Solve the following python programming problem given the following code:
def claim_e2e_one_time_keys(self, query_list) : 
    'Take a list of one time keys out of the database' 
    def _claim_e2e_one_time_keys(txn) : 
        sql = 'SELECT key_id, key_json FROM e2e_one_time_keys_json WHERE user_id = ? AND device_id = ? AND algorithm = ? LIMIT 1' 
        result = { 
            
} 
        delete = [] 
        for (user_id, device_id, algorithm) in query_list : 
            user_result = result.setdefault (user_id, { 
                
}) 
            device_result = user_result.setdefault (device_id, { 
                
}) 
            txn.execute (sql, (user_id, device_id, algorithm)) 
            for (key_id, key_json) in txn.fetchall () : 
                device_result [((algorithm + ':') + key_id)] = key_json 
                delete.append ((user_id, device_id, algorithm, key_id)) 
sql = 'DELETE FROM e2e_one_time_keys_json WHERE user_id = ? AND device_id = ? AND algorithm = ? AND key_id = ?' 
        for (user_id, device_id, algorithm, key_id) in delete : 
            txn.execute (sql, (user_id, device_id, algorithm, key_id)) 
return result 
return self.runInteraction ('claim_e2e_one_time_keys', query_list) 

    
    

    Fix the buggy line: return self.runInteraction ('claim_e2e_one_time_keys', query_list)

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