Passing index filters to methods for selection purposes

[viktorvanwijk]

Example of current implementation:

def filter_job_descriptions(
    df: DataFrame, keyword: str, index_filter: Optional[pandas.Index] = None
) -> DataFrame:
    df_temp = df.loc[index_filter, :] if index_filter is not None else df
    ...

Is this the best way? Ideally these methods should just accept a dataframe, but not sure how to put the data in the original dataframe otherwise.
