Méthode pandas.MultiIndex.get_slice_bound

Signature de la méthode get_slice_bound

def get_slice_bound(self, label: Union[Hashable, Sequence[Hashable]], side: str, kind: str) -> int 

Description

get_slice_bound.__doc__

        For an ordered MultiIndex, compute slice bound
        that corresponds to given label.

        Returns leftmost (one-past-the-rightmost if `side=='right') position
        of given label.

        Parameters
        ----------
        label : object or tuple of objects
        side : {'left', 'right'}
        kind : {'loc', 'getitem'}

        Returns
        -------
        int
            Index of label.

        Notes
        -----
        This method only works if level 0 index of the MultiIndex is lexsorted.

        Examples
        --------
        >>> mi = pd.MultiIndex.from_arrays([list('abbc'), list('gefd')])

        Get the locations from the leftmost 'b' in the first level
        until the end of the multiindex:

        >>> mi.get_slice_bound('b', side="left", kind="loc")
        1

        Like above, but if you get the locations from the rightmost
        'b' in the first level and 'f' in the second level:

        >>> mi.get_slice_bound(('b','f'), side="right", kind="loc")
        3
