Python怎么实现拆分表格中的数据

怎么将前面这张表的数据通过/拆分为下面这张表的数据。用到的包xlrd和xlwt

import xlrd
import xlwt


def readFromExcelByXlrd(filename, toSaveFilename, sheetName='Sheet1'):
    try:
        book1 = xlrd.open_workbook(filename)
        sheet1 = book1.sheet_by_name(sheetName)
        nrows = sheet1.nrows
        # ncols = sheet1.ncols

        book2 = xlwt.Workbook(encoding='utf-8')
        sheet2 = book2.add_sheet(sheetName, True)

        r = 0
        for i in range(nrows):
            row = sheet1.row_values(i)
            params = row[1].split("/")
            for time in range(len(params)):
                sheet2.write(r, 0, row[0])
                sheet2.write(r, 1, params[time])
                sheet2.write(r, 2, row[2])
                r += 1
        book2.save(toSaveFilename)
    except Exception as e:
        print(str(e))


if __name__ == '__main__':
    filename = r'C:\Users\Lenovo\Desktop\1.xlsx'
    filename1 = r'C:\Users\Lenovo\Desktop\2.xlsx'
    readFromExcelByXlrd(filename, filename1)

这不就是字符串分割？按行读取，split('/')分割第1列数据，然后第0列和第2列不变，分割多少份就生成多少行数据，分割完了再写入新文件
