qmk-dotty-dict 1.3.0.post1

Features

• Simple wrapper around python dictionary and dict like objects

• Two wrappers with the same dict are considered equal

• Access to deeply nested keys with dot notation: dot['deeply.nested.key']

• Create, read, update and delete nested keys of any length

• Expose all dictionary methods like .get, .pop, .keys and other

• Access dicts in lists by index dot['parents.0.first_name']

• key=value caching to speed up lookups and low down memory consumption

• support for setting value in multidimensional lists

• support for accessing lists with slices

Waiting for your feature requests ;)

Quick Example

Create new dotty using factory function.

>>> from dotty_dict import dotty
>>> dot = dotty({'plain': {'old': {'python': 'dictionary'}}})
>>> dot['plain.old']
{'python': 'dictionary'}

You can start with empty dotty

>>> from dotty_dict import dotty
>>> dot = dotty()
>>> dot['very.deeply.nested.thing'] = 'spam'
>>> dot
Dotty(dictionary={'very': {'deeply': {'nested': {'thing': 'spam'}}}}, separator='.', esc_char='\\')

>>> dot['very.deeply.spam'] = 'indeed'
>>> dot
Dotty(dictionary={'very': {'deeply': {'nested': {'thing': 'spam'}, 'spam': 'indeed'}}}, separator='.', esc_char='\\')

>>> del dot['very.deeply.nested']
>>> dot
Dotty(dictionary={'very': {'deeply': {'spam': 'indeed'}}}, separator='.', esc_char='\\')

>>> dot.get('very.not_existing.key')
None

NOTE: Using integer in dictionary keys will be treated as embedded list index.

Testing

$ make test-all

Limitations

In some very rare cases dotty may not work properly.

• When nested dictionary has two keys of different type, but with the same value. In that case dotty will return dict or list under random key with passed value.

• Keys in dictionary may not contain dots. If you need to use dots, please specify dotty with custom separator.

• Nested keys may not be bool type. Bool type keys are only supported when calling keys with type defined value (e.g. dot[True], dot[False]).
