I think I understand what you want. Look at the struct module:

https://docs.python.org/2/library/struct.html

You can write/read binary data from files with standard means. Using 
struct, you can interpret or format integer values into a specific 
binary format. That would allow to create a reader or writer for a given 
binary format in Python.
