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

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

Parameters :

axis : int (can only be zero)

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

Choice of sorting algorithm. See np.sort for more information. ‘mergesort’ is the only stable algorithm

order : ignored

Returns :

argsorted : Series, with -1 indicated where nan values are present
