这个是淘宝爬虫的代码内容：
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几次点击出现这个飘红问题：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意思？为什么我打印不出爬取后的数据？
以下是错误内容：
