列出游戏库存的字典功能-用Python自动化无聊的东西-chapter5

想象一下，被征服的龙的战利品被表示为这样的字符串：

dragonLoot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']

编写一个名为的函数addToInventory(inventory, addedItems)，其中inventory参数是表示玩家的库存的字典（如上一个项目中所示），addedItems参数是一个列表dragonLoot。该addToInventory()函数应该返回一个表示更新的库存的字典。请注意，该addedItems列表可以包含相同项目的倍数。你的代码看起来像这样：

# inventory.pydef displayInventory(inventory):    print("Inventory:")    item_total = 0    for k, v in inventory.items():        item_total=item_total+v        print(k+' :',v)    print("Total number of items: " + str(item_total))#stuff = {'rope': 1, 'torch': 6, 'gold coin': 42, 'dagger': 1, 'arrow': 12}#displayInventory(stuff)'''输出如下：Inventory:12 arrow42 gold coin1 rope6 torch1 daggerTotal number of items: 62'''def addToInventory(inventory, addedItems):    # your code goes here    for k,v in inventory.items():        if addedItems in inventory:            v=v+addedItems.get(item,0)        else:    return inventoryinv = {'gold coin': 42, 'rope': 1}dragonLoot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']inv = addToInventory(inv, dragonLoot)displayInventory(inv)

输出结果如下：

Inventory:45 gold coin1 rope1 ruby1 daggerTotal number of items: 48
