I wrote the below code

    def _Replace(match):
        return ((((2 * match.group(1)) + '"') + match.group(2)) + '"')
    segments = s.split('"')
    for i in range(0, len(segments), 2):
        segments[i] = delimiters_replacer_regex.sub(_Replace, segments[i])
    s = '"'.join(segments)
    if ((len(segments) % 2) == 0):
        print >>sys.stderr, (('Warning:    MSVS    may    misinterpret    the    odd    number    of    ' + 'quotes    in    ') + s)
    return s

What's a good function header?
 Can you provide a Python code to print >>sys?
