Python将使用正则表达式解析数据转化为字典。

我有一串数据。我想把它变成一个 字典

ff = '{wrapper:{one:{now:""},up:"north",down:"south"}}'

请注意，这些键不是用“或”包装的文本。正则表达式可以帮助做到这一点吗？新文本应该如下所示。如果熊猫可以做到这一点，我可以 使用熊猫

ff = '{"wrapper":{"one":{"now":""},"up":"north","down":"south"}}' 

使用环视：

(?<={).*?(?=:)

（？
（？！”）
-负面展望

def st_to_dict(st):
    import re
    return re.sub(r'(\b[^:"]+\b)(?!")',r'"\1"',st)

ff = '{wrapper:{one:{now:""},up:"north",down:"south"}}'

print(st_to_dict(ff))

输出：

{"wrapper":{"one":{"now":""},"up":"north","down":"south"}}

def st_to_dict(st):
    import re
    return re.sub(r'(\b[^:"]+\b)(?!")',r'"\1"',st)

ff = '{wrapper:{one:{now:""},up:"north",down:"south"}}'

print(st_to_dict(ff))

{"wrapper":{"one":{"now":""},"up":"north","down":"south"}}
