因為筆者經常投彩票，於是做了一個玩，初版本只是爬取，效果如下：

程式碼如下：

import requests
from requests.exceptions import RequestException
from lxml import etree
count = 0
def get_page(url):
    try:
        headers = {
            'user-agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Mobile Safari/537.36',
            'accept-language': 'zh-CN,zh;q=0.9',
            'cache-control': 'max-age=0',
            'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8'
        }
        response = requests.get(url=url,headers=headers)
        # 更改編碼方式，否則會出現亂碼的情況
        response.encoding = "utf-8"
        if response.status_code == 200:
            return response.text
        return None
    except RequestException:
        return None
def parse_page(html):
    try:
        global count
        count+=1
        res = etree.HTML(html)
        red = res.xpath('//*[@class="smallRedball"]//text()')
        blue = res.xpath('//*[@class="smallBlueball"]//text()')
        print(red+blue)
    except Exception as e:
        pass
def main(num):
    url = 'http://caipiao.163.com/t/award/dlt/{}.html'.format(str(num))
    html = get_page(url)
    parse_page(html)
if __name__ == '__main__':
    for num in range(17001,17154):
        main(num)
    for num in range(18001, 18140):
        main(num)
    print("大樂透爬取結束...")
    print("爬取的數目為："+str(count))
