RPG库存无法正常工作。对不起，如果我的代码太糟糕了，我才开始学习Python。
Python 3.7.0
空闲3.6。 （64位）

#firstly I created classes for items and items_in_body_parts.
#for example, one of them:
class item_for_put_on:
def __init__(self):
self.name = ''
self.body_part = '' #for what body part? like in Diablo, for example, you can take a weapon in your hand and put on a helmet on your head
#there is a lot of other staff, i deleted it to make it simple, here are the main things:
right_hand_item_1 = right_hand_item()
on_head_item_1 = on_head_item()
item_for_put_on_1 = item_for_put_on()
item_check_on = item_check_on_class()
right_hand_item_1.name = ''

#here was some code - to describe to player all content of the bag - it works good

#SO HERE WE CAN SEE WRONG INFO --- if you put on only one thing, everything is right, but if you put on the second thing - there will be two sticks (one on head, one in hand) or two helmets (one on head, one in hand)
在这里我们可以看到错误的信息：如果只穿一件东西，那一切都是对的，但是如果穿第二件东西-将会有两根棍棒（一个在头上，一个在手）或两个头盔（头一个，手一个）；由于项目名称存在问题。而且，如果我为其添加更多的物品和插槽，最后一个将是例如Shield-英雄的身体上将会有很多盾牌，而不是正确的物品。当然，库存中没有以前的物品。
在我看来，问题出在全局变量的某个地方，或者while循环在某个地方无法正常工作（也许永远分配一秒钟，我不知道）。
似乎当我们更改item_for_put_on_1时，它会更改所有已分配的内容-函数item_put_on（）中的on_head_item_1和right_hand_item_1。
如果我在装备好物品后在item_put_on（）中使用item_for_put_on_1的清除功能（使其成为=''），它将以某种方式从设备中删除物品的名称
因此，主要问题与item_for_put_on_1有关，但我需要帮助以找到解决问题的方法。
答案 0 :(得分：0)
我解决了这个问题，删除了object和object.names。现在，我使用简单的变量-使它们遍及全球。
现在可以了！但是，即使我们用字典“ all_item_names [i] [0]”中的直接名称替换了愚蠢的不必要的“ item_for_put_on_1”，我也不明白是什么问题。用这种方法不能解决问题。下面的代码仍然无法正常工作（更改名称也存在同样的问题）
# item_left_hand, item_on_head - these are objects, they got .name firstly
# below code is in item_put_on(): #I also saved global i from inventory_bag() for that
if all_item_names[i][1] == 'in hands':
item_left_hand.name = all_item_names[i][0]
elif all_item_names[i][1] == 'on head':
item_on_head.name = all_item_names[i][0]
但是通常的全局变量（不是对象）工作得很好：
global item_left_hand, item_on_head #in all functions
# below code is in item_put_on(): #I also saved global i from inventory_bag() for that
if all_item_names[i][1] == 'in hands':
item_left_hand = all_item_names[i][0]
elif all_item_names[i][1] == 'on head':
item_on_head = all_item_names[i][0]
