We avoid the transformation if the filter() 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 filter(F, X) to return a string if X is a string and a tuple if X is a tuple. That would require type inference, which we don't do. Let Python 2.6 figure it out. � )� fixer_base)�Node)�python_symbols)�Name�ArgList�ListComp�in_special_contextc @ s e Zd ZdZdZdZdd� ZdS )� FixFilterTaV filter_lambda=power< 'filter' trailer< '(' arglist< lambdef< 'lambda' (fp=NAME | vfpdef< '(' fp=NAME ')'> ) ':' xp=any > ',' it=any > ')' > [extra_trailers=trailer*] > | power< 'filter' trailer< '(' arglist< none='None' ',' seq=any > ')' > [extra_trailers=trailer*] > | power< 'filter' args=trailer< '(' [any] ')' > [extra_trailers=trailer*] > zfuture_builtins.filterc C s2 | j |�rd S g }d|kr:x |d D ]}|j|j� � q$W d|kr�t|jd�j� |jd�j� |jd�j� |jd�j� �}ttj|g| dd�}n�d|kr�ttd �td �|d j� td ��}ttj|g| dd�}nTt |�r�d S |d j� }ttjtd �|gdd�}ttjtd �t |g�g| �}d|_ |j |_ |S )NZextra_trailersZ filter_lambda�fp�itZxp� )�prefixZnoneZ_f�seq�args�filter�list) Z should_skip�appendZcloner �getr �symsZpowerr r r r )�selfZnodeZresultsZtrailers�t�newr � r �0/usr/lib64/python3.6/lib2to3/fixes/fix_filter.py� transform: s4 zFixFilter.transformN)�__name__� __module__� __qualname__Z BM_compatibleZPATTERNZskip_onr r r r r r s r N)�__doc__r r Zpytreer Zpygramr r Z fixer_utilr r r r ZConditionalFixr r r r r �<module> s
