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. � )�token)� fixer_base)�Name�Call�ListComp�in_special_context)�python_symbolsc @ s. e Z d Z d Z d Z d Z d d � Z d S)�FixMapTa� 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] ')' > > zfuture_builtins.mapc C s~ | j | � r d S| j j t j k rh | j | d � | j � } d | _ t t d � | g � } nd | k r� t | d j � | d j � | d j � � } n� d | k r� | d j � } n� d | k r1| d } | j t j k r1| j d j t j k r1| j d j d k r1| j | d � d St | � rAd S| j � } d | _ t t d � | g � } | j | _ | S)Nz You should use a for loop here� �listZ map_lambdaZxp�fp�itZmap_none�arg�arglist� �Nonezjcannot convert map(None, ...) with multiple arguments because map() now truncates to the shortest sequence)Z should_skip�parent�type�symsZ simple_stmtZwarningZclone�prefixr r r r Zchildrenr �NAME�valuer )�selfZnodeZresults�new�args� r �:/opt/alt/python35/lib64/python3.5/lib2to3/fixes/fix_map.py� transform; s6 zFixMap.transformN)�__name__� __module__� __qualname__Z BM_compatibleZPATTERNZskip_onr r r r r r s r N)�__doc__Zpgen2r r r Z fixer_utilr r r r Zpygramr r ZConditionalFixr r r r r �<module> s "
