python如何組合兩個串列（鍵/值對），其中包含字典串列

我有兩個串列，每個串列都有多個專案。這是示例：

X：

[
    {
        "uuid": "b9e9d655-64a8-4d74-a9bc-3967347f7928",
        "name": "general_c",
        "generation": 0,
        "root_provider_uuid": "b9e9d655-64a8-4d74-a9bc-3967347f7928",
        "parent_provider_uuid": null
    },
    {
        "uuid": "94d3d093-3608-4cf1-982b-3897ed77d59a",
        "name": "aggr",
        "generation": 1,
        "root_provider_uuid": "94d3d093-3608-4cf1-982b-3897ed77d59a",
        "parent_provider_uuid": null
    },
    {
        "uuid": "59758b2f-8faa-4eae-b838-a31fcc40c2c2",
        "name": "c001",
        "generation": 961,
        "root_provider_uuid": "59758b2f-8faa-4eae-b838-a31fcc40c2c2",
        "parent_provider_uuid": null
    }
]

第一：

[
    [],
    [
        {
            "resource_class": "VCPU",
            "allocation_ratio": 16.0,
            "min_unit": 1,
            "max_unit": 64,

        },
        {
            "resource_class": "MEMORY_MB",
            "allocation_ratio": 1.5,
            "min_unit": 1,
            "max_unit": 257653,

        }
    ],
    [
        {
            "resource_class": "VCPU",
            "allocation_ratio": 4.0,
            "min_unit": 1,
            "max_unit": 64,

        },
        {
            "resource_class": "MEMORY_MB",
            "allocation_ratio": 2.0,
            "min_unit": 1,
            "max_unit": 257589,

        }
    ]
]

所需的輸出：

新串列：

[
    {
        "uuid": "b9e9d655-64a8-4d74-a9bc-3967347f7928",
        "name": "general_c",
        "generation": 0,
        "root_provider_uuid": "b9e9d655-64a8-4d74-a9bc-3967347f7928",
        "parent_provider_uuid": null
        "resource_allocation: []"
    },
    {
        "uuid": "94d3d093-3608-4cf1-982b-3897ed77d59a",
        "name": "aggr",
        "generation": 1,
        "root_provider_uuid": "94d3d093-3608-4cf1-982b-3897ed77d59a",
        "parent_provider_uuid": null
        "resource_allocation: 
                [
                    {
                        "resource_class": "VCPU",
                        "allocation_ratio": 16.0,
                        "min_unit": 1,
                        "max_unit": 64,
            
                    },
                    {
                        "resource_class": "MEMORY_MB",
                        "allocation_ratio": 1.5,
                        "min_unit": 1,
                        "max_unit": 257653,
            
                    }
                ]
    },
    {
        "uuid": "59758b2f-8faa-4eae-b838-a31fcc40c2c2",
        "name": "c001",
        "generation": 961,
        "root_provider_uuid": "59758b2f-8faa-4eae-b838-a31fcc40c2c2",
        "parent_provider_uuid": null
        "resource_allocation: 
                [
                      {
                          "resource_class": "VCPU",
                          "allocation_ratio": 4.0,
                          "min_unit": 1,
                          "max_unit": 64,
                
                      },
                      {
                          "resource_class": "MEMORY_MB",
                          "allocation_ratio": 2.0,
                          "min_unit": 1,
                          "max_unit": 257589,
                
                      }
                  ]
    }
]

我想創建一個名為“resource_allocation”的新鍵并向其添加“lst”項值，如上所示

我正在嘗試這樣做：

x["resource_allocation"] = lst
print(x)

得到錯誤：

    x["resource_allocation"] = lst
TypeError: list indices must be integers or slices, not str

我確定我做錯了，有人可以建議我實作所需輸出的正確方法嗎？我看過SO帖子之前沒有遇到過這種要求。謝謝

uj5u.com熱心網友回復：

您試圖為串列分配一個鍵值，因此它會引發錯誤。您必須遍歷 x 串列并單獨分配鍵。

for i in range(len(x)):
    x[i]['resource_allocation']=lst[i]
print(json.dumps(x,indent=2))
