Solve the following python programming problem given the following code:
def _create_intermediate_tables(docs, schema) : 
    '
    return {
        table_name: {
            row_id_number: {
                column_name: cell_data,
                ...
            },
            ...
        },
        ...
    }

    ' 
    INT = '#' 
    def lookup(doc, keys) : 
        for key in keys : 
            doc = doc [key] 
return doc 
def split_path(path) : 
        table = [] 
        column = [] 
        id = [] 
        for k in path : 
            if isinstance (k, basestring) : 
                if k : 
                    column.append (k) 
else : 
                table.extend (column) 
                table.append (INT) 
                column = [] 
                id.append (k) 
return (tuple (table), tuple (column), tuple (id)) 
schema = [schema] 
    docs = fit_to_schema (docs, schema) 
    queue = [()] 
    leaves = [] 
    while queue : 
        path = queue.pop () 
        d = lookup (docs, path) 
        if isinstance (d, dict) : 
            for key in d : 
                queue.append ((path + (key,))) 
else : 
            if isinstance (d, list) : 
                for (i, _) in enumerate (d) : 
                    queue.append ((path + (i,))) 
else : 
                if (d != list_never_was) : 
                    leaves.append ((split_path (INT), d)) 
leaves.sort () 
    tables = { 
        
} 
    for ((table_name, column_name, id), val) in leaves : 
        table = tables.setdefault (table_name, { 
            
}) 
        row = table.setdefault (id, { 
            
}) 
        row [column_name] = val 
return tables 

    
    

    Fix the buggy line: leaves.append ((split_path (INT), d))

#Here is Python code to fix the buggy line: leaves.

leaves.append ((split_path (path), d))
