if health > 0:
            print("you have " + str(health) + " health left")
        else :
            sys.exit("YOU DIED A HORRIBLE DEATH")

Answer 1

Your problem is with this line: death == True

This compares the variable 'death' with the True function, which will never work. What you need to do instead is replace that with death = True.

This should fix your code.
