class_docstr: The GzipFile class simulates most of the methods of a file object with
  the exception of the truncate() method.
  
  This class only supports opening files in binary mode. If you need to open a
  compressed file in text mode, use the gzip.open() function.
docstr: Return the uncompressed stream file position indicator to the
  beginning of the file
docstr_tok: ["Return","the","uncompressed","stream","file","position","indicator","to","the","beginning","of","the","file"]
code: def rewind(self):
      """Return the uncompressed stream file position indicator to the
      beginning of the file"""
      if self.mode != READ:
          raise OSError("Can't rewind in write mode")
      self._buffer.seek(0)
