mini challenge!!! can someone make this python3 program into one line? (without using a semicolon). Or is two lines the limit?-
val = int(100 * float(input("O hai! How much change is owed? ")))
print(val//25 + (val%25)//10 + (val%25%10)//5 + val%25%10%5)

Anonymous

@AshwinGupta Pretty simple using two nested lambdas

Ashwin Gupta

oh good thought

btw the context of this is me being extra with CS-P homework.

Anonymous

Actually just one lambda is sufficient

Ashwin Gupta

how would you do that?

with one

Anonymous

(lambda val:print(val//25 + (val%25)//10 + (val%25%10)//5 + val%25%10%5))(int(100 * float(input("O hai! How much change is owed? "))))

Ashwin Gupta

04:27

ohohohoh intresting

but I still have to call the lambda

Anonymous

That calls the lambda in one line, though

Ashwin Gupta

clever

i love it

Bubbler

04:40

[print(val//25 + (val%25)//10 + (val%25%10)//5 + val%25%10%5) for val in [int(100 * float(input("O hai! How much change is owed? ")))]]

This will also work

Ashwin Gupta

hoooh also nice @Bubbler

Hmm, my sister in law walks around in our house wearing only a thong and a bra. (Not in the living room, but between a guest bedroom and guest bathroom, and they are not in adjacent rooms).

Adám

@StewieGriffin And it bothers you?

Stewie Griffin

I didn't take a photo, but I can inform you that our ceiling and floor look really nice!

@Adam, Well, yes... I have to look away, so I'm walking around in my own house staring at the floor.

Adám

@StewieGriffin Are you afraid you'll feel aroused if you look at her? (A noble fear, imho)

Stewie Griffin

Nope... but it's awkward if she looks at me at the same time in accidentally looking in get direction.

Adám

@StewieGriffin Why do you think it is awkward?

Stewie Griffin

Because it's impossible to tell if I briefly glanced over at her, or if I have been staring at her 15 seconds.

Adám

@StewieGriffin Obviously you think there is something wrong with you having stared at her for 15 seconds. But what kind of wrong? Did you do something wrong towards her?

Stewie Griffin

08:47

She obviously doesn't care much though...

Adám

@StewieGriffin Exactly, my point. Otherwise she would make sure to cover herself more. In fact, maybe she likes being looked at.

Q: Let's golf a BIBABOBU decoder

While I was traveling in the future, I noticed a funny game among kids circa 2275. When they don't want their grand-grand-grand-grand-grand parents to understand what they're saying, they use the BIBABOBU speak. Obviously, I couldn't understand anything either with my pre-cyborg era brain and I f...

Stewie Griffin

I'm sure she thinks I won't look or mind, since I'm married to her sister. She's right, and that's why I don't want her to see me looking at her (which could happen unless I'm staring at the floor). So I'm staring at the floor.

Adám

@StewieGriffin She's right about what? That you won't look? You take care to look away, so you do mind, right? Personally, I'd be more worried that my wife would dislike my staring at her unclad sister, especially if the sister is younger or (perceived to be) better-looking.

@Mego Can you move from here to this message (except NMP's) into The Awkward Silence?

Stewie Griffin

...or just delete it all together.

Adám

09:02

@StewieGriffin No, why? I, for one, appreciate that you seek advice about such touchy subjects.

Fatalize

@StewieGriffin This could have the opposite effect if you stare at the floor too much: she could see that as "he finds me attractive and tries really hard to not show it" instead of "he doesn't give a damn about me" if you act as normal

Adám

@StewieGriffin If I was in your situation, I would tell my wife about the issue, and ask if all three of us could sit down for a talk about it. Then I would try let my sister-in-law know that I acknowledge and appreciate that she is so comfortable around me, but also try to let her get the idea that she could help me be more comfortable by avoiding appearing in certain ways.

Fatalize

"I would tell my wife [that I saw her sister in her underwears]" famous last words

Adám

@Fatalize Sweetie, you know that I love you right? You are, and will always be, the only one for me. Not only that, but I want to make sure I'm never tempted by somebody else. Sometimes, that isn't as easy as it sounds. You see, men tend to have this crazy thing about female bodies, which makes it very hard for us to look away. Unfortunately, your sister feels comfortable going about while dressed in a way that makes me uncomfortable. Do you think we could have a talk with her together?

