from bs4 import BeautifulSoup

bs = BeautifulSoup(html)

col = bs.find('div', {
    
    'class':'col'})

col.findAll('a')
"""

现在需要找得是 text 部分含有 supplement 的 a 标签

import re
col.findAll('a',text= re.compile('Supplemental.*'))
"""
[<a class="btn btn-light btn-sm btn-spacer" href="/paper/2020/file/ec7f346604f518906d35ef0492709f78-Supplemental.pdf">Supplemental »</a>]
"""

成功！
