我有一个包含项目和说明的Excel文件,我试图比较相似性的描述,如果它们相似,则将它们放在一个新的Excel文件中。这些项目也有目录#' s我比较它们以确定它们是否彼此不相同,并且它们来自同一供应商(buy_line)也将它们放在新的Excel文件。当我运行文件时,它需要太长时间,在我让它运行后,我回来了,Spyder关闭,没有新文件。所以这是一个2部分问题,有没有办法让代码更快?为什么没有创建文件?先感谢您。我的代码在

Create_ExcelFile()功能存在一些问题。首先是没有工作簿save()方法。此外,您还没有递增row2,因此第二个write()将始终写入第一行,并覆盖其他任何内容。但是,最重要的是,close()方法处于错误的级别,因此您过早关闭文件。这样的事情应该有效:

def Create_ExcelFile():
    NewWorkbook = xlsxwriter.Workbook('Sim_Desc.xlsx')
    worksheet = NewWorkbook.add_worksheet()

    row1 = 0
    row2 = 0

    for items in similar_desc_item:
        worksheet.write(row1,0,items)
        row1 += 1

    for catalognumb in diff_catalog_samebuyline:
        worksheet.write(row2,3,catalognumb)
        # Fix the row2 increment!!

    NewWorkbook.close()
