'module' object has no attribute 'loads' while parsing JSON using python

It looks like you have a json.py module which is not part of the Standard Library. Not sure what ZookPython is. Try renaming ZookPython directory (or just json.py) and re-run.

File "json.py", line 2, in <module>
  import json

This line is a giveaway: you have named your script "json", but you are trying to import the builtin module called "json", since your script is in the current directory, it comes first in sys.path, and so that's the module that gets imported.

You need to rename your script to something else, preferrably not a standard python module.
