{'channel':{'lastBuild':'2013-11-12', 'component':['test1', 'test2']}}
self.channel.component[0] => 'test1'

Use object_hook special parameter in load functions of json module:
import json
class JSONObject:
def __init__( self, dict ):
vars(self).update( dict )
#this is valid json string
data='{"channel":{"lastBuild":"2013-11-12", "component":["test1", "test2"]}}'
jsonobject = json.loads( data, object_hook= JSONObject)
print( jsonobject.channel.component[0] )
print( jsonobject.channel.lastBuild )
This method have some issue, like some names in python are reserved. You can filter them out inside __init__ method.

the json module will load a Json into a list of maps/list. e.g:
>>> import json
>>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
[u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
see http://docs.python.org/2/library/json.html
If you want to deserialize into a Class instance, see this SO thread: Parse JSON and store data in Python Class
