问题描述
我想让角色从字典中将物品添加到其库存中，但是当我添加它们时，它只给我“价值”的回报，而不是“键”的回报。 我想在游戏的不同部分都使用这两种方式，例如“您拿着'钥匙'，它确实'珍视'伤害”。
我想我知道这是在添加字典“值”，因为我的库存类型是“列表”，但是很难找到添加字典项的简单方法。
先谢谢您的帮助！
from random import randint
class Character:
# Instantiates each character with personality traits
def __init__(self, name, health, lives, gender, inventory):
self.name = name
self.health = int(health)
self.lives = int(lives)
self.gender = gender
self.inventory = []
inventoryitems = {
'Breadstick': randint(0,5),
'Magic Axe': randint(50,100),
'Tiny Fists': randint(0,25),
'Sword': randint(15,30)
}
player = Character("Kate", 100, 3, 'female',None)
player.inventory.append(inventoryitems['Magic Axe'])
player.inventory.append(inventoryitems['Breadstick'])
print(player.inventory)

您可以使用函数items()来同时遍历键和值：
from random import randint
class Character:
# Instantiates each character with personality traits
def __init__(self, name, health, lives, gender, inventory):
self.name = name
self.health = int(health)
self.lives = int(lives)
self.gender = gender
self.inventory = []
inventoryitems = {
'Breadstick': randint(0,5),
'Magic Axe': randint(50,100),
'Tiny Fists': randint(0,25),
'Sword': randint(15,30)
}
player = Character("Kate", 100, 3, 'female',None)
# item will be a (key, value) pair
for item in inventoryitems.items():
player.inventory.append(item)
# or if you only want to add specific items
items_to_add = ['Breadstick', 'Magic Axe']
for item in items_to_add:
player.inventory.append((item, inventoryitems[item]))
print(player.inventory)
将打印例如
[('Breadstick', 5), ('Magic Axe', 51), ('Tiny Fists', 21), ('Sword', 17), ('Breadstick', 5), ('Magic Axe', 51)]
请注意，两次添加项目不会将新的随机值应用于每个随机值，这可能不是您想要的。

在您的班级中使用字典很简单，然后您可以使用player.inventory.keys（）按名称生成项目列表，稍后还可以通过player.inventory ['object_name']以非常简单快速的方式访问项目
from random import randint
class Character:
# Instantiates each character with personality traits
def __init__(self, name, health, lives, gender, inventory):
self.name = name
self.health = int(health)
self.lives = int(lives)
self.gender = gender
self.inventory = {}
inventoryitems = {
'Breadstick': randint(0,5),
'Magic Axe': randint(50,100),
'Tiny Fists': randint(0,25),
'Sword': randint(15,30)
}
player = Character("Kate", 100, 3, 'female',None)
player.inventory['Magic Axe'] = inventoryitems['Magic Axe']
player.inventory['Breadstick'] = inventoryitems['Breadstick']
print(player.inventory)
