# pandas.Index.argmin

Index.argmin(axis=None, skipna=True, *args, **kwargs)

  Return int position of the smallest value in the Index.

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

  Parameters:
    axis None

      Unused. Parameter needed for compatibility with DataFrame.

    skipna bool, default True

      Exclude NA/null values. If the entire Series is NA, or if `skipna=False` and there is an NA value, this method will raise a `ValueError`.

    *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.idxmin`

    Return index label of the minimum values.

  `Series.idxmax`

    Return index label of the maximum values.

  Examples

  Consider dataset containing cereal calories

      >>> idx = pd.Index([100.0, 110.0, 120.0, 110.0])
      >>> idx
      Index([100.0, 110.0, 120.0, 110.0], dtype='float64')

      >>> idx.argmax()
      np.int64(2)
      >>> idx.argmin()
      np.int64(0)

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