Jaccs allows you to pull data from JSON objects using string Python expressions. For example:
>>> from jaccs import access >>> access({'a': {'b': [{'c': 1}, {'c': 2}]}}, '_.a.b[1].c') 2
This is expected to be most useful for combining specifications stored in external text files (say JSON or YAML) with data objects in Python.
