+        Codes in MultiIndex refers to Integer codes for each level of 
+        MultiIndex.
+
+        The codes attribute represents the integer codes that are used
+        internally to represent each label in the corresponding level of the
+        MultiIndex. These codes facilitate efficient storage and retrieval of
+        hierarchical data.
+
+        Each element in the list corresponds to a level in the MultiIndex,
+        and the arrays within the list contain the integer codes for the
+        labels at that level.
+        
+        Examples
+        -------
+        >>> df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
+        >>> df.set_index(['A', 'B'], inplace=True)
+        >>> df.index.codes
+        [array([0, 1, 2]), array([0, 1, 2])]

+        >>> levels = [[2, 3, 1], ['Gold', 'Silver', 'Bronze']]
+        >>> codes = [[2, 0, 1], [0, 1, 2]]
