Special contexts that apply to both: list(), sorted(), tuple() set(), any(), all(), sum(). Note: iter(d.keys()) could be written as iter(d) but since the original d.iterkeys() was also redundant we don't fix this. And there are (rare) contexts where it makes a difference (e.g. when passing it as an argument to a function that introspects the argument). � )�pytree)�patcomp)�token)� fixer_base)�Name�Call�LParen�RParen�ArgList�Dot)� fixer_util�iterc @ s^ e Z d Z d Z d Z d d � Z d Z e j e � Z d Z e j e � Z d d � Z d S) �FixDictTa power< head=any+ trailer< '.' method=('keys'|'items'|'values'| 'iterkeys'|'iteritems'|'itervalues'| 'viewkeys'|'viewitems'|'viewvalues') > parens=trailer< '(' ')' > tail=any* > c C s� | d } | d d } | d } | j } | j } | j d � } | j d � } | s^ | rq | d d � } n | d k s� t t | � � � d d � | D� } d d � | D� } | o� | j | | � } | t j | j t � t | d | j �g � | d j � g } t j | j | � } | p-| s`d | _ t t | rKd n d � | g � } n | r�t j | j | g | � } n | j | _ | S)N�head�method� �tailr Zview� �keys�items�valuesc S s g | ] } | j � � q S� )�clone)�.0�nr r �;/opt/alt/python34/lib64/python3.4/lib2to3/fixes/fix_dict.py� <listcomp>B s z%FixDict.transform.<locals>.<listcomp>c S s g | ] } | j � � q Sr )r )r r r r r r C s �prefixZparens� �list)zkeyszitemszvalues)�syms�value� startswith�AssertionError�repr�in_special_contextr ZNodeZtrailerr r r r Zpowerr ) �self�node�resultsr r r r Z method_name�isiterZisviewZspecial�args�newr r r � transform7 s4 ' zFixDict.transformz3power< func=NAME trailer< '(' node=any ')' > any* >zmfor_stmt< 'for' any 'in' node=any ':' any* > | comp_for< 'for' any 'in' node=any any* > c C s� | j d k r d Si } | j j d k r� | j j | j j | � r� | d | k r� | rm | d j t k S| d j t j k Sn | s� d S| j j | j | � o� | d | k S)NFr' �func)�parent�p1�matchr! � iter_exemptr �consuming_calls�p2)r& r' r) r( r r r r% [ s zFixDict.in_special_contextN) �__name__� __module__� __qualname__Z BM_compatibleZPATTERNr, ZP1r Zcompile_patternr/ ZP2r3 r% r r r r r * s r N)�__doc__r r r Zpgen2r r r r r r r r r r2 r1 ZBaseFixr r r r r �<module> s .
