这是我的 json 对象

[  {    "person": "abc",    "city": "united states",    "facebooklink": "link",    "united states": [      {        "person": "cdf",        "city": "ohio",        "facebooklink": "link",        "ohio": [          {            "person": "efg",            "city": "clevland",            "facebooklink": "link",            "clevland": [              {                "person": "jkl",                "city": "street a",                "facebooklink": "link",                "street a": [                  {                    "person": "jkl",                    "city": "house 1",                    "facebooklink": "link"                  }                ]              }            ]          },          {            "person": "ghi",            "city": "columbus",            "facebooklink": "link"          }        ]      },      {        "person": "abc",        "city": "washington",        "facebooklink": "link"      }    ]  }]

我想创建以下 json，将地址字段动态添加到 json 中。

[  {    "person": "abc",    "city": "united states",    "facebooklink": "link",    "address": "united states",    "united states": [      {        "person": "cdf",        "city": "ohio",        "facebooklink": "link",        "address": "united states/ohio",        "ohio": [          {            "person": "efg",            "city": "clevland",            "facebooklink": "link",            "address": "united states/ohio/clevland",            "clevland": [              {                "person": "jkl",                "city": "Street A",                "facebooklink": "link",                "address": "united states/ohio/clevland/Street A",                "Street A": [                  {                    "person": "jkl",                    "city": "House 1",                    "facebooklink": "link",                    "address": "united states/ohio/clevland/Street A/House 1"                  }                ]              }            ]          },          {            "person": "ghi",            "city": "columbus",            "facebooklink": "link",            "address": "united states/ohio/columbus"          }        ]      },      {        "person": "abc",        "city": "washington",        "facebooklink": "link",        "address": "united states/washington"      }    ]  }]``How can I achieve this in Python.

正确答案

我已经尽力解决了。看看这是否有帮助。用短json编写代码。但您可以使用完整的嵌套 json 作为输入。

# import jsongiven_data = [  {    "person": "abc",    "city": "united states",    "facebooklink": "link",    "united states": [      {        "person": "cdf",        "city": "ohio",        "facebooklink": "link"      },      {        "person": "abc",        "city": "washington",        "facebooklink": "link"      }    ]  }]PARENT_TOP = ""city = "city"address = 'address'def update_address(parent_node, my_path=PARENT_TOP):    if isinstance(parent_node, list):        for child_node in parent_node:            if isinstance(child_node, dict):                city = child_node.get("city")                new_path = f"{my_path}/{city}" if my_path else city                child_node[address] = new_path                grand_child = child_node.get(city)                update_address(grand_child, new_path)    elif isinstance(parent_node, dict):        city = parent_node.get("city")        new_path = f"{my_path}/{city}" if my_path else city        parent_node[address] = new_path        child = parent_node.get(city)        update_address(child, new_path)    else:        pass    return parent_nodeif __name__ == '__main__':    update_address(given_data)    # output = json.dumps(json.loads(str(given_data)), indent=2)    print(given_data)
