converting string to dictionary using json.loads

Question

I'm trying to pass some json data extracted from a JavaScript file.

I have the following variable in my python code. I get the string from file.read(). I know the below will be set as a dict if pasted into a python code as is.

resultStr = {"inst":{"summary":{"statistics":[],"wa_recursive":"100.000%","files":11,"dus":11}},"du":{"summary":{"statistics":[{"type":"stmt","data":"Statement Coverage","status":"covered","weight":1,"rhits":"100.000%","rtotal":"100.000%"},{"data":"Statements","rhits":86.000,"rtotal":86.000},{"data":"Subprograms","rhits":0.000,"rtotal":0.000},{"type":"branch","data":"Branch Coverage","status":"covered","weight":1,"rhits":"100.000%","rtotal":"100.000%"},{"data":"Branch paths","rhits":42.000,"rtotal":42.000},{"data":"Branches","rhits":21.000,"rtotal":21.000},{"type":"toggle","data":"Toggle Coverage","status":"uncovered","weight":1,"rhits":"94.410%","rtotal":"100.000%"},{"data":"Toggle bins","rhits":304.000,"rtotal":322.000},{"data":"Signal bits","rhits":150.000,"rtotal":161.000}],"wa_recursive":"98.137%","files":11,"dus":11}}};

When i pass this string into the json loader

json.loads(resultStr)

I get the following exception

  File "C:\Python34\lib\json\__init__.py", line 318, in loads
    return _default_decoder.decode(s)
  File "C:\Python34\lib\json\decoder.py", line 346, in decode
    raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 1 column 825 - line 1 column 826 (char 824 - 825)

To simplify its failing on the last part of the string

"wa_recursive":"98.137%","files":11,"dus":11}}};

I've tried to just enter it manually and it is recognized as a dictionary in the python code.

I cant seem to find any fault with it so some assistance would be appreciated :)

Thank you :)

The thing your passing to json.loads is a dictionary, not a string. I don't get any error when I load it by the way. Did you put the semicolon in the string? — Andreas Argelius

the value is a string IE resultStr is reported as a string. I might have shown it wrong but the value i have i get from a file.read(). ITs correct i also get a dict if I just paste the above into my code. — Ephreal

The following works fine for me. Did you keep the semicolon in the string?

import json
resultStr = '{"inst":{"summary":{"statistics":[],"wa_recursive":"100.000%","files":11,"dus":11}},"du":{"summary":{"statistics":[{"type":"stmt","data":"Statement Coverage","status":"covered","weight":1,"rhits":"100.000%","rtotal":"100.000%"},{"data":"Statements","rhits":86.000,"rtotal":86.000},{"data":"Subprograms","rhits":0.000,"rtotal":0.000},{"type":"branch","data":"Branch Coverage","status":"covered","weight":1,"rhits":"100.000%","rtotal":"100.000%"},{"data":"Branch paths","rhits":42.000,"rtotal":42.000},{"data":"Branches","rhits":21.000,"rtotal":21.000},{"type":"toggle","data":"Toggle Coverage","status":"uncovered","weight":1,"rhits":"94.410%","rtotal":"100.000%"},{"data":"Toggle bins","rhits":304.000,"rtotal":322.000},{"data":"Signal bits","rhits":150.000,"rtotal":161.000}],"wa_recursive":"98.137%","files":11,"dus":11}}}'
decodedData = json.loads(resultStr);
print(decodedData);
