Dictionary types that make it easier to work trees of nested dictionaries.
Consider a nested regular dictionaries::
d = {
"en": {
"gb": "English (United Kingdom)",
"us": "English (United States)",
"ca": "English (Canada)",
"za": "English (South Africa)",
},
"no": {
"nb": "Norwegian (Bokmål)",
"nn": "Norwegian (Nynorsk)",
},
"fr": {
"be": "French (Belgium)",
"ca": "French (Canada)",
"fr": "French (Standard)",
"ch": "French (Switzerland)",
}
}
from which we can construct a ``DeepDict``::
>>> from dendrodict import DeepDict
>>> languages = DeepDict(d)
Nested dictionaries can be accessed with single application of the square brackets get-item
operator::
>>> languages["fr", "ca"]
'French (Canada)'
or by using a tuple as a key::
>>> languages[("no", "nb")]
'Norwegian (Bokmål)'
The tuple key can also be used with other dictionary methods, such as ``get()``::
>>> languages.get(("en", "us"))
'English (United States)'
It's still possible index the inner dictionary levels::
>>> languages["en"]
DeepDict(
{
'gb': 'English (United Kingdom)',
'us': 'English (United States)',
'ca': 'English (Canada)',
'za': 'English (South Africa)'
}
)
which means that separate lookup operations are still supported::
>>> languages["en"]["za"]
'English (South Africa)'
The tuple key form can also be used on construction, so flat dictionaries with tuple keys will be
expanded into nested dictionaries. Consider the following single-level mapping of tuple keys to
values::
blocks = {
("mineral", "sandstone", "block"): "Sandstone",
("mineral", "sandstone", "chiseled"): "Sandstone (Chiseled)",
("mineral", "cobblestone", "block"): "Cobblestone",
("mineral", "cobblestone", "slab"): "Cobblestone (Slab)",
("mineral", "gold", "ore"): "Gold Ore",
("wood", "birch", "block"): "Birch",
("wood", "birch", "slab"): "Birch-Wood Slab",
("wood", "oak", "block"): "Oak",
("wood", "oak", "plank"): "Wooden Plank (Oak)",
}
Created a ``DeepDict`` from this, gives a three-level structure::
>>> minecraft = DeepDict(blocks)
which we can see by converted back to dictionaries using the ``to_dict()`` method::
>>> minecraft.to_dict()
{'mineral': {
'cobblestone': {
'block': 'Cobblestone',
'slab': 'Cobblestone (Slab)'
},
'gold': {
'ore': 'Gold Ore'
},
'sandstone': {
'block': 'Sandstone',
'chiseled': 'Sandstone (Chiseled)'
}
},
'wood': {
'birch': {
'block': 'Birch',
'slab': 'Birch-Wood Slab'
},
'oak': {
'block': 'Oak',
'plank': 'Wooden Plank (Oak)'}
}
}
Particularly when dealing with configuration data, it can be useful to be able to use dotted names
for access to nested items. Use ``DottedDeepDict`` for this::
from dendrodict import DottedDeepDict
displays = DottedDeepDict(
{
"resolution": {
"vga": {
"width": 640,
"height": 480,
},
"wxga": {
"width": 1280,
"height": 800,
},
"wqhd": {
"width": 2560,
"height": 1440,
},
}
}
)
Dotted name syntax can be used for lookup::
>>> displays["resolution.vga.width"]
640
or for assignment at arbitrary levels::
>>> displays["resolution.1080p.width"] = 1920
>>> displays["resolution.1080p.height"] = 1080
Shallower levels are still available individually::
>>> displays["resolution.1080p"]
DottedDeepDict({'width': 1920, 'height': 1080})
and can be converted back to regular dictionaries::
>>> displays["resolution.wqhd"].to_dict()
{'width': 2560, 'height': 1440}
