Question

    sellers = ["amazon", "walmart", "Target", "CVS",  "Walgreens", "macys", "kohls"]

    data = [
        {
        "price": "21",
        "title": "Laura Geller Iconic Baked Sculpting Lipstick, Red Overfl",
        "seller": "kohls",
        },
        {
        "price": "21.00",
        "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
        "seller": "amazon"
        },
        {
            "price": "21.00",
            "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
            "seller": "macys"
        },
        {
            "price": "21.00",
            "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
            "seller": "walmart"
        }
    ]

这是我的数据。我想按照上述列表按卖方对我的数据进行排序。实际的列表必须是动态的。

请看看我该如何实现。

    [
        {
            "price": "21.00",
            "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
            "seller": "amazon"
        },
        {
            "price": "21.00",
            "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
            "seller": "walmart"
        },
        {
            "price": "21.00",
            "title": "Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream",
            "seller": "macys"
        },
        {
        "price": "21",
        "title": "Laura Geller Iconic Baked Sculpting Lipstick, Red Overfl",
        "seller": "kohls",
        }
    ]

请看看

Answer 1

您可以使用sorted()

res = sorted(data, key=lambda x: sellers.index(x['seller']))

print(res)

输出：

[{'price': '21.00',
  'title': 'Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream',
  'seller': 'amazon'},
 {'price': '21.00',
  'title': 'Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream',
  'seller': 'walmart'},
 {'price': '21.00',
  'title': 'Laura Geller Beauty Iconic Baked Sculpting Lipstick - Cream',
  'seller': 'macys'},
 {'price': '21',
  'title': 'Laura Geller Iconic Baked Sculpting Lipstick, Red Overfl',
  'seller': 'kohls'}]

python按项目列表对字典进行排序
