I wonder if there is a way to decode a JSON-like string.
I got string:
'{ hotel: { id: "123", name: "hotel_name"} }'
It's not a valid JSON string, so I can't decode it directly with the python API. Python will only accept a stringified JSON string like:
'{ "hotel": { "id": "123", "name": "hotel_name"} }'
where properties are quoted to be a string.
Use demjson module, which has ability to decode in non-strict mode.
In [1]: import demjson
In [2]: demjson.decode('{ hotel: { id: "123", name: "hotel_name"} }')
Out[2]: {u'hotel': {u'id': u'123', u'name': u'hotel_name'}}
@vartec has already pointed out demjson, which works well for slightly invalid JSON. For data that's even less JSON compliant I've written barely_json:
from barely_json import parse
print(parse('[no, , {complete: yes, where is my value?}]'))
prints
[False, '', {'complete': True, 'where is my value?': ''}]
You could try and use a wrapper for a JavaScript engine, like pyv8.
import PyV8
ctx = PyV8.JSContext()
ctx.enter()
# Note that we need to insert an assignment here ('a ='), or syntax error.
js = 'a = ' + '{ hotel: { id: "123", name: "hotel_name"} }'
a = ctx.eval(js)
a.hotel.id
>> '123' # Prints
Not very elegant and not robust (and easy to break), but it may be possible to kludge it with something like:
kludged = re.sub('(?i)([a-z_].*?):', r'"\1":', string)
# { "hotel": { "id": "123", "name": "hotel_name"} }
You may find that using pyparsing and the parsePythonValue.py example could do what you want as well... (or modified fairly easily to do so) or the jsonParser.py could be modified to not require quoted key values.
