我正在為一個學校項目編寫這段代碼，它是這樣的：valid_entries = ['y', 'n', 'hatchback', 'estate', 'saloon']model_options = { 'Hatchback' : 535000, 'Saloon' : 495000, 'Estate' : 625000}total_price = 0model_chosen = input("Which car model do you want to buy?\n> ")while model_chosen not in valid_entries: print("Invalid Input\nTry again") model_chosen = input("Which car model do you want to buy?\n> ")有沒有辦法可以訪問這些值并將其與輸入進行比較并將其添加到分數中？

您可以使用以下語法訪問該值：dict[key]。例如，在您的代碼中，models_options[Estate] 的值為 625000。您實際上并不需要列表 valid_entries。您可以嘗試以下代碼：
valid_entries = ['y', 'n', 'hatchback', 'estate', 'saloon']
model_options = {
'Hatchback' : 535000,
'Saloon' : 495000,
'Estate' : 625000
}
total_price = 0
model_chosen = input("Which car model do you want to buy?\n> ")
while model_chosen not in model_options:
print("Invalid Input\nTry again")
model_chosen = input("Which car model do you want to buy?\n> ")
total_price+=model_options[model_chosen]
print(total_price)

值為 model_options[model_chosen]，你到底想做什么？你能做到嗎：total += model_options[model_chosen]。
