Hi,in python3 my variable looks like this: a = b'{"uuid":"5730e8666ffa02.34177329","error":""}' str(a) = 'b\'{"uuid":"5730e8666ffa02.34177329","error":""}\'' If I execute the following command I get the error:json.loads(str(a))Traceback (most recent call last): File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.1.2\helpers\pydev\_pydevd_bundle\pydevd_exec2.py", line 3, in Exec exec(exp, global_vars, local_vars) File "<input>", line 1, in <module> File "C:\Program Files\Python34\lib\json\__init__.py", line 318, in loads return _default_decoder.decode(s) File "C:\Program Files\Python34\lib\json\decoder.py", line 343, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Program Files\Python34\lib\json\decoder.py", line 361, in raw_decode raise ValueError(errmsg("Expecting value", s, err.value)) from None ValueError: Expecting value: line 1 column 1 (char 0) Why I am getting this error? If I set variable a to the '{"uuid":"5730e8666ffa02.34177329","error":""}' everything works as expected.
This means that the two versions of 'a' are not the same. So what you should have done to debug is print the second to see what you actually passed to json.
Editorial: Programming classes should teach basic debugging better. I have seen numerous newbie Stackoverflow questions where the person should have started with adding a print statement before posting a question.
