我自己写的一段代码：

#打开excel文件读取数据
data = xlrd.open_workbook("source_aa.xls",formatting_info=True)

#通过索引顺序获取:但是通过sheet_by_index获取的sheet没有write()方法
table = data.sheet_by_index(0)

#写入的另外一个文件
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")
