It's a tedious way to build a new list, and you are throwing it away in the next line anyway, as adding first_list + second_list creates a new list containing the items of both. So: data = shlex.split(ln) fld = data + [""] * (5 - len(data)) # the OP wants strings -- https://mail.python.org/mailman/listinfo/python-list

What's the neatest way of setting the fourth and fifth entries to an empty string if they don't (yet) exist?

(In which case that's something not mentioned in > the specification.) if only 5 entries are required than simply prune off the extra using a slice as I suggested yesterday -- DalNet is like the special olympics of IRC.

So apparently I've been banned from this list
I've been unexpectedly in hospital for the past two weeks, without internet or email. Just before my unexpected hospital stay, I was apparently banned (without warning) by Ethan Furman in what seems to me to be an act of retaliation for my protest against his overzealous and hostile tone-policing against a newcomer to the list, Reto Brunner: https://mail.python.org/pipermail/python-list/2018-September/737020.html (I did make one mistake in that post: I claimed that I hadn't said anything at the time on Ethan's last round of bans. That was incorrect, I actually did make an objection at the time.) Since I'm still catching up on emails, I have just come across Ethan's notice to me (copied below). Notwithstanding Ethan's comment about having posted the suspension notice on the list, I see no sign that he actually did so. At the risk of further retaliation from the moderators, I am ignoring the ban in this instance for the purposes of transparency and openness. (I don't know if this will show up on the mailing list or the newsgroup.) Since I believe this ban is illegitimate, I intend to challenge it if possible. In the meantime, I may not reply on-list to any responses. Subject: Fwd: Temporary Suspension To: From: Ethan Furman Date: Tue, 11 Sep 2018 11:22:40 -0700 In-Reply-To: Steven, you've probably already seen this on Python List, but I forgot to email it directly to you.

To me it means a place that python users can go to ask questions, get answers, offer advice, and all without sarcasm, name-calling, and deliberate mis-understandings.

Is it possible that the message about the suspension was sent only to -owner and not to the list? Was it meant to be sent to the whole list?
