How do I process this using Python?

[Anthony Papillion]

Hello Everyone,

I'm writing a processor for Bitmessage messages and I am needing to
parse the following returned JSON string:

{u'inboxMessages': [{u'fromAddress':
u'BM-2DBYkhiBZCyrBa8J7gFRGrFRSGqtHgPtMvwQ', u'toAddress':
u'BM-2DC7SCTj2gzgrGgMvUCARdrfrsgLyz3iMyN3', u'read': 0, u'msgid':
u'36659a4453e12a085d8fbfeefc58da8fb23f38bfb0984c2983e0ddc31c776038',
u'receivedTime': u'1377986524', u'message':
u'dGVzdGluZyAxIDIgMw0KDQotLQ0KSm9obiBQZXJyeQ0KDQo=\n', u'encodingType':
2, u'subject': u'bWVzc2FnZSAx\n'}, {u'fromAddress':
u'BM-2DBYkhiBZCyrBa8J7gNBrngtgttHgPtMvwQ', u'toAddress':
u'BM-2DC7SCTj2gzgrGgMvUCARdCrfthyz3iMyN3', u'read': 0, u'msgid':

u'receivedTime': u'1377986557', u'message':
u'VGhpcyBpcyB0aGUgbmV4dCB0ZXN0DQoNCi0tDQpKb2huIFBlcnJ5DQoNCg==\n',
u'encodingType': 2, u'subject': u'dGVzdGluZyAzIDQgNQ==\n'},
{u'fromAddress': u'BM-2DBYkhithgyhyrBa8J7gNBrnSGqtHgPtMvwQ',
u'toAddress': u'BM-2DC7SCTj2gzgrtgtgMvUCARdCogLyz3iMyN3', u'read': 0,
u'msgid':
u'91dffd421c898aab0ffc43a363869a580abec6fa851aa6cf7cefe98263f96c81',
u'receivedTime': u'1377986599', u'message':
u'VGhpcyBpcyB0aGUgM3JkIHRlc3QNCg0hjj0NCkpvaG4gUGVycnkNCg0K\n',
u'encodingType': 2, u'subject': u'dGhpcyBpcyB0aGUgM3Jk\n'}]}

I tried using the following code:

data = json.loads(api.getAllInboxMessages) # This is the API call

for messageSender in data['inboxMessages']['fromAddress']
print messageSender

For some reason (probably obvious reasons) isn't working. I'm trying to
loop through the JSON and return all of the fromAddress fields.

Can anyone offer suggestions?

Thanks,
Anthony

Yes. Don't assume that "isn't working" is obvious. What do you mean
"isn't working"? What part isn't working? What does it do? Does it print
the wrong results, or does it raise an exception? If so, please copy and
paste the entire traceback, do not simplify it, summarise it, or retype
it from memory.