Stewie Griffin

My wife knows it, she sees her as much as I do. She doesn't think her sister does anything strange or wrong... I just have to endure it and pretend I don't find it weird either, while inspecting the flooring.

Fatalize

09:16

@Adám What she understands: "your sister is hot"

@StewieGriffin I mean if she doesn't think it's strange you can just look as normal…

Stewie Griffin

Hehe :-) by the way, it's not a problem.

Adám

@StewieGriffin Did you talk about it? Women can be unaware of the effects on men.

Fatalize

or ask your wife to dress the same way and look at her instead

2

Adám

@Fatalize So what? There will always be someone better-looking out there. That doesn't diminish my affection for you.

@Fatalize Clearly, SG is uncomfortable enough to discuss it in TNB.

Stewie Griffin

My wife would just laugh at me and say that I could just look if I wanted to. Not really the jealous type, since she doesn't have any reason to be. Nope, I haven't talked to her about it, but my wife knows very well that all men (even happily married ones) look at other women.

Fatalize

09:22

Well just enjoy the view then (if it's enjoyable, that is)

Adám

@Fatalize I certainly would feel like I'm cheating on my wife, even if she didn't mind.

Fatalize

Looking at attractive people is normal behaviour, I don't see how that's equivalent to actual cheating in any way

Adám

@StewieGriffin all men (even happily married ones) look at other women — no, all men feel tempted to do so, but many are faithful enough to not look.

Stewie Griffin

This blew up... I only mentioned it as a slightly funny thing that occurs in my house at the moment.

Ok, tempted. Poorly chosen words.

Adám

@Fatalize ~~normal~~ natural. Being civilised is a constant fight against one's animalistic nature.

Fatalize

09:25

@Adám You assume that all men share your definition of faithful

Erik the Outgolfer

@Fatalize of course, we can't just believe somebody over the internet who says that his "sister in law" walks in "only a thong and a bra", pics or it didn't happen...and better be high-quality pics, otherwise how do we know it's not really somebody wearing beige clothes

Fatalize

@EriktheOutgolfer under multiple viewpoints and lightings too, just in case

Adám

@Fatalize No, I didn't define faithful, but rather used it as a continuum, where at some point you cross the look/don't-look point.

Stewie Griffin

I'll have my camera ready next time. "Oh, I'm just taking pictures of the white walls".

Fatalize

@Adám There is no "look/don't look point" to me. I can look as much as I want without being unfaithful

Erik the Outgolfer

09:27

@Fatalize sure, otherwise who knows where in the internet the "pic" is from

Stewie Griffin

I don't remember which religion it was, but one of them claims that a bad thought is equivalent to a bad action. One of Abraham's.

Adám

@Fatalize Sure there is such a point, you just hold that it is fine to cross it.

Stewie Griffin

I agree with Fatalize on this one.

Adám

@StewieGriffin Orthodox Jews certainly try to stay pure in thought as well as in action, but there is still a difference in punishment for thought vs action.

Fatalize

@StewieGriffin Obviously since you just checked your sister-in-law :p

Stewie Griffin

09:29

Haha

Adám

@Fatalize But he's awkward about it.

@StewieGriffin OK, then use a different word than faithfulness. Maybe exclusivity is better?

Stewie Griffin

You mean I tried in vein not to check her out... :-P

Erik the Outgolfer

> If somebody goes out dressed in as little as possible, you may look at them as much as you want, as long as you're not touching them in any way on purpose. — Common sense

Adám

In Judaism, before marrying somebody, we do kiddushin which literally means to make one-selves exclusive to the other.

Practically, the groom says to the bride, Behold, you are set aside for me!

Stewie Griffin

Do married Jews never look a split second longer at a pretty face (or other body part)?

My wife: "I met Julie yesterday?"

Me: who's that?

Adám

09:36

@StewieGriffin Do they never? Obviously, humans are not perfect. They should never. Staring for pleasure at even the tip of a pinky finger is strictly prohibited.

Stewie Griffin

Wife: the really pretty one down the street.

Fatalize

@StewieGriffin Your wife is sending you a message, oblivious fool!

Adám

@StewieGriffin Happens all the time with me. I don't look at my wife's friends or female family members, and tend to not know their names either.

