Python win32com 工作簿.SaveAs 'Invalid number of parameters.' 错误

Question

几个月来我一直在成功运行 python 脚本。该脚本使用 win32com 命令编辑模板 excel 电子表格，然后将编辑后的工作簿保存为新的 .xlsx 文件。

results_path = "C:\\Users\\...\\"   
results_title = results_path + input + "_Results.xlsx"

if os.path.exists(template_path):
    xl= win32com.client.gencache.EnsureDispatch("Excel.Application")
    xl.Application.DisplayAlerts = False

    xl.Workbooks.Open(Filename= template_path)
    xl.Application.Cells(2,6).Value = input
    r = 17
    for row in y_test:
        row = str(row)
        row = row[1:]
        row = row[:-1]
        xl.Application.Cells(r,2).Value = row
        r += 1
#           xl.Application.CalculateFullRebuild
#           xl.ActiveWorkbook.SaveAs(Filename = save_title)
#           time.sleep(20)
    r = 17
    for row in prediction:
        row = str(row)
        row = row[1:]
        row = row[:-1]
        xl.Application.Cells(r,3).Value = row
        r += 1
    xl.ActiveWorkbook.SaveAs(Filename = results_title)

如果不更改脚本中的任何内容，它就不再有效。有一天它停止工作了

这里是错误:

知道了!!!

有一个我必须删除的临时缓存文件夹“gen_py”。错误中文件路径引用的那个。

"C:\Users\Alex\AppData\Local\Temp\gen_py\3.5\00020813-0000-0000-C000-000000000046x0x1x9\_Workbook.py"

我不知道为什么会这样，也不知道错误最初是如何发生的，但现在一切都很好。
