我似乎将自己与循环混淆，无法修复，我希望生成一个数据集，该数据集在我的 excel 表中向右和向下移动，但由于某种原因，每个新行都会在第一行的末尾被截断，因此我的回溯错误，试图读取上面的空单元格。我希望能有一些新鲜的眼光，因为我后来的代码依赖于这个正确的输出，希望它能够解决全球经济衰退，或者不是，但会让我成为一个快乐的人。:)

我的追溯是：

Traceback (most recent call last):

EC_D = ECDD1 - (ECDD2*FC_Error)
TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'

I totally don't get what are you trying to compute, but here's the cause of the mentioned exception.

First of all, in your first for loop, in the excel file you take a row (row #1), and fill the columns in that row from column #1 to column #52 (indexing starts from 0):

Later, in the second for loop, when you read the values, you increase the global counter so when the exception is thrown, you are trying to read the values for the 53th week.

Solution: instead of 

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

you could 

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

You actually created the DiffWeek variable but forgot to use it.
