pandas.Index.argmin#

Index.argmin(axis=None, skipna=True, *args, **kwargs)[source]#

Return int position of the smallest value in the Series.

If the minimum is achieved in multiple locations, the first row position is returned.

Parameters

axis{None}: Unused. Parameter needed for compatibility with DataFrame.
skipnabool, default True: Exclude NA/null values when showing the result.
*args, **kwargs: Additional arguments and keywords for compatibility with NumPy.

Returns

int: Row position of the minimum value.

Series.argmin: Return position of the minimum value.
Series.argmax: Return position of the maximum value.
numpy.ndarray.argmin: Equivalent method for numpy arrays.
Series.idxmax: Return index label of the maximum values.
Series.idxmin: Return index label of the minimum values.

Examples

Consider dataset containing cereal calories

>>> s = pd.Series({'Corn Flakes': 100.0, 'Almond Delight': 110.0,
...                'Cinnamon Toast Crunch': 120.0, 'Cocoa Puff': 110.0})
>>> s
Corn Flakes              100.0
Almond Delight           110.0
Cinnamon Toast Crunch    120.0
Cocoa Puff               110.0
dtype: float64

>>> s.argmax()
2
>>> s.argmin()
0

The maximum cereal calories is the third element and the minimum cereal calories is the first element, since series is zero-indexed.
