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�ArgList�Call�ListComp�in_special_context)�python_symbols)�Nodec � � e Zd ZdZdZdZd� Zy)�FixMapTaL map_none=power< 'map' trailer< '(' arglist< 'None' ',' arg=any [','] > ')' > [extra_trailers=trailer*] > | map_lambda=power< 'map' trailer< '(' arglist< lambdef< 'lambda' (fp=NAME | vfpdef< '(' fp=NAME ')'> ) ':' xp=any > ',' it=any > ')' > [extra_trailers=trailer*] > | power< 'map' args=trailer< '(' [any] ')' > [extra_trailers=trailer*] > zfuture_builtins.mapc � � | j |� ry g }d|v r)|d D ]! }|j |j � � �# |j j t j k( rA| j |d� |j � }d|_ t t d� |g� }�n�d|v rbt |d j � |d j � |d j � � }t t j |g|z d� � }�nbd |v r |d j � }d|_ �n d |v r�|d }|j t j k( r�|j d j t j k( rs|j d j d j t" j$ k( r<|j d j d j& dk( r| j |d� y t t j t d� |j � g� }d|_ t) |� ry t t j t d� t+ g� g|z � }d|_ |j |_ |S )N�extra_trailersz You should use a for loop here� �list� map_lambda�xp�fp�it)�prefix�map_none�arg�args� � �Nonezjcannot convert map(None, ...) with multiple arguments because map() now truncates to the shortest sequence�map)� should_skip�append�clone�parent�type�syms� simple_stmt�warningr r r r r �power�trailer�children�arglistr �NAME�valuer r )�self�node�results�trailers�t�newr s �</opt/alt/python312/lib64/python3.12/lib2to3/fixes/fix_map.py� transformzFixMap.transform@ s � � � � �D� !� ��� �w� &� � -�.�������� �*� /� �;�;� � �t� /� /� /� �L�L�� ?� @��*�*�,�C��C�J��t�F�|�c�U�+�C� �W� $��7�4�=�.�.�0�"�4�=�.�.�0�"�4�=�.�.�0�2�C� �t�z�z�C�5�8�#3�B�?�C� �W�$� �e�n�*�*�,�� �� ��W�$�"�6�?�D��y�y�D�L�L�0��}�}�Q�'�,�,�� � �<��}�}�Q�'�0�0��3�8�8�E�J�J�F��}�}�Q�'�0�0��3�9�9�V�C� � � �T� ,N� O� � �t�z�z�D��K���� �+F�G�C�!#�C�J�%�d�+� ��t�z�z�D��L�'�3�%�.�#A�H�#L�M�C��C�J��[�[�� �� � N)�__name__� __module__� __qualname__� BM_compatible�PATTERN�skip_onr3 � r4 r2 r r s � ��M��G�: $�G�.r4 r N)�__doc__�pgen2r r r � fixer_utilr r r r r �pygramr r# �pytreer �ConditionalFixr r; r4 r2 �<module>rB s2 ���& � � J� J� +� �P�Z� &� &� Pr4
