从Python中的嵌套列表中检索名称tuple实例的特定字段
我正在开设一个学校项目,这是一个基本的文本冒险游戏,玩家在那里浏览了几个房间,每个房间都有一组物品,并通过花费转弯来将项目添加到其库存中。
由于每个项目都是房间独有的,并且每个项目的统计效益也是唯一的,因此我已经执行以下操作以实现这些:
Item = namedtuple('Item', ['name', 'atk', 'defense', 'agi', 'hp'])
#Sport Store Items
bat = Item('Baseball Bat', 3, 1, 0, 0)
shoes = Item('Running Shoes', 0, 1, 3, 0)
dryeggs = Item('Freeze Dried Eggs', 0, 0, 1, 2)
#Clothes Store Items
belt = Item('Studded Belt', 1, 1, 0, 0)
candy = Item('Japanese Candy', 0, 0, 1, 1)
jacket = Item('Leather Jacket', 0, 3, 0, 1)
#Toy Store Items:
cars = Item('Toy Car Pack', 1, 1, 0, 0)
crayons = Item('Crayons', 0, 0, 1, 0)
toygun = Item('Toy Gun', 2, 1, 0, 0)
#Candle Store Items:
jar = Item('Candle Jar', 2, 0, 0, 0)
matches = Item('Matches', 1, 0, 1, 0)
wax = Item('Wax', 0, 2, 1, 0)
#Music Store Items:
disc = Item('Vinyl Disc', 2, 0, 1, 0)
guitar = Item('Electric Guitar', 3, 0, 0, 0)
symbol = Item('Symbol', 1, 2, 0, 0)
all_items = [
[bat, shoes, dryeggs, '1'],
[belt, candy, jacket, '2'],
[cars, crayons, toygun, '3'],
[jar, matches, wax, '4'],
[disc, guitar, symbol, '5']
]
我的问题在这里,在我的get_items函数中:
def get_items(id):
for i in all_items:
if i[3] == id:
items = i
items = list(items[0:4])
return items
else:
continue
我试图根据基于项目的列表来获得基于项目的列表匹配ID参数。另一个文件中有一个函数,可以将播放器的当前位置接收并将其作为map_id发送到其他函数。我已经成功地做到了这一点,因此商店的名称基于此位置更改,但是我不知道如何处理这些子名单以根据ID返回特定的子列表。
例如,在sport_store代码中,我正在尝试返回结果:
def sport_store():
room_id = '1'
item_select = items.get_items(room_id)
#FIXME: import items.py later with this function in it.
if item_select != []:
if entering == True:
print('You enter the Sporting Goods Store.')
print('There aren\'t many supplies left. What will you pick?')
else:
print('There aren\'t many supplies left. What will you pick?')
print(item_select)
但是,无论我在get_items的循环中更改以使其正常工作,我总是返回原始的item_selection的空列表。我正在尝试从get_items函数中从all_items全局选择匹配的子列表,然后使用该子列表制作一个新列表,该列表已发送到item_selection显示该商店的项目,然后将其格式化为neft natertuples仅显示名称价值。这是可能的还是我需要将数据转换为字典?
I am starting a project for school, a basic text-adventure game, where the player navigates through several rooms, each with a set of items, and adds an item to their inventory by spending a turn.
Since each item is unique to a room and each item is also unique in its stat benefits, I have done the following to implement these:
Item = namedtuple('Item', ['name', 'atk', 'defense', 'agi', 'hp'])
#Sport Store Items
bat = Item('Baseball Bat', 3, 1, 0, 0)
shoes = Item('Running Shoes', 0, 1, 3, 0)
dryeggs = Item('Freeze Dried Eggs', 0, 0, 1, 2)
#Clothes Store Items
belt = Item('Studded Belt', 1, 1, 0, 0)
candy = Item('Japanese Candy', 0, 0, 1, 1)
jacket = Item('Leather Jacket', 0, 3, 0, 1)
#Toy Store Items:
cars = Item('Toy Car Pack', 1, 1, 0, 0)
crayons = Item('Crayons', 0, 0, 1, 0)
toygun = Item('Toy Gun', 2, 1, 0, 0)
#Candle Store Items:
jar = Item('Candle Jar', 2, 0, 0, 0)
matches = Item('Matches', 1, 0, 1, 0)
wax = Item('Wax', 0, 2, 1, 0)
#Music Store Items:
disc = Item('Vinyl Disc', 2, 0, 1, 0)
guitar = Item('Electric Guitar', 3, 0, 0, 0)
symbol = Item('Symbol', 1, 2, 0, 0)
all_items = [
[bat, shoes, dryeggs, '1'],
[belt, candy, jacket, '2'],
[cars, crayons, toygun, '3'],
[jar, matches, wax, '4'],
[disc, guitar, symbol, '5']
]
My issue is here, in my get_items function:
def get_items(id):
for i in all_items:
if i[3] == id:
items = i
items = list(items[0:4])
return items
else:
continue
I'm trying to get the list of items based on the matching ID parameter. There is a function in another file that takes the player's current position and sends it to other functions as the map_id. I've successfully made it so the name of the store changes based on this position, but I cannot figure out how to handle these sub-lists to return a specific sub-list based on the id.
For example, in the sport_store code, I'm trying to return the results like so:
def sport_store():
room_id = '1'
item_select = items.get_items(room_id)
#FIXME: import items.py later with this function in it.
if item_select != []:
if entering == True:
print('You enter the Sporting Goods Store.')
print('There aren\'t many supplies left. What will you pick?')
else:
print('There aren\'t many supplies left. What will you pick?')
print(item_select)
However, no matter what things I change in get_items' loop to get it to work, I always return the original empty list of item_selection. I am trying to select the matching sub-list from the all_items global with the get_items function and then use that sub-list to make a new list that gets sent to item_selection showing the items for that store, and then format the namedtuples in it to show just the names value. Is this possible or do I need to convert the data to a dictionary?

您可以使用所有项目使用字典:
然后,,而不是调用
items.getItems(room_id)
,您可以只做all_items [Room_id]
。希望这有帮助!you can use a dictionary for all items:
then, instead of calling
items.getItems(room_id)
, you could just doall_items[room_id]
. Hope this helps!
