missionbio.mosaic.utils.get_indexes

missionbio.mosaic.utils.get_indexes(from_list: Sequence, find_list: Sequence, order_using_find_list: bool = False) → numpy.ndarray

Find the intersection of arrays.

Parameters

from_listlist-like

The list for which indexes are to be found.

find_listlist-like

The list containing values which are to be matched in from_list.

order_using_find_listbool

If True, then the order in find-list is maintained otherwise the order in the from-list is maintained

Returns

indexes

Returns the indexes in from_list for values that are found in find_list.

Notes

get_indexes is much faster than np.where(np.isin(from_list, find_list)), but it uses more memory since it duplicates the data.
