替换嵌套列表和字典中的项目 [英] Replace items in a dict of nested list and dicts

问题描述

有什么解决方案可以用嵌套列表的 dict 中的特定值替换项目，而python中的dicts是否可用?

Is there any solution to replace items with a specific value in a dict of nested list and dicts in python ?

例如:

输入:

item_to_be_replaced =  'a'

replaced_with = 'z'

di = {"a": "A", "b": "B", "c": [2, 4, 6, {"a": "A", "b": "B"}], "d": {"a": [2, 4, 6], "b": [5, 2, 1]}}

输出:

{"z": "A", "b": "B", "c": [2, 4, 6, {"z": "A", "b": "B"}], "d": {"z": [2, 4, 6], "b": [5, 2, 1]}}

解决这个问题的最佳方法是什么?

which is the most optimal way to solve this problem ?

推荐答案

我不认为这是最好的选择，但是当我看到这个时，我就想到了这个答案:

I dont thing its the best option, but when i saw this i thought about this answer:

import json
json.loads(json.dumps(di).replace(f'"{item_to_be_replaced}"', f'"{replaced_with}"'))

简单地转换为字符串，替换我需要替换的东西，然后返回到 dict

Simple convert into string, replace the thing that i need to replace, and back to dict
