使用字典的元组关键字的最后两个元素求和

def sum_last_two_elements(dictionary):
    total_sum = 0
    for key, value in dictionary.items():
        last_two_elements = key[-2:]  # 获取最后两个元素
        element_sum = sum(last_two_elements)  # 求和
        total_sum += element_sum  # 累加结果
    return total_sum

# 示例字典
example_dict = {('a', 'b', 'c'): 1, ('x', 'y', 'z'): 2, ('m', 'n', 'o'): 3}

# 调用函数并输出结果
result = sum_last_two_elements(example_dict)
print(result)
