I would recommend NumPy for manipulating binary data. It is primarily
intended for numerics, but it is excellent for dealing with any kind
of binary data as well. It can handle mutable buffers of any kind of
integer or float, as well as arrays of C-like structs (record arrays
in numpy). You can typecast and create subarrays without copying any
data, simply by providing a new "view" into the buffer. You can also
get access to strided subsections without creating copies. And it is
very fast.
