pandas.Series.argsort

Series.argsort(axis=0, kind='quicksort', order=None)[source]

Return the integer indices that would sort the Series values.

Override ndarray.argsort. Argsorts the value, omitting NA/null values, and places the result in the same locations as the non-NA values.

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.
order:None: Has no effect but is accepted for compatibility with numpy.

Returns

Series[np.intp]: Positions of values within the sort order with -1 indicating nan values.
