In visitAugAssign, the left-hand expression node is visited twice. The first time the visit uses the normal method for that node . The second time the visit uses a different method that generates the appropriate code to perform the assignment. These delegator classes wrap the original AST nodes in order to support the variant visit methods. c C s | | _ d S( N( t obj( R; R ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR< � s c C s t | j | � S( N( R� R ( R; t attr( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyt __getattr__� s ( RB RC Ri R< R ( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR � s t AugGetattrc B s e Z RS( ( RB RC ( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR � s t AugNamec B s e Z RS( ( RB RC ( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR � s t AugSlicec B s e Z RS( ( RB RC ( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR s t AugSubscriptc B s e Z RS( ( RB RC ( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyR s c C s t | j | � S( N( t wrapperRw ( R_ ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyRk s t __main__(M RR RK RJ RN t syst cStringIOR t compilerR R R R R R R R t compiler.constsR R R R R R R R R R R R R R t compiler.pyassemR t version_infoRJ t AttributeErrorR� R� R� R� R� R+ R/ R# R: R2 R1 R" RT Rm Rn R� RF RD RE R� R� R R� R� R� Rc R R R R R R t Getattrt Namet Slicet SubscriptR Rk RB t argvt file( ( ( s7 /opt/alt/python27/lib64/python2.7/compiler/pycodegen.pyt <module> s� ""(@ + � � � � U>
