- sovabids.dicts.deep_get(dictionary, keys, default=None, sep='.')[source]¶
Safe nested dictionary getter.
- Parameters
dictionary (dict) – The dictionary from which to get the value.
keys (str) – The nested keys using sep as separator. Ie: ‘person.name.lastname’ if `sep`=’.’
default (object) – The default value to return if the key is not found
sep (str, optional) – The separator to indicate nesting/branching/hierarchy.
- Returns
The value of the required key. default if the key is not found.
- Return type
object
Notes
- sovabids.dicts.deep_merge_N(l)[source]¶
Merge the list of dictionaries, such that the latest one has the greater precedence.
- Parameters
l (list of dict) – List containing the dictionaries to be merged, having precedence on the last ones.
- Returns
The merged dictionary.
- Return type
dict
- sovabids.dicts.deep_merge(a, b)[source]¶
Merge two values, with b taking precedence over a.
Semantics: - If either a or b is not a dictionary, a will be returned only if
b is None. Otherwise b will be returned.
- If both values are dictionaries, they are merged as follows:
Each key that is found only in a or only in b will be included in the output collection with its value intact.
For any key in common between a and b, the corresponding values will be merged with the same semantics.

- Parameters
a (object) –
b (object) –
- Returns
Merged dictionary.
- Return type
dict
- sovabids.dicts.flatten(d, parent_key='', sep='.')[source]¶
Flatten the nested dictionary structure using the given separator.
If parent_key is given, then that level is added at the start of the tree.
- Parameters
d (dict) – The dictionary to flat.
parent_key (str, optional) – The optional top-level field of the dictionary.
sep (str, optional) – The separator to indicate nesting/branching/hierarchy.
- Returns
A dictionary with only one level of fields.
- Return type
dict
- sovabids.dicts.nested_notation_to_tree(key, value, leaf='.')[source]¶
Create a nested dictionary from the single (key,value) pair, with the key being branched by the leaf separator.
- Parameters
key (str) – The key/field to be nested, assuming nesting is represented with the “leaf” parameters.
value (object) – The value that it will have at the last level of nesting.
leaf (str, optional) – The separator used to indicate nesting in “key” parameter.
- Returns
Nested dictionary.
- Return type
dict
