打印可用并显示两个词典中缺少的项目

Question

我有一个词典，里面包含我的冰箱中的食物，我想打印我可以制作的食谱，但如果我有足够的物品（显示丢失的物品数量），也可以打印出可以制作的食谱成分缺失，因此是什么成分。 我只是设法向他们展示了所有人。

fridge = {
    "orange" : 5,
    "citron" : 3,
    "sel" : 100,
    "sucre" : 50,
    "farine" : 250,
    "tomates" : 6,
    "huile" : 100,
    "pomme" : 1,
    "lait" : 1,
    "pois chiche" : 1,
}
    
recipes = {
    "jus_de_fruit" : {
        "orange" : 3,
        "citron" : 1,
        "pomme" : 2
    },
    "salad" : {
        "tomates" : 4,
        "huile" : 10,
        "sel" : 3
    },
    "crepes" : {
        "lait" : 1,
        "farine" : 250,
        "oeufs" : 2
        
    },
    "glace" : {
        "bac a glace" : 1,
        "coulis abricot" : 1,
        "batonnet" : 1
        }
    }

recette_dispo=[]
counter = 0
for recipe, recipe_contents in recipes.items():
     if all(elem in list(fridge.keys()) for elem in list(recipes[recipe].keys())):
        if all(recipe_contents[elem] <= fridge[elem] for elem in recipe_contents):
            print(f'\n \n ****   nice! you can make this recipe : {recipe}  ****')
            counter += 1 
            recette_dispo=recipe
        else : 
            print(f'You have all ingredients but not enough in quantity for: {recipe}, you need: {list(recipe_contents.items())}')           
  
     else :         
            print(f'\n\n Tu nas pas tous les ingrédients pour : {recipe}')
            print(f' You need these ingredients in order to make it  : {list(recipe_contents.items())}')
            

            
            
print("\n I can make in total", counter, "recipe(s) from the ingredients in my fridge:",recette_dispo)

输出：

You have all ingredients but not enough in quantity for: jus_de_fruit, you need:[('orange', 3), ('citron', 1), ('pomme', 2)]
#here I would like instead only the missing numbers of ingredients

     ****  nice! you can make this recipe : salad  ****
    
    
    You don't have all ingredients for: crepes
    You need these ingredients : [('lait', 1), ('farine', 250), ('oeufs', 2)]
#here I would like instead not all the ingredients of the recipe but only the ones missing in my fridge
    
    
     Tu nas pas tous les ingrédients pour : glace
     You need these ingredients: [('bac a glace', 1), ('coulis abricot', 1), ('batonnet', 1)]
    
     I can make in total 1recipe(s) from the ingredients in my fridge: salade

Answer 1

您可以使用此示例如何从冰箱中找到缺少的项目：

fridge = {
    "orange": 5,
    "citron": 3,
    "sel": 100,
    "sucre": 50,
    "farine": 250,
    "tomates": 6,
    "huile": 100,
    "pomme": 1,
    "lait": 1,
    "pois chiche": 1,
}

recipes = {
    "jus_de_fruit": {"orange": 3, "citron": 1, "pomme": 2},
    "salad": {"tomates": 4, "huile": 10, "sel": 3},
    "crepes": {"lait": 1, "farine": 250, "oeufs": 2},
    "glace": {"bac a glace": 1, "coulis abricot": 1, "batonnet": 1},
}

for recipe_name, ingredients in recipes.items():
    print(f"Recipe: {recipe_name}")
    if (missing := ingredients.keys() - fridge.keys()) :
        print("Missing ingredients:", missing)
    else:
        common = {
            k: fridge[k] - ingredients[k]
            for k in ingredients.keys() & fridge.keys()
        }

        if all(v >= 0 for v in common.values()):
            print("All ingredients are OK")
        else:
            for i, v in common.items():
                if v < 0:
                    print(f"Ingredient {i}: missing {-v} items")
    print("-" * 80)

打印：

Recipe: jus_de_fruit
Ingredient pomme: missing 1 items
--------------------------------------------------------------------------------
Recipe: salad
All ingredients are OK
--------------------------------------------------------------------------------
Recipe: crepes
Missing ingredients: {'oeufs'}
--------------------------------------------------------------------------------
Recipe: glace
Missing ingredients: {'batonnet', 'coulis abricot', 'bac a glace'}
--------------------------------------------------------------------------------

我试图实施类似于今年前（用汇编语言）类似的东西，但是作为一名采购代理（在前世）并没有为我提供更新我的冰箱，香料架的库存所需的勤奋程度。当我使用成分时。番茄酱，沙拉调味料，橄榄和切成薄片的泡菜等事情并不能很好地适合豆类。库存管理应适用于储藏室和深冰柜，并应在冰箱一级避免。

这只是我的看法，但是如果我们考虑到这一点并更多地依靠人类的触摸，我们可以通过使用sets ：

frigo = {
    "orange" : 5,
    "citron" : 3,
    "sel" : 100,
    "sucre" : 50,
    "farine" : 250,
    "tomates" : 6,
    "huile" : 100,
    "pomme" : 1,
    "lait" : 1,
    "pois chiche" : 1,
}

recettes = {
    "jus_de_fruit" : {
        "orange" : 3,
        "citron" : 1,
        "pomme" : 2
    },
    "salad" : {
        "tomates" : 4,
        "huile" : 10,
        "sel" : 3
    },
    "crepes" : {
        "lait" : 1,
        "farine" : 250,
        "oeufs" : 2
        
    },
    "glace" : {
        "bac a glace" : 1,
        "coulis abricot" : 1,
        "batonnet" : 1
        }
    }

frigoSet = set(frigo)
peutFaire = []
nePeutPasFaire = dict()

for recette in recettes:
    recetteSet = set(recettes[recette])
    recetteSet.difference_update(frigoSet)
    if len(recetteSet) == 0:
        peutFaire.append(recette)
    else:
        nePeutPasFaire.update({recette: list(recetteSet)})

print("Vous avez les ingrédients pour faire:")
for i in peutFaire:
    print("   {}".format(i))

print("\nIl manque des ingrédients pour les recettes suivantes:")
for i in nePeutPasFaire:
    print("   {}".format(i))
    for j in nePeutPasFaire[i]:
        print("      {}".format(j))

该程序的输出是：

Vous avez les ingrédients pour faire:
   jus_de_fruit
   salad

Il manque des ingrédients pour les recettes suivantes:
   crepes
      oeufs
   glace
      coulis abricot
      bac a glace
      batonnet

您可以 ：您可以：您可以：您可以：您可以：您可以：您可以：您可以：然后，使用您的个人个人了解您在冰箱中所拥有的知识来确定要制作的东西。毕竟，您可能会决定今天早上不做这些薄饼，因为明天您想节省几个鸡蛋。

这只是为了让您了解如何使用集合来获取基本信息，而无需通过从一开始就对每种食谱中的每种成分进行了很多比较。
