:target: https://pypi.python.org/pypi/nested-lookup
A small Python library which enables key lookups on deeply nested documents.
Documents may be built out of dictionaries (dicts) and/or lists.
Make working with JSON, YAML, and XML document responses fun again!
.. contents::
install
========
install from pypi using pip::
pip install nested-lookup
or easy_install::
easy_install nested-lookup
or install from source using::
git clone https://github.com/russellballestrini/nested-lookup.git
cd nested-lookup
pip install .
tutorial
========
.. code-block:: python
>>> from nested_lookup import nested_lookup
>>> document = [ { 'taco' : 42 } , { 'salsa' : [ { 'burrito' : { 'taco' : 69 } } ] } ]
>>> print(nested_lookup('taco', document))
[42, 69]
wild
========
We also have a `wild` mode that treats the given `key` as a case insensitive
substring of all the keys in the document and returns any values which match.
For example:
.. code-block:: python
from nested_lookup import nested_lookup
my_document = {
'name' : 'Russell Ballestrini',
'email_address' : 'test1@example.com',
'other' : {
'secondary_email' : 'test2@example.com',
'EMAIL_RECOVERY' : 'test3@example.com',
},
},
results = nested_lookup(
key = 'mail',
document = my_document,
wild = True
)
print(results)
['test1@example.com', 'test2@example.com', 'test3@example.com']
output
========
There are two `output` modes:
- `list`: the function returns a list of values corresponding to the
matched keys.
- `dict`: the function returns a `dict` with the matched keys as keys and
their corresponding values as values.
For example:
.. code-block:: python
from nested_lookup import nested_lookup
my_document = {
'name' : 'Russell Ballestrini',
'email_address' : 'test1@example.com',
'other' : {
'secondary_email' : 'test2@example.com',
'EMAIL_RECOVERY' : 'test3@example.com',
},
},
results = nested_lookup(
key = 'mail',
document = my_document,
wild = True,
output = 'dict'
)
print(results)
{'email_address': 'test1@example.com',
'secondary_email': 'test2@example.com',
'EMAIL_RECOVERY': 'test3@example.com'}
