But then the beautiful soup is a world on its own:

$ python3
Python 3.4.3 (default, Nov 28 2017, 16:41:13) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from bs4 import BeautifulSoup as BS
>>> soup = BS("""<html><body><a 
>>> [a for a in soup.find_all("a") if "href" in a]
>>> [a for a in soup.find_all("a") if a.has_key("href")]
/usr/lib/python3/dist-packages/bs4/element.py:1400: UserWarning: has_key is 
deprecated. Use has_attr("href") instead.
[<a href="foo">with</a>]

At least they seem to be moving in the right direction.
