如何使用类中的方法正确地遍历代码的一部分？

Question

我正在学习Python中的类，并尝试制作一个简单的战斗游戏。这段代码运行得很好，只要我多次打印devin.battle()，但我想要一个while循环，这样它就会恢复到询问用户是否愿意发动战斗，同时从命中点中推断出攻击。

start_battle = input("Would you like to start a battle? Y/N ===>  ")

class People:
        max_hit_points = 150
        current_hit_points = 150
        current_strength = 5
        defence = 0

        def __init__(self, name, current_hit_points):
            self.name = name
            self.current_hit_points
            self.damage = 50
            

        def battle(self):
            if start_battle == "Y":
                self.attacked()
            elif start_battle == "N":
                print("okay, nevermind then")
            
        def attacked(self):
            self.current_hit_points -= self.damage
            print("You have been attacked")
            if self.current_hit_points > 0:
                print("Try again newb!")
            else:
                print("Your HP has reached 0, you are dead")

        def __str__(self):
            return f"{self. name} has {self.current_hit_points}HP remaining"
        


devin = People("Devin", 150)
devin.battle()
print(devin)

但是，当我在整个代码中添加一个时，Python就冻结了。

start_battle = input("Would you like to start a battle? Y/N ===>  ")

class People:
        max_hit_points = 150
        current_hit_points = 150
        current_strength = 5
        defence = 0

        def __init__(self, name, current_hit_points):
            self.name = name
            self.current_hit_points
            self.damage = 50

        while current_hit_points > 0:
            def battle(self):
                if start_battle == "Y":
                    self.attacked()
                elif start_battle == "N":
                    print("okay, nevermind then")
                
            def attacked(self):
                self.current_hit_points -= self.damage
                print("You have been attacked")
                if self.current_hit_points > 0:
                    print("Try again newb!")
                else:
                    print("Your HP has reached 0, you are dead")

            def __str__(self):
                return f"{self. name} has {self.current_hit_points}HP remaining"
            continue
        
        else:
            print("You are dead") 

devin = People("Devin", 150)
devin.battle()
print(devin)

如果有人能向我解释为什么会结冰，以及我如何正确地循环一场战斗，我将不胜感激。

您在这里有多个问题，并且不是很清楚您要做什么，但根据您的评论，这里有一些指导，请确保阅读# code comments

class People:
        max_hit_points = 150
        current_hit_points = 150
        current_strength = 5
        defence = 0

        def __init__(self, name, current_hit_points):
            self.name = name
            # you forgot to actually assign the hit points
            self.current_hit_points = current_hit_points
            self.damage = 50

        def battle(self):
            while self.current_hit_points > 0:
                # you want to ask the user every round?
                start_battle = input("Would you like to start a battle? Y/N ===>  ")
                if start_battle == "Y":
                    self.attacked()
                    # note that the user didnt get to attack back
                    # maybe print(self) here so the user can see his hp?
                elif start_battle == "N":
                    print("okay, nevermind then")
                    break
            else:
                print("You are dead") 
                
        def attacked(self):
            self.current_hit_points -= self.damage
            print("You have been attacked")
            if self.current_hit_points > 0:
                print("Try again newb!")
            else:
                print("Your HP has reached 0, you are dead")

        def __str__(self):
            return f"{self. name} has {self.current_hit_points}HP remaining"

devin = People("Devin", 150)
devin.battle()
print(devin)
