Python Client built against the Wolfram|Alpha v2.0 API. This project is hosted on Github.

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).
