Python/PSSE错误：TypeError:需要整数

Question

在尝试将信息加载到PSSE时，我在代码末尾收到一个错误。我的目标是，一旦所有的数据按照我想要的方式组织起来，下一步就是使用这些有组织的数据并将其导入PSSE。在这之前的一切都是可行的，但是一旦我使用了psseapi，就什么都不起作用了。我得到这个错误： pspy.bsys公司（1,0，[0.0,0.0]，0，[]，1，[总线]，0，[]，0，[]） 文件”\pspy.py“，第46020行，bsys TypeError:需要整数。在

Answer 1

for bus in busses_in_year[location]:
    print(bus)

这个印什么？根据前面的代码，我认为bus实际上是tuple：

^{pr2}$

当您用[bus]调用bsys时，它正在循环使用busses_in_year[location]之后的最后一个值bus。函数bsys需要一个整数，但您给它的却是完整的tuple。在

我不确定如何修复您的代码，因为在一年中只坐最后一班车可能没有意义，所以您可能需要先修复它。在

但是，如果您想正确地解压缩tuple(bus, change, isload)，可以执行以下操作：

for bus, change, isload in busses_in_year[location]:
    print(bus)
