Calls to .has_key() methods are expressed in terms of the 'in' operator: d.has_key(k) -> k in d CAVEATS: 1) While the primary target of this fixer is dict.has_key(), the fixer will change any has_key() method call, regardless of its class. 2) Cases like this will not be converted: m = d.has_key if m(k): ... Only *calls* to has_key() are converted. While it is possible to convert the above to something like m = d.__contains__ if m(k): ... this is currently not done. é)Úpytree)Útoken)Ú fixer_base)ÚNameÚ parenthesizec@s(eZdZdZdZdd„ZdS)Ú FixHasKeyTa• anchor=power< before=any+ trailer< '.'
