Examples
idx = pd.Index([10, 100, 1, 1000]) idx Int64Index([10, 100, 1, 1000], dtype='int64')
Sort values in ascending order (default behavior).
idx.sort_values() Int64Index([1, 10, 100, 1000], dtype='int64')
Sort values in descending order, and also get the indices idx was sorted by.
idx.sort_values(ascending=False, return_indexer=True) (Int64Index([1000, 100, 10, 1], dtype='int64'), array([3, 1, 0, 2]))
