overscore

Library for double underscore access notation

Overscore provides a way to retrieve (and store) multi-dimensional data using a single string with double underscores.

Inspired by Django, the access string can be used as a routine argument or a URL parameter, allowing for complex access within simple contexts:

import overscore

data = {
    "things": {
        "a": {
            "b": [
                {
                    "1": "yep"
                }
            ]
        }
    }
}

overscore.get(data, "things__a__b__0____1")
# "yep"

All keys/indexes are separated by double underscores. Extra underscores dictate how to parse that place in the path.
