This is functionally equivalent to iterating over the items in the forward mapping and inverting each one on the fly, but this provides a more efficient implementation: Assuming the already-inverted items are stored in :attr:`inverse`, just return an iterator over them directly. Providing this default implementation enables external functions, particularly :func:`~bidict.inverted`, to use this optimized implementation when available, instead of having to invert on the fly. *See also* :func:`bidict.inverted` )iterritemsr s r __inverted__z!BidirectionalMapping.__inverted__5sDLL&&())rN)returnzBidirectionalMapping[VT, KT])rzt.Iterator[tuple[VT, KT]]) __name__ __module__ __qualname____doc__ __slots__propertyrrrr rrr r s-I  " "*rr ceZdZdZdZy)MutableBidirectionalMappingzr&s^E")*199RV,)*X"6r2v">@P@PQSUWQW@Xr
