Python class（輸入名稱，output編號）

Question

我想創建將輸出產品獎品總和的代碼。 下面的例子。

Input:
bread,rice

Output:
6,5 $

這是我的代碼：

class product:
def __init__(self,name,color,prize)
    self.name=name
    self.color=color
    self.prize=prize
def info(self)
    input(name)
    return (self.prize) 
tomato=product()
tomato.name="tomato"
tomato.color="czerwony"
tomato.prize= 4,56
 
turnip=product()
turnip.name="turnip"
turnip.color="white"
turnip.prize= 5.65
 


print("write the name of one products from the list and I will tell you how much it costs [tomato,turnip] "
info()

只有 2 個產品，我想減少代碼行。

我認為您正在尋找類似的東西，請注意，下面的代碼沒有任何錯誤/驗證檢查：

class product:
    def __init__(self,name=None,color=None,prize=None):
            self.name=name
            self.color=color
            self.prize=prize
    def info(self):
            return (self.prize)
tomato=product()
tomato.name="tomato"
tomato.color="czerwony"
tomato.prize= 4.56

turnip=product()
turnip.name="turnip"
turnip.color="white"
turnip.prize= 5.65


user_input = raw_input("write the name of one products from the list and I will tell you how much it costs [tomato,turnip]:")

print(eval(user_input).info())
