这个是代码内容：

from selenium  import webdriver
import time

def serch_product():
   driver.find_element_by_xpath('//*[@id="q"]').send_keys('卫衣女')
   driver.find_element_by_xpath('//*[@id="J_TSearchForm"]/div[1]/button').click()   #搜索的 点击
   driver.find_element_by_xpath('//*[@id="login"]/div[1]/i').click()                          #电脑登录转扫码登录的点击
   time.sleep(10)
   driver.find_element_by_xpath('//*[@id="J_relative"]/div[1]/div/ul/li[2]/a').click()  #销售排序点击
   

def drop_down():
    for x in range(1,11,2):
        time.sleep(0.5)
        j=x/10
        js='document.documentElement.scrollTop=document.documentElement.scrollHeight * %f'% j
        driver.execute_script(js)               #下拉框，以便获取全部商品信息
        

def get_product():
     divs=driver.find_elements_by_xpath('//*div[@class="items"]/div[@class="item J_MouserOnverReq item-ad  "]')   #爬取商品数据
     print(divs)
     for div in divs:
         image=div.find_element_by_xpath('.//div[@class="pic"]a/img').get_attribute('stc')
         price=div.find_element_by_xpath('.//div[@id="J_Itemlist_TLink_577012675835"]').get_attribute('trace-price')+'元'
         deal=div.find_element_by_xpath('.//div[@class="deal-cnt""]').text
         info=div.find_element_by_xpath('.//div[@class="row row-2 title"]').text
         position=div.find_element_by_xpath('.//div[@class="row row-3 g-clearfix"]/div[@class="location]').text
         name=div.find_element_by_xpath('.//div[@class="shop"]/a/span[2]').text
         product={'标题':info,'价格':price,'订单量':deal,'图片':image,'店铺名字':name,'地理位置':position}
         print(product)


         
if __name__=='__main__':
    driver=webdriver.Chrome()
    driver.get('https://www.taobao.com/')
    serch_product()

代码完毕

求大大解答下：
1.这个是selenium爬虫淘宝商品，测试运行了几次搜索和登录正常，下拉框滑动（加载商品数据）正常。
但是为什么系统还是提示关于登录和按销量排序的几次点击出现这个问题飘红：DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead
2.爬虫后的分别打印解析数据，没有出现任何数据。系统报错Stacktrace:  和 Backtrace:
系统提示的错误是什么？为什么我打印不出爬取后的数据？

以下是错误内容：
