5.6.1 好玩游戏的物品清单

inventorys = {'rope': 1, 'torch': 6, 'gold coin': 42, 'dagger': 1, 'arrow': 12}


def displayInventory(inventorys):
	sumcount = 0
	print("Inventory:")
	for k, v in inventorys.items():
		print(v, "\t", k)
		sumcount += v
	print("Total number of items: %i" % sumcount)


displayInventory(inventorys)

5.6.2 列表到字典的函数，针对好玩游戏物品清单

dragonLoot = ['gold', 'dagger', 'gold', 'gold', 'ruby']
inventorys = {'rope': 1, 'torch': 6, 'gold': 42, 'dagger': 1, 'arrow': 12}


def addToInventory(inventorys, addedItems):
	for item in addedItems:
		inventorys.setdefault(item, 0)
		inventorys[item] += 1
		displayInventory(inventorys)


def displayInventory(inventorys):
	sumcount = 0
	print("Inventory:")
	for item, number in inventorys.items():
		print(item, "\t\t", number)
		sumcount += number
	print("Total number of items: %i" % sumcount)


addToInventory(inventorys, dragonLoot)
