DataFrame.idxmin(axis: Axis = 0, skipna: bool = True, numeric_only: bool = False) Series[source]#

Return index of first occurrence of minimum over requested axis.

NA/null values are excluded.

  • axis ({0 or 'index', 1 or 'columns'}, default 0) – The axis to use. 0 or ‘index’ for row-wise, 1 or ‘columns’ for column-wise.

  • skipna (bool, default True) – Exclude NA/null values. If an entire row/column is NA, the result will be NA.

  • numeric_only (bool, default False) –

    Include only float, int or boolean data.

    New in version 1.5.0(pandas).


Indexes of minima along the specified axis.

Return type




  • If the row/column is empty

Return index of the minimum element.


This method is the DataFrame version of ndarray.argmin.


Consider a dataset containing food consumption in Argentina.

>>> df = pd.DataFrame({'consumption': [10.51, 103.11, 55.48],  
...                     'co2_emissions': [37.2, 19.66, 1712]},
...                   index=['Pork', 'Wheat Products', 'Beef'])
>>> df  
                consumption  co2_emissions
Pork                  10.51         37.20
Wheat Products       103.11         19.66
Beef                  55.48       1712.00

By default, it returns the index for the minimum value in each column.

>>> df.idxmin()  
consumption                Pork
co2_emissions    Wheat Products
dtype: object

To return the index for the minimum value in each row, use axis="columns".

>>> df.idxmin(axis="columns")  
Pork                consumption
Wheat Products    co2_emissions
Beef                consumption
dtype: object
