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(utoken(u fixer_base(uNameuCalluListCompuin_special_context(upython_symbolscBs2|EeZdZdZdZdZdd„ZdS(uFixMapué 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] ')' > > ufuture_builtins.mapcCs|j|ƒrdS|jjtjkrh|j|dƒ|jƒ}d|_tt dƒ|gƒ}n d|kr§t |djƒ|djƒ|djƒƒ}nÊd|krÆ|d jƒ}nŠd |kr4|d }|jtj kr4|j d jt jkr4|j d jd kr4|j|d ƒdSnt|ƒrDdS|jƒ}d|_tt dƒ|gƒ}|j|_|S(NuYou should use a for loop hereuulistu map_lambdauxpufpuitumap_noneuarguarglistiuNoneujcannot convert map(None, ...) with multiple arguments because map() now truncates to the shortest sequence(u should_skipuparentutypeusymsu simple_stmtuwarningucloneuprefixuCalluNameuListCompuarglistuchildrenutokenuNAMEuvalueuin_special_contextuNone(uselfunodeuresultsunewuargs((u:/opt/alt/python33/lib64/python3.3/lib2to3/fixes/fix_map.pyu transform;s6           uFixMap.transformNT(u__name__u __module__u __qualname__uTrueu BM_compatibleuPATTERNuskip_onu transform(u __locals__((u:/opt/alt/python33/lib64/python3.3/lib2to3/fixes/fix_map.pyuFixMapsuFixMapN(u__doc__upgen2utokenuu fixer_baseu fixer_utiluNameuCalluListCompuin_special_contextupygramupython_symbolsusymsuConditionalFixuFixMap(((u:/opt/alt/python33/lib64/python3.3/lib2to3/fixes/fix_map.pyus "
