# 需求：拷贝excel中的内容到另外一个excel中

flile_name = "7月下旬入库表.xlsx"

将文件列表写入excel中

import os
import xlwt

file_dir = "d:/"
listdirs = os.listdir(file_dir)
workbook = xlwt.Workbook()
sheet0 = workbook.add_sheet("newtest")
n = 0
for i in listdirs:
    sheet0.write(n,0,i)
    n += 1
workbook.save("listdirs.xls")
