a �DOg� � @ sj d Z ddlmZ ddlmZ ddlmZ ddlmZmZmZ ddlmZ ej dhB Z G dd � d ej �Z d S ) aj Fixer for dict methods. d.keys() -> list(d.keys()) d.items() -> list(d.items()) d.values() -> list(d.values()) d.iterkeys() -> iter(d.keys()) d.iteritems() -> iter(d.items()) d.itervalues() -> iter(d.values()) d.viewkeys() -> d.keys() d.viewitems() -> d.items() d.viewvalues() -> d.values() Except in certain very specific contexts: the iter() can be dropped when the context is list(), sorted(), iter() or for...in; the list() can be dropped when the context is list() or sorted() (but not iter() or for...in!). 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)� fixer_base)�Name�Call�Dot)� fixer_util�iterc @ s@ e Zd ZdZdZdd� ZdZe�e�Z dZ e�e �Z dd� 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}|�d�}|�d�} |sD| rP|dd � }|dv sdJ t|���d d � |D �}d d � |D �}| o�| �||�} |t�|jt� t ||j d �g�|d � � g } t�|j | �} | s�| s�d| _ t t |r�dnd�| g�} |�rt�|j | g| �} |j | _ | S )N�head�method� �tailr �view� )�keys�items�valuesc S s g | ] }|� � �qS � ��clone��.0�nr r �./usr/lib64/python3.9/lib2to3/fixes/fix_dict.py� <listcomp>A � z%FixDict.transform.<locals>.<listcomp>c S s g | ] }|� � �qS r r r r r r r B r )�prefixZparens� �list)�syms�value� startswith�repr�in_special_contextr ZNodeZtrailerr r r r Zpowerr ) �self�node�resultsr r r r Z method_name�isiterZisviewZspecial�args�newr r r � transform6 s< ��� �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 u rdS i }|j j d ur^| j�|j j |�r^|d |u r^|rN|d jtv S |d jtjv S |sfdS | j�|j |�o�|d |u S )NFr& �func)�parent�p1�matchr! � iter_exemptr �consuming_calls�p2)r% r& r( r' r r r r$ Z s � �zFixDict.in_special_contextN) �__name__� __module__� __qualname__Z BM_compatibleZPATTERNr+ ZP1r �compile_patternr.
