match SimpleProducer sendmessages with key docs and code

[c19]

http://kafka-python.readthedocs.org/en/latest/usage.html#keyed-messages

producer.send_messages(b'my-topic', b'key1', b'some message')
originally will two None key messages (None, 'key1') (None, 'some message')
fixed send with key would be:
producer.send_messages(b'my-topic', b'some message', key=b'key1')

I think maybe the documentation is just confusing? the docstring for SimpleProducer.send_messages does say: All messages produced via this method will set the message 'key' to Null

For keyed messages you might try the KeyedProducer class.

Yes, I figured it out..
