python2中的def和return错误

Posted 2021-04-14

嘿，我正在制作一个控制台游戏而且我有一个问题。首先，程序应该如下工作：用户选择攻击力，M级攻击将成功，可能达到（100-M）％。也就是说，更高的幅度意味着错过它的风险更高。例如，如果M为30，则成功的几率为70％，而M为10，成功的概率为90％。如果攻击成功，hp将减少，程序将显示hp的玩家。我写了一些东西：

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值等于零。当我尝试调用hp1或hp2变量时，该值将被删除。

有人可以帮我解决我犯错的地方吗？我必须在30小时内提交我的项目。谢谢。

答案

查看底部的新主要功能，hp值被传入并返回，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 <= 0

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，你的def main（）就像这样：

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)
