keep_object_prefixes

keep_object_prefixes(triples: Iterable[TripleType], prefixes: str | Iterable[str], *, progress: bool = False) → Iterable[TripleType][source]

Keep triples whose objects’ prefixes are in the given prefixes.

Parameters:

  • triples – An iterable of triples

  • prefixes – A set of prefixes to use for filtering the triples

  • progress – Should a progress bar be shown?

Returns:

A sub-iterable of triples whose objects’ prefixes are in the given prefixes
