python always compiles everything to bytecode before
it executes it (and caches the result in .pyc files). you
don't have to do anything to get that behaviour...

if you insist on compiling things yourself, use the
"compile" (!) function:

    filename = "module.py"
    source = open(filename).read()
    code = compile(source, filename, "exec")
    exec code # run it

the marshal module allows you to serialize code
objects:

    data = marshal.dumps(code) # convert to string
    code = marshal.loads(data) # and back
    exec code # run it again

pyc files are simply serialized code objects, plus a small
header.  see the py_compile module for details.
