将常用的 file.txt 格式转换为 Dictionaty 格式，嵌套字典 Python

你所做的只是从文件中读取，而你应该从中获取值并在字典中分配它。

cook_book = {}

indexes = []

with open('recipes.txt', 'r', encoding='utf-8') as fp:
    data = fp.read()
    linedData = data.split('\n')
    i = 0
    for line in data.split('\n'):
        try:
            amount = int(line)
            indexes.append(i)
            indexes.append(amount)
        except:
            pass
        i += 1
    for x in range(len(indexes)):
        if (x % 2) == 0:
            mealName = linedData[indexes[x]-1]
            focusedData = linedData[indexes[x] + 1:]
            focusedData = focusedData[:(indexes[x+1])]
            totalIngredients = []
            for line in focusedData:
                ingredients = {}
                try:
                    name, amm, ref = line.split(' | ')
                    ingredients['ingredient_name'] = name
                    ingredients['quantity'] = int(amm)
                    ingredients['measure'] = ref
                except:
                    pass
                totalIngredients.append(ingredients)
            cook_book[mealName] = totalIngredients

    print(cook_book)

创建以下输出：

{'Omelette': [{'ingredient_name': 'Egg', 'quantity': 2, 'measure': 'PCS'}, {'ingredient_name': 'Milk', 'quantity': 100, 'measure': 'ml'}, {'ingredient_name': 'Tomato', 'quantity': 2, 'measure': 'PCS'}], 'Peking duck': [{'ingredient_name': 'Duck', 'quantity': 1, 'measure': 'PCS'}, {'ingredient_name': 'Water', 'quantity': 2, 'measure': 'l'}, {'ingredient_name': 'Honey', 'quantity': 3, 'measure': 'tbsp'}, {'ingredient_name': 'Soy sauce', 'quantity': 60, 'measure': 'ml'}], 'Baked potatoes': [{'ingredient_name': 'Potatoes', 'quantity': 1, 'measure': 'kg'}, {'ingredient_name': 'Garlic', 'quantity': 3, 'measure': 'tooth'}, {'ingredient_name': 'Gouda cheese', 'quantity': 100, 'measure': 'G'}], 'Fajitos': [{'ingredient_name': 'Beef', 'quantity': 500, 'measure': 'G'}, {'ingredient_name': 'Sweet pepper', 'quantity': 1, 'measure': 'PCS'}, {'ingredient_name': 'Lavash', 'quantity': 2, 'measure': 'state'}, {'ingredient_name': 'Wine vinegar', 'quantity': 1, 'measure': 'tbsp'}, {'ingredient_name': 'Tomato', 'quantity': 2, 'measure': 'state'}]}

但是，当格式化时，它会创建所需的输出：

{
'Omelette': [
    {'ingredient_name': 'Egg', 'quantity': 2, 'measure': 'PCS'}, 
    {'ingredient_name': 'Milk', 'quantity': 100, 'measure': 'ml'}, 
    {'ingredient_name': 'Tomato', 'quantity': 2, 'measure': 'PCS'}
    ],
'Peking duck': [
    {'ingredient_name': 'Duck', 'quantity': 1, 'measure': 'PCS'}, 
    {'ingredient_name': 'Water', 'quantity': 2, 'measure': 'l'}, 
    {'ingredient_name': 'Honey', 'quantity': 3, 'measure': 'tbsp'}, 
    {'ingredient_name': 'Soy sauce', 'quantity': 60, 'measure': 'ml'}
    ], 
'Baked potatoes': [
    {'ingredient_name': 'Potatoes', 'quantity': 1, 'measure': 'kg'}, 
    {'ingredient_name': 'Garlic', 'quantity': 3, 'measure': 'tooth'}, 
    {'ingredient_name': 'Gouda cheese', 'quantity': 100, 'measure': 'G'}
    ], 
'Fajitos': [
    {'ingredient_name': 'Beef', 'quantity': 500, 'measure': 'G'}, 
    {'ingredient_name': 'Sweet pepper', 'quantity': 1, 'measure': 'PCS'}, 
    {'ingredient_name': 'Lavash', 'quantity': 2, 'measure': 'state'}, 
    {'ingredient_name': 'Wine vinegar', 'quantity': 1, 'measure': 'tbsp'}, 
    {'ingredient_name': 'Tomato', 'quantity': 2, 'measure': 'state'}
    ]
}

请记住，可能有更有效的方法来实现所需的输出，并且会有办法重构我的代码，但这是我对这个问题的尝试。

希望这会有所帮助。

嘿，也许比@Hunters解决方案短一点

with open('recipes.txt', 'r', encoding='utf-8') as recipes:
    cook_book = {}
    for line in recipes:
        if  (line.replace("\n", "")).isnumeric() or line == "\n":   # Ignore unwanted lines
            continue
        elif "|" not in line:   # Initialize individual recipes
            current_recipe = line.replace("\n", "")
            cook_book[current_recipe] = []
        elif len(line.strip("|")) > 2:  # Add ingredients
            ingredient = {}
            ingredient_lst = line.split("|")
            ingredient["ingredient_name"] = ingredient_lst[0].strip()
            ingredient["quantity"] = ingredient_lst[1].strip()
            ingredient["measure"] = ingredient_lst[2].replace("\n", "").strip()

            cook_book[current_recipe].append(ingredient)

print(cook_book)

如果您加载任何文件并从中读取，您应该始终使用 with 块 - Python 将自行处理关闭文件等。

编辑：

如果要将cook_book转储到 json 文件，可以添加以下内容

import json

with open('cook_book.json', 'w', encoding='utf-8') as f:
    json.dump(cook_book, f, ensure_ascii=False, indent=4)

结果如下：

{
    "Omelet": [
        {
            "ingredient_name": "Egg ",
            "quantity": " 2 ",
            "measure": " PCS"
        },
        {
            "ingredient_name": "Milk ",
            "quantity": " 100 ",
            "measure": " ml"
        },
        {
            "ingredient_name": "Tomato ",
            "quantity": " 2 ",
            "measure": " PCS"
        }
    ],
    "Peking Duck": [
        {
            "ingredient_name": "Duck ",
            "quantity": " 1 ",
            "measure": " PCS"
        },
        {
            "ingredient_name": "Water ",
            "quantity": " 2 ",
            "measure": " l"
        },
        {
            "ingredient_name": "Honey ",
            "quantity": " 3 ",
            "measure": " t.sp"
        },
        {
            "ingredient_name": "Soy sauce ",
            "quantity": " 60 ",
            "measure": " ml"
        }
    ]
}
