python - 我试图为健康栏做一个 while 循环，但出现除法错误

Question

你好，所以我有一小段代码来自我的大代码，用于显示游戏中敌人的健康栏，但出于某种原因，即使我认为它应该停止循环，循环仍在继续，有什么我吗失踪或做错了吗？

import pygame, sys
import time
import random
import os
import sqlite3
import os.path

damage_done = 1
random_monster_health = random.randint(7,10)
alive = True
print (random_monster_health)

while alive == True:
    mob_health = random_monster_health - damage_done
    print ("mob health is {}" .format(mob_health))
    if mob_health != 0:
        percent_damage_done = mob_health / int(random_monster_health)
        how_much_health_bar = 1180 * (percent_damage_done)
    else:
        pass
    random_monster_health = mob_health
    print(random_monster_health)
    if mob_health != 0:
        print("the monster is still alive")
        pass
    else:
        alive == False
        print ("the monster is dead")
        pass

print("the loop has ended")

Answer 1

else:
    alive == False
    print ("the monster is dead")
    pass

这部分是错误的。您正在比较 alive与 False它应该是

else:
    alive = False
    print ("the monster is dead")

旁注:您不需要在每个 if 语句中都使用 pass。
