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)NameCallDot) fixer_utiliterc@s@eZdZdZdZddZdZejeZ dZ eje Z ddZ d S) FixDictTa power< head=any+ trailer< '.' method=('keys'|'items'|'values'| 'iterkeys'|'iteritems'|'itervalues'| 'viewkeys'|'viewitems'|'viewvalues') > parens=trailer< '(' ')' > tail=any* > c Cs|d}|dd}|d}|j}|j}|jd}|jd} |sD| rP|dd}|dksdtt|d d |D}d d |D}| o|j||} |tj|jt t ||j dg|dj g} tj|j | } | p| sd| _ tt |rdnd| g} |rtj|j | g|} |j | _ | S)Nheadmethodtailr ZviewkeysitemsvaluescSsg|] }|jqS)clone).0nrr /usr/lib64/python3.6/fix_dict.py Asz%FixDict.transform..cSsg|] }|jqSr)r)rrrrrrBs)prefixZparenslist)rrr)symsvalue startswithAssertionErrorreprin_special_contextrZNodeZtrailerrrrrZpowerr) selfnoderesultsr r rrZ method_nameisiterZisviewZspecialargsnewrrr transform6s4      zFixDict.transformz3power< func=NAME trailer< '(' node=any ')' > any* >zmfor_stmt< 'for' any 'in' node=any ':' any* > | comp_for< 'for' any 'in' node=any any* > cCs|jdkrdSi}|jjdk r^|jj|jj|r^|d|kr^|rN|djtkS|djtjkS|sfdS|jj|j|o|d|kS)NFr#func)parentp1matchr iter_exemptrconsuming_callsp2)r"r#r%r$rrrr!Zs   zFixDict.in_special_contextN) __name__ __module__ __qualname__Z BM_compatibleZPATTERNr(ZP1rZcompile_patternr+ZP2r/r!rrrrr )s   r N) __doc__rrrrrrrrr.r-ZBaseFixr rrrrs
