If you have working code that you're looking to have peer-reviewed, you should ask on Code Review instead - it was created just for that purpose. Make sure you read and understand their site guidelines before posting there. This site is for questions about specific problems you're having with code or use of a programmer's tool. — Ken White 14 secs ago

This is a question more suited to Code Review. That said, the latter is better to write tests for and the like. — t56k 19 secs ago

Q: Remove Duplicate Lines Without Sorting or Removing Empty Lines

bluerayI am using the following oneliner to remove duplicate lines without sorting or removing empty lines perl -ne 'if ( /^\s*$/ ) { print } else { print if ! $x{$_}++}' However, this code seems bulky, specially the $x{$_}++ part. Is there any way I can make this code more readable and understandable.

Q: Python type Optional[type] vs Union[type, None] vs type | None

Daniel MorellWith Python 3.10 there is an additional way to explicitly define a possible None type. I can think of three ways to do it currently. My question has two parts... Is there any inherent value of one over the other? Would you recommend using them to indicate different things? A. Optional[type] fro...

@CaptainObvious I closed user's first question for being too hypothetical - despite having some concrete code but it seemed to focus on generic best practices, and now it is RBA; the code in this question seems to not have holes but is quite brief
 
@SᴀᴍOnᴇᴌᴀ That's not what a GBP is.
"What is the best way to write comments" not "Is the way I've written my comments adhering to best practices".
 
@Peilonrayz are you referring to the new question and/or the deleted one?

@BCdotWEB @TobySpeight Do we really need to chase away new users?

I think you can invite to the 2nd through the chat profile or comment on main somewhere.

Q: Is it considered bad code/style to use built-in libraries to solve a programming problems?

My question is in the real-world and in programming interviews is it considered bad to use built-in libraries? For example (using it...

Welcome to stack overflow! If you have code that works but you want to improve the efficiency, the the Code Review stack site is the site for you. "Please code this for me" is otherwise off-topic for stack overflow, where we ask for specific questions with specific answers, for which you can provide a minimal reproducible exampleG.

@pacmaninbw Asking for an edit is "chasing away"? ? I would have edited it myself, but I couldn't work out what the code is for - definitely needs help from the OP.
 
@TobySpeight I agree that when it was first posted it had major problems, but there was more code added with an explanation.
 
@TobySpeight tbf with the amount of votes and comments (saying I'm wrong) from different people on the question, if I were the OP I would feel like I'm being dogged on
 
I don't know who voted to close, but it wasn't that bad to require a VTC IMHO.
 
@pacmaninbw Sadly not enough explanation for me to be able to summarise with a new title - that's why I asked the OP to do that.
 
@TobySpeight I think an experienced user (1800+) called you pedantic yesterday. I'm just saying it might be better to edit the title.
 
8:30 PM
So the only purpose of using [ref] is to force function calls to use the actual parameter name to ease you code reviews? — Dennis 11 secs ago
 
At least some of the time.
 
@pacmaninbw Yes, being pedantic is important in a reviewer; not sure how that's relevant to this question. As I say, I went to edit the title, but found I couldn't (it seems to be for some kind of game, but no description of the rules or anything).
 
huh, what happened?
@TobySpeight OK, true.

Q: Database schema for discussion forum scraping

@TobySpeight when I see a comment I agree with it, 1 comment should be good enough.
I do appreciate your attention to detail.
 
8:40 PM
@pacmaninbw I assumed the comment with a datestamp before the edit was referring to the original title; I was explaining that the edited title wasn't an improvement. Was that the wrong thing to do?
 
@TobySpeight I think at that point it might have been better to ask is this a game, and if so what game?
 
@pacmaninbw Yes, that might have been a useful question to ask.
 
OK. Thanks for listening.
