if the file format doesn't matter, use "pickle" or "marshal"
modules:

    mydata = ...

    file = open("myfile.dat", "wb")
    pickle.dump(mydata, file)
    file.close()

    ...

    file = open("myfile.dat", "rb")
    data = pickle.load(file)
    file.close()

to write data in a given binary format (e.g. if you want to
read it back from a C program), use the "struct" module.

for more info, see the library reference.
