在 Python 2.7 中使用变量引用类属性

Question

我正在开发一款基于文本的游戏，但我还没有为我的战斗系统找到一个非常有效的解决方案。我目前的语句设置如下：

class Weapon1:
    damage = 4
    price = 5

class Weapon2:
    damage = 4
    price = 5

class Enemy1:
    damage = 2
    health = 5

class enemy2:
    damage = 3
    health = 6

def fight():
    Weapon = raw_input("What weapon would you like to use?")
    if Weapon == "Weapon 1":
        if enemy = "Enemy1":
            Enemy1.health -= Weapon1.damage
        else:
            Enemy2.health -= Weapon1.damage
    else:
        if enemy = "Enemy1":
            pass
        else:
            pass

我有比这更多的敌人和类，所以我想有一个可以使用变量引用类的属性的单一语句。我决定不上传实际的函数，因为它超过 100 行。 我所追求的伪代码如下所示：

class pistol:
    damage = 4
    price = 5

class cannon:
    damage = 4
    price = 5

class Enemy1:
    damage = 2
    health = 5

class enemy2:
    damage = 3
    health = 6

def fight():
    Weapon = raw_input("What weapon would you like to use?")
    enemy.health -= weapon.damage

Answer 1

您可以使用简单的dict，这里使用namedtuple 以使代码更易于阅读：

from collections import namedtuple

Weapon = namedtuple('Weapon', ['damage', 'price'])

weapons = {
    'pistol': Weapon(4, 5),
    'cannon': Weapon(4, 5),
    # ...
}

def fight():
    weapon_name = raw_input("What weapon would you like to use?")
    enemy.health -= weapons[weapon_name].damage

Answer 2

在战斗之前制作武器，敌人等级并启动（）

class weapon:
  def __init__(self,d,p):
      self.damage = d
      self.price = p


def initiate():
    pistol = weapon(4,5)
    #....
