[Tutor] Unable to retreive the stock code

[Crusier]

Dear All,

I am currently trying to download the stock code. I am using Python
3.4 and the code is as follows:

from bs4 import BeautifulSoup
import requests
import re

url = 'https://www.hkex.com.hk/eng/market/sec_tradinfo/stockcode/eisdeqty.htm'

def web_scraper(url):
    response = requests.get(url)
    html = response.content
    soup = BeautifulSoup(html,"html.parser")
    for link in soup.find_all("a"):
        stock_code = re.search('/d/d/d/d/d', "00001" )
        print(stock_code, '', link.text)
        print(link.text)

web_scraper(url)

I am trying to retrieve the stock code from here:
<td class="verd_black12" width="18%">00001</td>

or from a href.

Please kindly inform which library I should use.

Thanks
Henry
