cudf.Index.argsort

Index.argsort(axis=0, kind='quicksort', order=None, ascending=True, na_position='last') → ndarray

Return the integer indices that would sort the index.

Parameters:

axis{0 or “index”}

Has no effect but is accepted for compatibility with numpy.

kind{‘mergesort’, ‘quicksort’, ‘heapsort’, ‘stable’}, default ‘quicksort’

Choice of sorting algorithm. See numpy.sort() for more information. ‘mergesort’ and ‘stable’ are the only stable algorithms. Only quicksort is supported in cuDF.

orderNone

Has no effect but is accepted for compatibility with numpy.

ascendingbool or list of bool, default True

If True, sort values in ascending order, otherwise descending.

na_position{‘first’ or ‘last’}, default ‘last’

Argument ‘first’ puts NaNs at the beginning, ‘last’ puts NaNs at the end.

Returns:

cupy.ndarray: The indices sorted based on input.
