modin.pandas.DataFrame.idxmin¶

DataFrame.idxmin(axis=0, skipna=True, numeric_only=False)[source]¶

Return index of first occurrence of minimum over requested axis.

Parameters:

  • axis ({0 or 1}, default 0) – The axis to use. 0 for row-wise, 1 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.

Return type:

Series if DataFrame input, Index if Series input

Examples

>>> 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
