使用正则表达式在python中的字符串中将Boolean true转换为True

我是python的新手。我有一个看起来像下面的字符串

 """[{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":false}},{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":true}},{"key":false,"doc":{"uniq_id":"false key","retail_price":799,"offer":true}}
]"""

我需要使用将其转换为字典列表ast。但它表明malformed string error，由于false在offer关键的。我知道python接受True为布尔值而不是true。所以我正在使用re模块将其转换为，False但是在字符串中，有更多false或true发生了它。
我需要字符串中所有唯一的布尔值到python布尔值。我不知道regex更改格式。为我提供一些解决方案。

import re, ast 
a= """[{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":false}},{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":true}},{"key":false,"doc":{"uniq_id":"false key","retail_price":799,"offer":true}}
]"""
a = ast.literal_eval(a)
print(a)

要求的输出：

[{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":False}},{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":True}},,{"key":False,"doc":{"uniq_id":"false key","retail_price":799,"offer":True}}
]

如上面评论部分所述，您应该改用jsonmodule，更具体地说json.loads：

>>> l="""[{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":false}},{"key":"aadsas","doc":{"uniq_id":"false key","retail_price":799,"offer":true}},{"key":false,"doc":{"uniq_id":"false key","retail_price":799,"offer":true}} ]"""
>>>
>>> import json
>>> json.loads(l)
[{'key': 'aadsas', 'doc': {'uniq_id': 'false key', 'retail_price': 799, 'offer': False}}, {'key': 'aadsas', 'doc': {'uniq_id': 'false key', 'retail_price': 799, 'offer': True}}, {'key': False, 'doc': {'uniq_id': 'false key', 'retail_price': 799, 'offer': True}}]
