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
