Overview

deflatable-dict

A dictionary that can be flattened and re-inflated. Particularly useful if you're interacting with yaml, for example.

Build PyPI version

Installation

with pip:

pip install deflatable-dict

deflatable-dict does not have any dependencies beyond standard python libraries.

Instantiation

from deflatabledict import DeflatableDict

dd = DeflatableDict({
    "a": {
        "1": True,
        "2": False,
    },
    "b": 20,
})

dd["a.1"] # True
dd["a.2"] # False
dd["b"] # 20
dd["a"] # { "1": True, "2": False }

Deflation

A DeflatableDict can be deflated with .deflate(). This returns a standard dictionary object with flattened keys constructed by concatenating the nested keys with the DeflatableDict's delimiter. A DeflatableDict uses it's deflated form for its string representation.

Delimiter

A DeflatableDict can have it's delimiter specified by passing the desired delimiter as the sep parameter to the DeflatableDict constructor. By default the delimiter if ..

Inflation

A DeflatableDict will automatically inflate any values that are inserted into it. For example:

from deflatabledict import DeflatableDict

dd = DeflatableDict()
dd["a.1"] = True
dd["a.2"] = False

dd["a"] # { "1": True, "2": False }
