python2中的def和返回错误

Question

嘿，我正在开发一个控制台游戏，但我遇到了一个问题。首先，程序应该如下工作： 用户选择攻击力， 规模为 M 的攻击将以 (100-M)% 的几率成功。也就是说，更高的幅度意味着更高的错过它的风险。比如M是30，成功的几率是70%，而M是10，成功的几率是90% ：

import random


def attack1():
    hp2=100
    chance_of_damaging=random.randint(0,100)
    print "your chance of damaging", chance_of_damaging
    while True:
        attack_magnitute=input("Choose your attack magnitude between 1 and 50: ")

        if attack_magnitute > 50:
            print "The attack magnitude must be between 1 and 50."

        elif attack_magnitute < 1:
            print "The attack magnitude must be between 1 and 50."
        else:
            break


    while True:
        if chance_of_damaging > attack_magnitute:
            print "attack is succesful"
            hp2=hp2-attack_magnitute
            return hp2
        else:
            print "attack is unsuccesful"
            return hp2
print  attack1()


def attack2():
    hp1=100
    chance_of_damaging=random.randint(0,100)
    print "your chance of damaging", chance_of_damaging
    while True:
        attack_magnitute=input("Choose your attack magnitude between 1 and 50: ")

        if attack_magnitute > 50:
            print "The attack magnitude must be between 1 and 50."

        elif attack_magnitute < 1:
            print "The attack magnitude must be between 1 and 50."
        else:
            break


    while True:
        if chance_of_damaging > attack_magnitute:
            print "attack is succesful"
            hp1=hp1-attack_magnitute
            return hp1
        else:
            print "attack is unsuccesful"
            return hp1
print attack2()

程序应继续运行，直到其中一个 hp 值等于 0 当我尝试调用 hp1 或 hp2 变量时，该值被删除。

有人可以帮我解决我的错误吗？我必须在 30 小时内提交我的项目。提前致谢。

看底部新的main函数，hp值是传入并返回的，而不是在攻击函数开始时重新初始化。循环继续，直到其中一个 hps

import random


def attack1(current_hp):
    hp2=current_hp
    chance_of_damaging=random.randint(0,100)
    print "your chance of damaging", chance_of_damaging
    while True:
        attack_magnitute=input("Choose your attack magnitude between 1 and 50: ")

        if attack_magnitute > 50:
            print "The attack magnitude must be between 1 and 50."

        elif attack_magnitute < 1:
            print "The attack magnitude must be between 1 and 50."
        else:
            break


    while True:
        if chance_of_damaging > attack_magnitute:
            print "attack is succesful"
            hp2=hp2-attack_magnitute
            return hp2
        else:
            print "attack is unsuccesful"
            return hp2



def attack2(current_hp):
    hp1=current_hp
    chance_of_damaging=random.randint(0,100)
    print "your chance of damaging", chance_of_damaging
    while True:
        attack_magnitute=input("Choose your attack magnitude between 1 and 50: ")

        if attack_magnitute > 50:
            print "The attack magnitude must be between 1 and 50."

        elif attack_magnitute < 1:
            print "The attack magnitude must be between 1 and 50."
        else:
            break


    while True:
        if chance_of_damaging > attack_magnitute:
            print "attack is succesful"
            hp1=hp1-attack_magnitute
            return hp1
        else:
            print "attack is unsuccesful"
            return hp1
def main():
     hp1, hp2 = (100,100)
     while hp1 > 0 and hp2 > 0:
        hp1 = attack1(hp1)
        hp2 = attack2(hp2)
main()

编辑： 如果你想打印出 hp1 和 hp2 的最终状态，让你的 def main() 像这样：

def main():
     hp1, hp2 = (100,100)
     while hp1 > 0 and hp2 > 0:
          hp1 = attack1(hp1)
          hp2 = attack2(hp2)
     print "Final State of hp1: " + str(hp1)
     print "Final State of hp2: " + str(hp2)