Stewie Griffin

:-)

Erik the Outgolfer

Jews be like: "I can't take my eyes off of you, beloved wife, you are and will always be the best"

Stewie Griffin

09:38

You don't know your wife's friends names? Why?

Adám

@EriktheOutgolfer ~~best~~ only one.

Stewie Griffin

On propose?

Adám

@StewieGriffin They don't exist to me. There is only one woman in the world.

Fatalize

Hope your mom doesn't read this

Stewie Griffin

What? Really? There are clearly other women... half of the world's population in fact.

Adám

09:39

@Fatalize She doesn't have the status of woman, only of mother.

Fatalize

@Adám The logics of religious people will always amaze me…

Adám

@StewieGriffin Sure, but they are just neutral people that I do not interact with other than for practical purposes.

Stewie Griffin

How about co-workers? Don't know their names either? Don't you talk to your wife's friends?

Erik the Outgolfer

@Adám so the best, no?

Adám

@Fatalize Obviously, I recognise that my mother is a woman. I think you get what I'm saying here.

Fatalize

09:40

@EriktheOutgolfer Obviously the best of a set of one element is that element, regardless of the definition of best

Adám

Adám

@StewieGriffin I speak with my female co-workers, but I don't chat with them. (Well, I try my best to politely wiggle myself out if they start chatting with me.)

The Masked Rebel

09:41

Hello

Fatalize

@Adám I would get what you're saying if you didn't say that you intentionally ignore other women's names, which seems utterly ridiculous at best

Stewie Griffin

I talk to then and interact with them the same way as I would a man. I find anything else to be sexist. Why treat them differently?

Adám

@Fatalize Why? If I needed to speak to them for practical purposes (like with co-workers) I would do so, of course, but for those I have nothing to do with, why should I know their names?

Fatalize

@Adám You have nothing to do with your wife's friends? So you don't care about your wife's life?

Adám

@Fatalize I have nothing to do with my wife's friends. That doesn't mean I don't care about her life. How do you make such conclusions?

Fatalize

09:45

I don't see how you can possibly care about someone if you don't even know with whom they interact on a day-to-day basis

Adám

@StewieGriffin My wife doesn't have male friends.

@Fatalize I know loosely who she interacts with, I just don't know their names. E.g. I know that last night, my wife went for a walk with a co-worker of hers. I know where the co-worker lives and my wife has told me things about her. I still don't know her name.

The Masked Rebel

HellOO

Stewie Griffin

Why though?

Fatalize

@Adám That's just seems like a ridiculous restriction that serves no purpose other than being symbolic for the sake of symbolism. But then again that's not the most ridiculous thing I see about religion anyway

Adám

@StewieGriffin I don't need her name. And knowing it would just bring somebody else's wife closer to me.

@Fatalize The purpose is exactly that symbolism. In a sense, I tell my wife that other women don't matter (as women) to me. (Obviously, they may have practical importance as co-workers etc.) And this makes her feel special and appreciated.

Stewie Griffin

09:51

"In a sense, I tell my wife that her friends don't matter to me, because they are female".

Fatalize

I don't see how forcingly ignoring other women is more symbolic than not ignoring them yet still being perfectly faithful

In fact, I would argue the complete opposite. You are scarred of "falling" so you ignore them, instead of showing your strength in the face of temptation

So even from a religious "temptation" mindset, it makes no sense

Stewie Griffin

I would feel more special if my wife interacted with super handsome, nice, fun and clever guys all day long, and still wanted to come home to me...

Adám

@StewieGriffin Not so; her friends matter to me as being my wife's friends, but in every gender-related matter, they don't.

@Fatalize What does that even mean?

Stewie Griffin

Wife and SIL calling. Will be back.

Fatalize

@Adám read Stewie's example

Adám

09:55

@StewieGriffin @Fatalize Interaction is a slippery slope.

Erik the Outgolfer

"Wife and SIL calling" dun dun dun...

Fatalize

@EriktheOutgolfer LOL

Adám

@EriktheOutgolfer Yeah, that sounds ominous. Maybe they do attend TNB after all…

Switches to on-topic mode…

CMQ: How does this sound (ideas, dupes, etc.) for a main challenge? Given an N-dimensional orthogonal (non-ragged) array, and an indication* of which dimensions to reverse, return the array but reversed along those dimensions. * E.g. a boolean list of length N or a list of a subset of the first N indices.

