Python Client built against the `Wolfram|Alpha <http://wolframalpha.com>`_
v2.0 API. This project is hosted on `Github
<https://github.com/jaraco/wolframalpha>`_.
Usage
=====
Basic usage is pretty simple. Create the client with your App ID (request from
Wolfram Alpha)::
import wolframalpha
client = wolframalpha.Client(app_id)
Then, you can send queries, which return Result objects::
res = client.query('temperature in Washington, DC on October 3, 2012')
Result objects have `pods` (a Pod is an answer group from Wolfram Alpha)::
for pod in res.pods:
do_something_with(pod)
Pod objects have ``subpods`` (a Subpod is a specific response with the plaintext
reply and some additional info)::
for pod in res.pods:
for sub in pod.subpods:
print(sub.text)
You may also query for simply the pods which have 'Result' titles or are
marked as 'primary' using ``Result.results``::
print(next(res.results).text)
All objects returned are dictionary subclasses, so to find out which attributes
Wolfram|Alpha has supplied, simply invoke ``.keys()`` on the object.
Attributes formed from XML attributes can be accessed with or without their
"@" prefix (added by xmltodict).
