Is this script interactive?  I'm guessing not. In any case, the
recommended course for any Unix OS is to just use the tee command to
redirect the output both to the terminal and to a file.  Works with
anything that outputs text to standard out.

As for doing it in Python, maybe you can implement your own print-like
function that prints everything out twice. Once to the file and once to
std out.
