Here's a brief recap: For each SET_LINENO instruction after the first one, two bytes are added to lnotab. (In some cases, multiple two-byte entries are added.) The first byte is the distance in bytes between the instruction for the last SET_LINENO and the current SET_LINENO. The second byte is offset in line numbers. If either offset is greater than 255, multiple two-byte entries are added -- see compile.c for the delicate details. c C s: g | _ d | _ d | _ d | _ d | _ g | _ d S( Ni ( t codet codeOffsetR� t lastlinet lastoffR� ( R ( ( s( /usr/lib64/python2.7/compiler/pyassem.pyR Z s c G sA x$ | D] } | j j t | � � q W| j t | � | _ d S( N( R� R6 t chrR� R ( R Rd RT ( ( s( /usr/lib64/python2.7/compiler/pyassem.pyR� b s c C s | j d k r$ | | _ | | _ n� | j | j } | | j } | d k r| j j } x. | d k r� | d � | d � | d 8} q\ Wx4 | d k r� | | � | d � | d 8} d } q� W| d k s� | d k r� | | � | | � n | | _ | j | _ n d S( Ni i� ( R� R� R� R� R� R6 ( R t linenot addrt linet push( ( s( /usr/lib64/python2.7/compiler/pyassem.pyR� g s* c C s d j | j � S( NR?
