keep_triples_by_hash

keep_triples_by_hash(triples: Iterable[TripleType], converter: Converter, triple_hashes: str | Iterable[str], *, progress: bool = False) → Iterable[TripleType][source]

Keep triples whose triple hash (under the given converter) is in the given collection.

Parameters:

  • triples – An iterable of triples

  • converter – A converter

  • triple_hashes – A hash or hashs to check triples for

  • progress – Should a progress bar be shown?

Returns:

A sub-iterable of triples whose triple hash under the given constructor appears in the given collection
