• lod: List of dictionaries [{"a":1,"b":2}, {"a":3,"b":4}]
• lood: List of ordered dictionaries (OrderedDicts from collections module) [OrderedDict([('a', 1), ('b', 2)]), OrderedDict([('a', 3), ('b', 4)])]
• lol: List of lists [[1, 2, 3], [4, 5, 6]]
• dod: Dictionary of dictionaries {'key2': {'a': 1, 'b': 2}, 'key1': {'a': 1, 'b': 2}}
• lod_ymv: List of dictionaries with year-month-value keys [{'year': 2021, 'month': 1, 'value': 12.12}, {'year': 2023, 'month': 3, 'value': 13.03}]
• lod_xyv: List of dictionaries with x-y-value keys [{'X': 21, 'Y': 12, 'value': 180}, {'X': 2, 'Y': 122, 'value': 170}]

LOD

lod_has_key

Returns a boolean. Checks if list of dictionaries has a key

>>> from pydicts.lod import lod_has_key
>>> lod=[{"a":1, "b":4},{"a":2, "b":5}]
>>> lod_has_key(lod,"a")
True
>>> lod_has_key(lod,"d")
False
>>> lod_has_key([],"d")
False

lod_print

Prints a list of dictionaries in a tabulated way

>>> from pydicts.lod import lod_print
>>> lod=[{"a":1, "b":4},{"a":2, "b":None}]
>>> lod_print(lod)
+-----+-----+
|   a |   b |
|-----+-----|
|   1 |   4 |
|   2 |     |
+-----+-----+

lod_sum

Sums all values from a lod key. None values are ignored by default

>>> from pydicts.lod import lod_sum
>>> lod=[{"a":1, "b":4},{"a":2, "b":None}]
>>> lod_sum(lod,"a")
3
>>> lod_sum(lod,"b")
4
>>> lod_sum(lod,"b",ignore_nones=False)
