如何解决此 python 程序中的错误？
How solve error in this python program?
我是 python 的初学者，我有很多很多关于 it.I 试图创建程序但我没有得到结果的问题 exactly.Only 计算很少，剩下的印刷品。

缩进是 proper.The 错误是 "totrate is referenced before assignment" 我在所有允许全局变量的地方都给了它，但仍然没有 come.And 当我得到结果时，finrate 没有得到printed.instead None 或 0 comes.please 让我知道 mistakes.Is 有什么我应该导入的吗？抱歉 trouble.Its 的 class 演示文稿.
感谢您的努力。
totrate=totrate+frate+trate
您已将 totrate 初始化为列表。您不能以这种方式与列表对象进行交互。我相信您想使用 int 类型而不是列表。例如 totrate = 1000
另请注意，这些不是全局变量而是局部变量，因为它们在函数的范围内。
