如何在字典中存儲值

Question

袋子包含：

['Item','item','item']

硬幣包含：

['Item','Item','Item']

coin_to_bag = {}
print('Here are your bags:\n')
print(bags)
print('\n')
print('Here are your coin types:\n')
print (coins)

我的嵌套循環

bags =  ['small', 'medium','large']
coins = ['quarter', 'dime', 'nickel', 'penny']


'''
what Im trying to do:
foreach bag in bags:
    print: enter in a coin index. e.g. 1 for quarter out of ['quarter', 'dime', 'nickel', 'penny']
    prompt:: how many of this type?         15  (thus will store '15' representing, there are 15 quarters, storing '15')
    for index_position in coins:
        assign index, type = bag            create a dictionary like ["quarter"] = {"1", "15"}}
    print(coin_to_bag)      

'''
for bag in bags:
    coin_to_bag = coin_to_bag[bag]   # set quarter as a key in coin_to_bag = {["quarter"]}
    coin_type = input('Number of this type? e.g. type 1 for Quarter "["Quarter", "Nickel"]" ')  #e.g. 0.25 * 2
    coin_amount = input('Number of this type?   e.g. 15')  #e.g. 0.25 * 2
    for coin in coins:
        #set values for key: quarter like {["quarter"] = ["1", "15"]}
        coin_to_bag[bag] = coin_to_bag[coin_type], coin_to_bag[coin_amount]  

print(coin_to_bag)

我似乎無法弄清楚如何使用dictionary和lists(coin,bags)

最終，我試圖將coin_to_bag存儲：

coin_to_bag = {"small": {"1", "15"}, "medium": {"2", "5"}  }

Answer 1

值通過以下方式存儲到字典中：

some_dict = {}
some_dict[key] = value

或一行為： some_dict = {key: value} 。

因此，大概您想要：

coin_to_bag[bag] = [coin_type, coin_amount]

例如，這可能意味着

coin_to_bag['small'] = ["1", "15"]

這樣做， coin_to_bag[bag]意味着使用bag給出的密鑰訪問coin_to_bag字典的元素。 但是該鍵值在您進行設置之前不會存在。
