python程序-->列表到字典的函数，针对好玩游戏物品清单

首先，boss是一条龙，掉的装备如下

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

你的背包里面物品如下

inv = {'gold coin':42,'rope':1}

打完boss之后背包更新

重新更改背包物品及数量

效果如下

代码如下：

def addToInventory(inventory , addedItems ): # 更新背包
    print('背包更新中:')
    c1 = {}
    for something in addedItems:             #将传到的表格转换为字典，元素作为键，次数作为值                
        c1.setdefault(something,0)
        c1[something] +=1
    for v in inventory.keys(): 
        if v not in c1.keys():
            c1.setdefault(v,0)               #设置默认值，当这个元素存在，就用其本身的值，若不是，则用括号中所给的值
            c1[v] += inventory[v] 
    for k  in c1.keys():
        if k in inventory:
                c1[k] = c1[k] +inventory[k]
    return c1


def displayInventory(inv):        #打印字典，即打印背包的物品
    for k ,v in inv.items():
        print(str(v) +' '+ k )

inv = {'gold coin':42,'rope':1}
dragonLoot = ['gold coin','dagger','gold coin','gold coin','ruby']
print('背包物品：')
displayInventory(inv)
print('BOSS掉落物品：')
print(dragonLoot)
inv = addToInventory(inv,dragonLoot)
print('背包物品：')
displayInventory(inv)
