在JSON中创建动态层次结构树结构

Question

我正在尝试为JSON对象构建层次结构树。

这是我到目前为止所拥有的：

nested_dict = lambda: defaultdict(nested_dict)
leaf = nested_dict()

root = {}
root["data"] = {"id": "Release"}
root["children"] = []

for (a, b, c, d) in zip(frame["a"], frame["b"], frame["c"], frame["d"]):
    leaf[a][b][c] = d

for a in leaf:
    root["children"].append({"data": {"id": a}})

print(root)

这对第一片叶子都很好，结果看起来像这样：

{
    "data": {
        "id": "Release"
    },
    "children": [
        {
            "data": {
                "id": "content of a"
            }
        },
        {
            "data": {
                "id": "content of a"
            }
        },
        {
            "data": {
                "id": "content of a"
            }
        }
    ]
}

现在我想带孩子到a。 这是我的尝试：

nested_dict = lambda: defaultdict(nested_dict)
leaf = nested_dict()

root = {}
root["data"] = {"id": "Release"}
root["children"] = []

for (a, b, c, d) in zip(frame["a"], frame["b"], frame["c"], frame["d"]):
    leaf[a][b][c] = d

for a in leaf:
    root["children"].append({"data": {"id": a}})
    for b in leaf[a]:
        root["children"].append({"children": [{"data": {"id": b}}]})


print(root)

这是不想要的结果：

{
    "data": {
        "id": "Release"
    },
    "children": [
        {
            "data": {
                "id": "content of a"
            }
        },
        {
            "children": [
                {
                    "data": {
                        "id": "content of b"
                    }
                }
            ]
        },
        {
            "data": {
                "id": "content of a"
            }
        },
        {
            "children": [
                {
                    "data": {
                        "id": "content of b"
                    }
                }
            ]
        },
        {
            "children": [
                {
                    "data": {
                        "id": "content of b"
                    }
                }
            ]
        },
        {
            "data": {
                "id": "content of a"
            }
        },
        {
            "children": [
                {
                    "data": {
                        "id": "content of b"
                    }
                }
            ]
        },
        {
            "children": [
                {
                    "data": {
                        "id": "content of b"
                    }
                }
            ]
        }
    ]
}

我希望它看起来像这样：

{
  "data": {
    "id": "Release"
  },
  "children": [
    {
      "data": {
        "id": "content of a"
      },
      "children": [
        {
          "data": {
            "id": "content of b"
          },
          "children": [
            {
              "data": {
                "id": "content of c"
              }
            }
          ]
        },
        {
          "data": {
            "id": "content of b"
          },
          "children": [
            {
              "data": {
                "id": "content of c"
              }
            }
          ]
        }
      ]
    },
    {
      "data": {
        "id": "Content of a"
      },
      "children": [
        {
          "data": {
            "id": "content of b"
          },
          "children": [
            {
              "data": {
                "id": "content of c"
              }
            },
            {
              "data": {
                "id": "content of c"
              }
            },
            {
              "data": {
                "id": "content of c"
              }
            }
          ]
        },
        {
          "data": {
            "id": "content of b"
          },
          "children": [
            {
              "data": {
                "id": "content of c"
              }
            },
            {
              "data": {
                "id": "content of c"
              }
            }
          ]
        }
      ]
    }
  ]
}

一整天都在工作，现在我是如此的嵌套，我找不到出路。
