As a special case, map(None, X) is changed into list(X). (This is necessary because the semantics are changed in this case -- the new map(None, X) is equivalent to [(x,) for x in X].) We avoid the transformation (except for the special case mentioned above) if the map() call is directly contained in iter(<>), list(<>), tuple(<>), sorted(<>), ...join(<>), or for V in <>:. NOTE: This is still not correct if the original code was depending on map(F, X, Y, ...) to go on until the longest argument is exhausted, substituting None for missing values -- like zip(), it now stops as soon as the shortest argument is exhausted. i ( t token( t fixer_base( t Namet Callt ListCompt in_special_context( t python_symbolst FixMapc B s# e Z e Z d Z d Z d � Z RS( s� map_none=power< 'map' trailer< '(' arglist< 'None' ',' arg=any [','] > ')' > > | map_lambda=power< 'map' trailer< '(' arglist< lambdef< 'lambda' (fp=NAME | vfpdef< '(' fp=NAME ')'> ) ':' xp=any > ',' it=any > ')' > > | power< 'map' trailer< '(' [arglist=any] ')' > > s future_builtins.mapc C s� | j | � r d S| j j t j k rh | j | d � | j � } d | _ t t d � | g � } n d | k r� t | d j � | d j � | d j � � } n� d | k r� | d j � } n� d | k r4| d } | j t j k r4| j d j t j k r4| j d j d k r4| j | d � d Sn t | � rDd S| j � } d | _ t t d � | g � } | j | _ | S( Ns You should use a for loop hereu u listt map_lambdat xpt fpt itt map_nonet argt arglisti t Nonesj cannot convert map(None, ...) with multiple arguments because map() now truncates to the shortest sequence( t should_skipt parentt typet symst simple_stmtt warningt clonet prefixR R R R t childrenR t NAMEt valueR R ( t selft nodet resultst newt args( ( s- /usr/lib64/python2.7/lib2to3/fixes/fix_map.pyt transform; s6 ( t __name__t __module__t Truet BM_compatiblet PATTERNt skip_onR ( ( ( s- /usr/lib64/python2.7/lib2to3/fixes/fix_map.pyR s N( t __doc__t pgen2R t R t fixer_utilR R R R t pygramR R t ConditionalFixR ( ( ( s- /usr/lib64/python2.7/lib2to3/fixes/fix_map.pyt <module> s "
