如何将此字符串转换为字典

我正在尝试正则表达式 r"},\s\]"，但没有得到所需的结果。

How do I convert this string to a dictionary

I'm trying regex r"},\s\]", but didn't get the desired result.

首先，我们需要去掉所有尾随逗号：

_sample = sample.replace("\n", "").replace(" ", "").replace(",]", "]")

您也可以使用正则表达式：

import re

_sample = re.sub(r",(\s)+]", "]", sample)

然后使用 json.loads() 将其解析为字典。

import json

outcome = json.loads(_sample)

超越 OQ
如果我们也可能在字典的最后一个键值后面有尾随逗号：例如 {"var5": "1215.00",} 您可以将上面的代码更新为：

_sample = sample.replace("\n", "").replace(" ", "").replace(",}", "}").replace(",]", "]")

或者使用正则表达式：

regex = r"(,(\s)+]|,(\s)+})"

First we need to get rid of any trailing commas:

_sample = sample.replace("\n", "").replace(" ", "").replace(",]", "]")

You can also use regex for this:

import re

_sample = re.sub(r",(\s)+]", "]", sample)

Then use json.loads() to parse it into a dict.

import json

outcome = json.loads(_sample)

Beyond the OQ
If it is also possible that we'd have trailing commas after the last key-value of a dictionary: e.g. {"var5": "1215.00",} you can update the above code to:

_sample = sample.replace("\n", "").replace(" ", "").replace(",}", "}").replace(",]", "]")

Or with regex:

regex = r"(,(\s)+]|,(\s)+})"
