How can I do that?

What you probably want is to use the struct module:
http://docs.python.org/3/library/struct.html

You probably also want the open method and file objects:
http://docs.python.org/3/library/functions.html#open

It would help if you provided information about which Python version you
are using, and exactly what you mean by "I can't save a binary file using
'bytearray(')". Do you get a traceback, if so, copy it in your message,
along with actual code that produces your problem (preferably simplified,
but not too far).
