Python项目：创建一个程序来跟踪向导可以携带的项目

Question

show不起作用，它不会显示我的任何项目

在代码的第一个文件中，我有以下内容：

在项目.py公司名称：

list(inventory_list):
inventory = ["a wooden staff", "a wizard hat", "a cloak of invisibility",

"some elven bread", "an unknown potion", "a scroll of uncursing",

"a scroll of invisibility", "a crossbow", "a wizard's cloak"]
item = inventory.pop()
item = inventory.pop(1)
item = inventory.pop(2)
item = inventory.pop(3)
item = inventory.pop(4)
item = invnetory.pop(5)
item = inventory.pop(6)
item = inventory.pop(7)
item = inventory.pop(8)

在我的另一个文件中主.py文件看起来像这样。在

^{pr2}$

另一个问题是我需要单独的文件还是可以把它们放在一个文件中？在

我觉得这更符合你的要求。另外，我会帮助你，因为我可以从你的代码中看到一些你正在挣扎的地方，但是请检查关于向SO发布问题的规则，因为正如前面提到的，这不符合配置文件。同时也要检查我的不同之处，并试图理解原因。在

inventory_list = []
