A function to map the keys in a dictionary
Project description
Map Dictionary Keys
Installation
pip install map-dictionary-keys
Usage
from map_dictionary_keys import map_dictionary_keys
d = {'some_key_to_map': 'value'}
mapped_dictionary = map_dictionary_keys(d, lambda key: key.upper())
In the above example, mapped_dictionary
will be mapped according to the function some_mapping_function
as follows:
mapped_dictionary = {'SOME_KEY_TO_MAP': 'value'}
This function will work for all levels of nested dictionaries. In the following example, both 'sub_dictionary'
and 'key_name'
will be converted as per the mapping function passed to map_dictionary_keys
.
dictionary = {
'sub_dictionary': {
'key_name': 'value'
}
}
It will also work for nested lists of dictionaries. For example, in the following example, 'key_name'
will be mapped according to the mapping function provided to map_dictionary_keys
.
dictionary = {
'list_of_dictionaries': [
{
'key_name': 'value'
}
]
}
This function will not currently work for lists nested beyond the first level. For example, in the following example, 'key_name'
will not be mapped according to the mapping function provided to map_dictionary_keys
.
dictionary = {
'my_list': [
[
{
'key_name': 'value'
}
]
]
}
