A file is a stream of bytes, but you want to view it as a stream of records. It sounds like you want an abstraction layer, and it sounds like you also want to let the file leak through that layer when it's convenient. (Yes, I spun that horribly on purpose, and I understand the use case of imposing some structure on part of a file, and possibly a different structure on a different part of a file. MIME messages and literate programming files spring to mind.) Perhaps (as I think ChrisA suggested), you could provide your own buffering/chunking layer between your application and the file itself, and never let the application see the file directly. -- https://mail.python.org/mailman/listinfo/python-list
