学习python相关知识：参考尚学堂项目案例学习通过python获取双色球彩票信息。

网站（http://datachart.500.com/ssq/）页面信息如下：

注：需要使用到 etree包，提前进行安装

import requestsfrom  lxml import etree
url= 'http://datachart.500.com/ssq'headers={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36'}res = requests.get(url,headers=headers)res.encoding='gbk'e = etree.HTML(res.text)red_balls=[reds.xpath('./td[contains(@class,"chartBall01")]/text()' ) for reds in e.xpath('//tbody[@id="tdata"]/tr[not(contains(@class,"tdbck"))]')]blue_balls=e.xpath('//tbody[@id="tdata"]/tr[not(contains(@class,"tdbck"))]/td[contains(@class,"chartBall02")]/text()')dts=e.xpath('//tbody[@id="tdata"]/tr[not(contains(@class,"tdbck"))]/td[contains(@align,"center")]/text()')

for dt,r,b in zip(dts,red_balls,blue_balls):        print(f'{dt}期开奖号码：红球是{r} 蓝球是 {b}')

运行结果如下：
