爬取古诗文网站

重点是练习正则表达式的使用

链接变化

url_base = 'https://www.gushiwen.cn/default_{}.aspx'
for i in range(1, 2):
    print('正在爬取第{}页：'.format(i))
    url = url_base.format(i)

要求1爬取李白的诗前几页

2爬取推荐页面前几页

换个链接均可以实现

古诗题目 

titles = re.findall(r'<b>(.*?)</b>', text, flags=re.DOTALL)  #  flags=re.DOTALL 来对这些 tab, new line 不敏感.

作者

authors=re.findall(r'<p class="source">.*?<a.*?>(.*?)</a>', text, flags=re.DOTALL)