Erik the Outgolfer

@Adám hm, what if "reverse" could be generalized? also, "first N indices" might not be understood as "first N dimensions" or "first N positive/non-negative integers"

Adám

@EriktheOutgolfer Obviously, I'd flesh it out in the post, with examples etc.

@EriktheOutgolfer What do you mean by "reverse" could be generalized?

Mr. Xcoder

10:07

@Adám Example, please?

Adám

@Mr.Xcoder [[[1,2,3,4],[5,6,7,8],[9,10,11,12]],[[13,14,15,16],[17,18,19,20],[21,22,23,24]]‌] and [true,false,true] or [1,3] (1-indexed) gives [[[16,15,14,13],[20,19,18,17],[24,23,22,21]],[[4,3,2,1],[8,7,6,5],[12,11,10,9]]‌]

Erik the Outgolfer

@Adám "reverse", in this case, is a function that gets applied to some specific dimensions. what if a (black box) function is accepted instead of being "reverse" though?

Mr. Xcoder

Taking a black-box instead seems like an unnecessary complication to me.

Adám

@EriktheOutgolfer Would only work if the black-box function was a permutation function. The benefit of reversing is that the order of processing the dimensions doesn't matter.

Re-combination may also work, but only if length is kept.

Mr. Xcoder

CMC: Given a list of positive integer of length at least 2, return a (uniformly) random derangement of it.

Adám

10:13

@Mr.Xcoder Distribution? Do all derangements have to be possible?

Mr. Xcoder

Clarified.

Erik the Outgolfer

@Adám well, yeah, but at least it would focus more on the dimension part

Mr. Xcoder

[1,2,3] -> any of [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1], equally likely

Oh, I forgot to mention that the list will not contain duplicates.

Adám

@EriktheOutgolfer Why? The reason for choosing reversal is that it is a trivial operation (in most languages), so the challenge would be mostly applying the function to multiple dimensions. I'm sure many languages would be excluded (or it would be overly hard to participate) if I required black box.

Mr. Xcoder

I agree with Adám, reversal is imo the most reasonable choice.

Erik the Outgolfer

10:16

hm

Mr. Xcoder

Black-box wouldn't make much sense alone, unless you want to complicate the challenge and apply the function successively (not simultaneously) on the given dimensions, and account for dimension changes after the func's been applied... Which I don't like, tbh.

Erik the Outgolfer

for example, if the function is "swap every pair of elements, leave last as-is if length odd", that won't happen

Adám

@EriktheOutgolfer Yeah, that's a permutation function.

Mr. Xcoder

In that case the challenge would have to guarantee that dimensions are preserved => more work => -1 :P

Erik the Outgolfer

that must be an assumption, as long as we don't want to care about the order of the dimensions

and yes, such an assumption can be defined objectively

Mr. Xcoder

10:22

@EriktheOutgolfer Sure it can: "The function will be dimension-preserving "

A J

10:35

Everything has been handled. Y'all can continue chat. :D

Adám

@Mr.Xcoder That's not enough.

Mr. Xcoder

@Adám How is that not enough?

Adám

@Mr.Xcoder Let's say the black box function adds consecutive integers as it traverses. The structure is obviously preserved, but the order of application matters.

Adám

11:03

I'm curious, may a challenge require explanation of submissions?

Mr. Xcoder

11:40

@Adám Are you thinking about this?

Adám

@Mr.Xcoder I, I had not seen that. I was just thinking by myself.

Mr. Xcoder

Informally, I'd say yes (as in, a rule like that could be formulated as a request). But shouldn't be enforced, in my opinion.

Adám

@Mr.Xcoder I've given out electronic cookies in the past. Also, it is hard to specify objectively what an explanation is.

Mr. Xcoder

On an unrelated note, I've had many challenge ideas at random times in the last week but forgot every each of them :c

No answers for my CMC‽ But it's so easy :S

Adám

Adám

Mr. Xcoder

A-ha. I doubt anybody will submit anything in Pyth, so 4 bytes: Ot.p

dzaima

ah so this is wrong :|

Adám

@dzaima I think so.

1 can only occur as he two last elements, 2 as the first or last, and 3 as the two first.

@Mr.Xcoder ^^^

Mr. Xcoder

Hmm?

