我自己寫的一段程式碼：

#開啟excel檔案讀取資料
data = xlrd.open_workbook('source_aa.xls',formatting_info=True)

#通過索引順序獲取:但是通過sheet_by_index獲取的sheet沒有write()方法
table
 
 = data.sheet_by_index(0)

#寫入的另外一個檔案
workbook = xlwt.Workbook(encoding='utf-8')
data_sheet = workbook.add_sheet('demo1')



for rowIndex in range(0,table.nrows):
    for colIndex in range(0,table.ncols):
        if '1' in str(table.cell(rowIndex, 0).value):
            print('.....')
            break
        data_sheet.write(rowIndex, colIndex, table
 
.cell(rowIndex, colIndex).value)


workbook.save('demo7.xls')
