Python dictionary with dot notation

  • Partially compartible with python-box
  • Issue #87 of python-box fixed
  • Customization of key conversion
from diot import Diot

# Box is a conversion_box by default, pass in `conversion_box=False` to disable that behavior
# Explicitly tell Diot to convert dict/list inside
movie_diot = Diot(movie_data)

movie_diot.movies.Robin_Hood_Men_in_Tights.imdb_stars
# 6.7

movie_diot.movies.Spaceballs.stars[0].name
# 'Mel Brooks'

# Different as box, you have to use Diot for new data in a list
movie_diot.movies.Spaceballs.stars.append(
	Diot({"name": "Bill Pullman", "imdb": "nm0000597", "role": "Lone Starr"}))
movie_diot.movies.Spaceballs.stars[-1].role
# 'Lone Starr'

Install

pip install diot

Diot

Instantiated the same ways as dict

Diot({'data': 2, 'count': 5})
Diot(data=2, count=5)
Diot({'data': 2, 'count': 1}, count=5)
Diot([('data', 2), ('count', 5)])

# All will create
# Diot([('data', 2), ('count', 5)], diot_nest = True, diot_transform = 'safe')

Same as python-box, Diot is a subclass of dict which overrides some base functionality to make sure everything stored in the dict can be accessed as an attribute or key value.

diot = Diot({'data': 2, 'count': 5})
diot.data == diot['data'] == getattr(diot, 'data')

By default, diot uses a safe transformation to transform keys into safe names that can be accessed by diot.xxx

dt = Diot({"321 Is a terrible Key!": "yes, really"})
dt._321_Is_a_terrible_Key_
# 'yes, really'

Different as python-box, duplicate attributes are not allowed.

dt = Diot({"!bad!key!": "yes, really", ".bad.key.": "no doubt"})
# KeyError

Use different transform functions:

dt = Diot(oneTwo = 12, diot_transform = 'snake_case')
# or use alias:
# dt = SnakeDiot(oneTwo = 12)
dt.one_two == dt['one_two'] == dt['oneTwo'] == 12

dt = Diot(one_two = 12, diot_transform = 'camel_case')
# or use alias:
# dt = CamelDiot(one_two = 12)
dt.oneTwo == dt['one_two'] == dt['oneTwo'] == 12

dt = Diot(one_two = 12, diot_transform = 'upper')
dt.ONE_TWO == dt['one_two'] == dt['ONETWO'] == 12

dt = Diot(ONE_TWO = 12, diot_transform = 'lower')
dt.one_two == dt['ONE_TWO'] == dt['one_two'] == 12

Use your own transform function:

import inflection

dt = Diot(post = 10, diot_transform = inflection.pluralize)
dt.posts == dt['posts'] == dt['post'] == 10

OrderedDiot

diot_of_order = OrderedDiot()
diot_of_order.c = 1
diot_of_order.a = 2
diot_of_order.d = 3

list(diot_of_order.keys()) == ['c', 'a', 'd']

# insertion allowed for OrderedDiot
od = OrderedDiot()
od.insert(0, "c", "d")
od.insert(None, "x", "y")
od.insert_before('c', "e", "f")
od.insert_after("a", ("g", "h"))

od2 = OrderedDiot()
od2.a1 = 'b1'
od2.c1 = 'd1'
od.insert(-1, od2)

od3 = OrderedDiot()
od3.a2 = 'b2'
od3.c2 = 'd2'
od.insert_before('c', od3)
