Thanks for explaining.  I would rephrase as follows:

  Attempt to find the range of program counter addresses for the
  @code{line} attribute of the @code{Symtab_and_line} object.  If
  found, return a @code{Tuple} containing the start and end addresses
  for the line.  Otherwise (e.g., a line with no corresponding code or
  not present in the debug info), return @code{None}.
