Hi! Any idea why this patch is needed? Looks to me like it suppresses some exception? But I don't know much python ...

The patch was supplied by the author of the port.
Without it, the byte compiler fails (poudriere-testport output without the patch):

byte-compiling /wrkdirs/usr/ports/www/py-readability-lxml/work-py39/stage/usr/local/lib/python3.9/site-packages/readability/compat/two.py to two.cpython-39.pyc
  File "/usr/local/lib/python3.9/site-packages/readability/compat/two.py", line 6
    raise exc_type(*args, **kwargs), None, traceback
                                   ^
SyntaxError: invalid syntax

I did not further investigate into upstream tho.

Nevermind, turns out this code is for python 2.x only, so will never be executed anyways.

I would recommend adding a comment to the patch, something like disable some python-2.x code that's invalid syntax in python 3.

Leave comment in potentially obscure patch
