要下载任何在其文件名中包含pdf的qp_2，可以使用下一个示例：
import requests
from bs4 import BeautifulSoup
url = "https://papers.gceguide.com/A%20Levels/Physics%20(9702)/2015/"
soup = BeautifulSoup(requests.get(url).content, "html.parser")
for n in soup.select('a.name[href*="qp_2"]'):
print("Downloading", n.text)
with open(n.text, "wb") as f_out:
r = requests.get(url + n.text)
f_out.write(r.content)打印和下载文件：
