            if len(row[j]) > 0:
                sheet.cell(row=(i +2), column=(j+1), value=row[j][0])
    book.save(path)  # 保存

#主函数

    print("开始爬取......")
    #爬取8-12万汽车地址
    baseurl = 'https://car.autohome.com.cn/price/list-8_12-0-0-0-0-0-0-0-0-0-0-0-0-0-0-'
    datalist = getData(baseurl)
    savapath='cars.xls'
    saveData(datalist,savapath)

main()
print("爬取完成")

展示成果！！
