🎈🌵 Deflate Dict

Python package to deflate 🌵 and re-inflate 🎈 nested dictionaries.

How do I install this package?

As usual, just download it using pip:

pip install deflate_dict

Deflating a dictionary

A dictionary will be deflated down to its smallest non-further iterable elements, defined as those not containing lists or dictionaries.

from deflate_dict import deflate
D = {
    "a": [
        {
            "b": (0, 1, 2)
        },
        {
            "c": [1, 2, 3]
        }
    ]
}
result = deflate(D, sep="_")

# {'str(a)_listIndex(0)_str(b)': (0, 1, 2), 'str(a)_listIndex(1)_str(c)': [1, 2, 3]}

Inflate a dictionary

To reinflate a dictionary to its forgotten glory, just go with:

from deflate_dict import inflate
D = {"a_0_b": (0, 1, 2), "a_1_c": [1, 2, 3], "d": 4}

result = inflate(D, sep="_")

# {'a': [{'b': (0, 1, 2)}, {'c': [1, 2, 3]}], 'd': 4}

Handling and restoring mixed types

To deflate and re-inflate mixed types and restore them to the original type you can use the type_encode_key keyword:

from deflate_dict import deflate

D = {
    "a":[
        {
            "b":(0,1,2)
        },
        {
            "c": [1,2,3]
        }
    ]
}

print(deflate(D, sep="_", type_encode_key=False))

# {
# 'a_listIndex(0)_b': (0, 1, 2),
# 'a_listIndex(1)_c': [1, 2, 3]
# }

print(deflate(D, sep="_", type_encode_key=True))

# {
#    'str(a)_listIndex(0)_str(b)': (0, 1, 2),
#    'str(a)_listIndex(1)_str(c)': [1, 2, 3]
# }
