+ labels = [slabel for label + in self.file.readline()[1:].split(b',') + if (slabel := label.strip())]

             labels = [slabel for label
                       in self._file.readline()[1:].split(b',')
                       for slabel in [label.strip()]
                       if slabel]

+ lines = [match.group(1, 2) + for rawline in rawlines + if (match := linepat.search(rawline.strip()))]

     lines = [match.group(1, 2)
              for raw_line in raw_lines
              for match in [line_pat.search(raw_line.strip())]
              if match]

But in all these cases I prefer the original loop.
