如何将此json字符串转换为dict？

Question

After executing the following code:

import json
a = '{"excludeTypes":"*.exe;~\\$*.*"}'
json.loads(a)

I get:

Traceback (most recent call last): File "", line 1, in File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/ init .py", line 338, in loads return _default_decoder.decode(s) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 365, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 381, in raw_decode obj, end = self.scan_once(s, idx) ValueError: Expecting property name: line 1 column 2 (char 1)

So how can I convert 'a' to dict. Please note that the string is already in 'a' and I cannot add 'r' in front of it. Ideally, the string should have been {"excludeTypes":"*.exe;~\\\\\\\\$*.*"}

Also, the following code doesn't work:

import json
a = '{"excludeTypes":"*.exe;~\\$*.*"}'
b = repr(a)
json.loads(b)

Answer 1

import ast

d = ast.literal_eval(a)

Answer 2

By escaping Escape Character "\\":

import json
a = '{"excludeTypes":"*.exe;~\\$*.*"}'
a = a.replace("\\","\\\\")
json.loads(a)
