python-construct - A powerful declarative parser/builder for binary data
Construct is a powerful declarative parser (and builder) for binary
Instead of writing imperative code to parse a piece of data, you
declaratively define a data structure that describes your data. As

parse data into Pythonic objects, and in the other direction, convert
(build) objects into binary data.
