>>> idx = ps.Index(['a', 'b', 'c'])
>>> idx
Index(['a', 'b', 'c'], dtype='object')
>>> idx.repeat(2)
Index(['a', 'b', 'c', 'a', 'b', 'c'], dtype='object')

For MultiIndex,

>>> midx = ps.MultiIndex.from_tuples([('x', 'a'), ('x', 'b'), ('y', 'c')])
>>> midx  
MultiIndex([('x', 'a'),
            ('x', 'b'),
            ('y', 'c')],
           )
>>> midx.repeat(2)  
MultiIndex([('x', 'a'),
            ('x', 'b'),
            ('y', 'c'),
            ('x', 'a'),
            ('x', 'b'),
            ('y', 'c')],
           )
>>> midx.repeat(0)  
MultiIndex([], )
