array problems.. OverflowError

[Chris Lambacher]

You probably want to look at using struct.pack.  That will allow you
to back heterogenious groups of data into a string that can be saved
to disk or sent over the network.  It also does a really good job of
taking care of byte order for you(if you tell it to).
