Question

所以我希望能够删除和添加我在游戏中尝试创建的库存中的项目，但我一直收到错误。这是我的代码：

inventory={}
def add_to_inventory():
    inventory.append()

elif choice == "use h on razor":
        print ("(pick up razor)")
        if "razor" in inventory:
            print ("You already got this item.")
            print ("")
            print ("Inventory: " + str(inventory))
        if "razor" not in inventory:
            print ("You walked over and picked up your razor blade.")
            print ("It's been added to your inventory.")
            add_to_inventory("razor")
            print("")
            print ("Inventory: " + str(inventory))
        game()

这是我在运行游戏时收到的错误：

    add_to_inventory("razor")
TypeError: add_to_inventory() takes 0 positional arguments but 1 was given

Answer 1

您的错误正在发生，因为add_to_inventory在函数定义中没有参数，但您尝试将'razor'作为参数传递给它。这就是TypeError: add_to_inventory() takes 0 positional arguments but 1 was given的含义。

此外，您正在使用列表append方法，但您正在将库存作为字典。

根据所需的功能，您可以使用以下两个选项：一个用于字典，另一个用于列表。

#DICTIONARY INVENTORY

from collections import defaultdict
inventory = defaultdict(int)

def add_to_inventory(item, amount):
    inventory[item] += amount

#LIST INVENTORY 

inventory = []
def add_to_inventory(item):
    inventory.append(item)

在我的基于文本的游戏中无法弄清楚我的库存有什么问题
