I beginner PYTHON, met a JSON parsing problem, want to ask the great spirit, how to modify the code, thank you,

Terminal error:
Return the self. Scan_once (s, independence idx=_w (s, independence idx). The end ())
Simplejson. Errors. JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Web content, this should be a JSON schema, but I don't know why I can't use JSON parsing, you cannot convert a result,
