I wrote the below code

    ParseResult = namedtuple(u'ParseResult', (u'placeholder', u'filemode', u'filepath'))
    def parse_line(line):
        parts = tuple((x.strip(u'"\'') for x in shlex.split(line, posix=False)))
        if (len(parts) == 1):
            return ParseResult(PREFIX_PLACEHOLDER, FileMode.text, parts[0])
        elif (len(parts) == 3):
            return ParseResult(parts[0], FileMode(parts[1]), parts[2])
        else:
            raise CondaVerificationError((u'Invalid    has_prefix    file    at    path:    %s' % path))
    parsed_lines = (parse_line(line) for line in yield_lines(path))
    return {pr.filepath: (pr.placeholder, pr.filemode) for pr in parsed_lines}

What's a good function header?
 ... What is a Python code to fix    file    at    path:    %s' % path))?
