def idxmin(self, axis=None, out=None, skipna=True):
        """
        Index of first occurrence of minimum of values.

        Parameters
        ----------
        skipna : boolean, default True
            Exclude NA/null values

        Returns
        -------
        idxmin : Index of minimum of values

        Notes
        -----
        This method is the Series version of ``ndarray.argmin``.

def idxmin(self, axis=None, skipna=True, *args, **kwargs):
        """
        Index *label* of the first occurrence of minimum of values.

        Parameters
        ----------
        skipna : boolean, default True
            Exclude NA/null values. If the entire Series is NA, the result
            will be NA.

        Raises
        ------
        ValueError
            * If the Series is empty

        Returns
        -------
        idxmin : Index of minimum of values

        Notes
        -----
        This method is the Series version of ``ndarray.argmin``. This method
        returns the label of the minimum, while ``ndarray.argmin`` returns
        the position. To get the position, use ``series.values.argmin()``.
