This is just standard string substitution (see 3.6.2 "String Formatting
Operations <http://docs.python.org/release/2.5.2/lib/typesseq-strings.html>).

You might use (given outfile = '/some/path'):

subprocess.call('scanimage -args- > %s' % outfile, shell = True)

Or are you actually trying to retrieve $HOME?
