Python 仓库系统的分类

我目前有一个仓库系统，据我所知不可能得到一个好的分拣系统。有不同的方法吗？您将如何解决它们

我试着用数量将它们按最大数量到最小数量进行排序，但在列表中后退一步后，我无法得到它们

def start(x, warehouse=[]):
 'x is correct until this point'
 item_name = input("whats the name of the product?")
 item_amount = input("Whats the amount you want to buy?")
 item=item_name+"="+item_amount
 item.replace(" ", "")
 warehouse.append(item)

 decision=input("Do you want to add more items? Y/N")

 if decision=="Y":
     start(x, warehouse)
 if decision=="N":
     for x in warehouse:
         print(x)
     print("Do you want them to be sorted? Y/N")

print("The only reason for this program to exist is, to help you with your shopping list :D")
x = 0
lager = [""]
start(x, warehouse)

我认为在您的情况下，最简单的方法是将所有项目和金额存储在元组列表中，如下所示：

def start(warehouse=[]):
   item_name = input("whats the name of the product? ").strip()
   item_amount = input("Whats the amount you want to buy? ").strip()

   warehouse.append((item_name,int(item_amount)))

   decision=input("Do you want to add more items? (Y/N) ")

   if decision=="Y":
       start(warehouse)
   if decision=="N":
       for x in sorted(warehouse,key=lambda x:x[1]):
           print("{}={}".format(*x))
       print("Do you want them to be sorted? Y/N")

不太清楚你在问什么。预期的输出是什么？您得到的输出是什么？也读
