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. i ( t pytree( t token( t fixer_base( t Namet parenthesizet FixHasKeyc B s e Z e Z d Z d � Z RS( s� anchor=power< before=any+ trailer< '.'
