如何使用Python

Question

我正在使用一些复杂的JSON文件，我需要读取所有值并在它们遇到某个字符串时重命名它们。

问题是JSON文件在字典里面的列表中包含字典......非常疯狂。这是一个例子：

{
    "key1": {
        "subkey11": "KeepMe1",
        "subkey12": "ChangeMe2"
    },
    "key2": [],
    "key3": [],
    "key4": [
        {
            "subkey41": "ChangeMe41",
            "subkey42": "KeepMe42",
            "subkey43": "ChangeMe43",
            "subkey44": [
                {
                    "subkey441": "ChangeMe441",
                    "subkey442": "KeepMe442"
                }
            ]
        }
    ]
}

我如何递归地读取所有内容以获取值并在需要时重命名它们？

我对此感到非常疯狂。提前谢谢！

如果你将json字符串转换为python dict对象会更容易。

import json

data = """
{
    "key1": {
        "subkey11": "KeepMe1",
        "subkey12": "ChangeMe2"
    },
    "key2": [],
    "key3": [],
    "key4": [
        {
            "subkey41": "ChangeMe41",
            "subkey42": "KeepMe42",
            "subkey43": "ChangeMe43",
            "subkey44": [
                {
                    "subkey441": "ChangeMe441",
                    "subkey442": "KeepMe442"
                }
            ]
        }
    ]
}
"""
print json.loads(data)

输出： -

{u'key3': [], u'key2': [], u'key1': {u'subkey11': u'KeepMe1', u'subkey12': u'ChangeMe2'}, u'key4': [{u'subkey44': [{u'subkey441': u'ChangeMe441', u'subkey442': u'KeepMe442'}], u'subkey43': u'ChangeMe43', u'subkey42': u'KeepMe42', u'subkey41': u'ChangeMe41'}]}
