Question

我似乎把自己弄得一团糟无法修复，我期待生成一个在我的Excel工作表中向右和向下移动的数据集，但由于某种原因，每个新行都会在第一行的末尾被截断，因此我的追溯错误，whcih试图读取上面的空单元格。我会欣赏一些新鲜的眼睛，因为我后来的代码依赖于这个正确的输出，并希望它能解决全球经济衰退，或者不会，但会让我成为一个快乐的人。：）

我的追溯是：

Traceback (most recent call last):
File "C:\Python27\Darren Learning Samples\codetesting2.py", line 85, in <module>
EC_D = ECDD1 - (ECDD2*FC_Error)
TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'

Answer 1

我完全没有得到你想要计算的东西，但这是上述异常的原因。

首先，在您的第一个for循环中，在excel文件中取一行（第1行），并填充该行中从第1列到第52列的列（索引从0）：

稍后，在第二个for循环中，当您读取值时，会增加全局计数器，因此在抛出异常时，您将尝试读取第53周的值。

解决方案：而不是

        ECDD1 = sheet1.cell(row=Prev_Week, column=PlanWeek).value
        ECDD2 = sheet1.cell(row=Prev_Week, column=PlanWeek).value
        EC_demand = ECDD1 - (ECDD2*FC_Error)

你可以

        ECDD1 = sheet1.cell(row=Prev_Week, column=DiffWeek).value
        ECDD2 = sheet1.cell(row=Prev_Week, column=DiffWeek).value
        EC_demand = ECDD1 - (ECDD2*FC_Error)

您实际创建了DiffWeek变量但忘记使用它。
