get_df_unique_prefixes

get_df_unique_prefixes(df: DataframeOrSeries, *, column: str | int | None = None, validate: bool = False, converter: Converter | None = None) → set[str][source]

Get unique prefixes.

Parameters:

df – A dataframe or series. If a dataframe is given, the column must not be none.
column – The column to check, if a dataframe was passed. If a series was passed, this can be left as none.
validate – Should the prefixes be validated against the converter?
converter – A converter for validating CURIEs

Returns:

A set of prefixes appearing in CURIEs in the given column
