Dixi - Deep Dictionaries for Python

Installation

pip install dixi

Examples

from dixi import Dixi

data = Dixi({
    'Chris': {
        'age': 25,
        'address': {
            'city': 'Amsterdam',
            'country': 'Netherlands',
        },
    },
    'Anna': {
        'age': 19,
        'address': {
            'city': 'Zürich',
            'country': 'Switzerland',
        },
    },
    'John': {
        'age': 44,
        'address': {
            'city': 'London',
            'country': 'United Kingdom',
        },
    },
})

Deep indexing

data['John', 'age']
# >> 44

Partial indexing

data['Chris', 'address']
# >> {'city': 'Amsterdam', 'country': 'Netherlands'}

NumpPy style slicing

data[:, 'address', 'country']
# >> Dixi({'Chris': 'Netherlands', 'Anna': 'Switzerland', 'John': 'United Kingdom'})
data[['Chris', 'Anna'], 'age']
# >> {'Chris': 25, 'Anna': 19}

Setting

data['Derek', 'hobbies'] = ['Sewing', 'Archery']

Iteration

for key in data: # or key in data.leafkeys()
    print(key)
# >> ('Chris', 'age')
# >> ('Anna', 'age')
# >> ('Anna', 'address', 'city')
# >> ('Anna', 'address', 'country')
# >> ('John', 'age')
# >> ('John', 'address', 'city')
# >> ('John', 'address', 'country')
# >> ('Derek', 'hobbies')

for key in data.keys():
    print(key)
# >> Chris
# >> Anna
# >> John
# >> Derek

for key, value in data.items():
    print(key, value)
# >> Chris {'age': 25}
# >> Anna {'age': 19, 'address': {'city': 'Zürich', 'country': 'Switzerland'}}
# >> John {'age': 44, 'address': {'city': 'London', 'country': 'United Kingdom'}}
# >> Derek {'hobbies': ['Sewing', 'Archery']}

for keys, value in data.iterleaves():