2 hours ago, by Mr. Xcoder

Oh, I forgot to mention that the list will not contain duplicates.

dzaima

@Mr.Xcoder that changes nothing about your example being wrong as it already had no duplicates

Mr. Xcoder

What's wrong with it?

dzaima

12:06

2 mins ago, by Adám

1 can only occur as he two last elements, 2 as the first or last, and 3 as the two first.

Adám

@Mr.Xcoder No [1, 3, 2] is not a valid derangement of [1,2,3] since 1 didn't move.

Mr. Xcoder

My definition of derangement is a permutation of the input that is not the input itself.

Should have been more clear.

Adám

@Mr.Xcoder But that's not what the word means.

Derangement

In combinatorial mathematics, a derangement is a permutation of the elements of a set, such that no element appears in its original position. In other words, derangement is a permutation that has no fixed points. The number of derangements of a set of size n, usually written Dn, dn, or !n, is called the "derangement number" or "de Montmort number". (These numbers are generalized to rencontres numbers.) The subfactorial function (not to be confused with the factorial n!) maps n to !n. No standard notation for subfactorials is agreed upon; n¡ is sometimes used instead of !n.The problem of counting...

Mr. Xcoder

The CMC uses a different definition, which I forgot to state.

Now move on :P

Adám

@Mr.Xcoder Should have been different permutation.

caird coinheringaahing

@Adám The style of learning totally differs between English and German though. The languages may be similar, but lesson content are like cats and dogs

Mr. Xcoder

@NathanMerrill Different branches of math

Nathan Merrill

then English and German are both branches of Language

Mr. Xcoder

@cairdcoinheringaahing Because you live in the UK.

fəˈnɛtɪk

Dynamics is the study of moving things and statics is for stationary things. They are clearly completely separate

caird coinheringaahing

@Mr.Xcoder Yes

Adám

@cairdcoinheringaahing I was thinking back to high school in Sweden.

Mr. Xcoder

@Mr.Xcoder Same as caird, maths and physics.

fəˈnɛtɪk

Biology and Org chem

@Adám I've just finished both French and German for GCSE and the lessons, at times, were so similar that only vocab was different

fəˈnɛtɪk

although I am thinking more of molecular biology than biology in general

Adám

@cairdcoinheringaahing Makes sense.

@Mr.Xcoder Philosophy and Religion.

Mr. Xcoder

lol I don't "study" either. But I see your point

Pavel

@Mr.Xcoder Computer Science and Study Hall

@Mr.Xcoder Math and lunch.

@Mr.Xcoder Bakery Science and Fermentation Sciences :v

Mr. Xcoder

@Adám That's a very intersting choice. Indeed, there is some deep connection between the path of the hand when one eats sandwiches and the graph of quadratic functions :)

Pavel

@Adám At our school, lunch is seperated into 3 time blocks: You either have A lunch then Period 4, Period 4 then C Lunch, or Half of Period 4, B Lunch, rest of Period 4

I had Period 4 Calculus and B lunch last year

In the second half of period 4 everyone would be eating since they used their lunch break to just hang out

Mr. Xcoder

At our school, lunch is separated into 0 time blocks because there is no lunch lol

Pavel

How do you survive

caird coinheringaahing

@Pavel Huh. That's the only other school besides mine that does that, that I know of

Mr. Xcoder

18:24

@Pavel We can buy food if we want, but only commercial food (chips, biscuits, sandwiches, ice cream etc.)

Pavel

A sandwich qualifies as lunch, does it not?

caird coinheringaahing

@Mr.Xcoder When do you eat that food?

Mr. Xcoder

In our very long 10-minute breaks :/ between classes

For two years in a row starting in a week I'll study in the afternoon (from 2:00pm to 8:00pm), so rip PPCG activity. Used to be at school between 8am and 2 or 3 pm...

@Pavel They're awful (as taste), to be honest... I prefer eating biscuits

Zacharý

Mine also does the A/B/C lunch, but during 3rd period.

@Mr.Xcoder Math + Physics.

ngn

18:52

@Mr.Xcoder music and painting - they let us "be creative" in both and do whatever we want, so most of the time we played cards :)

Mr. Xcoder

@ngn Exact same here, do true!

ngn

@Mr.Xcoder what games do you play? we were crazy about belote

Mr. Xcoder

@ngn Cool! Mostly Camps, "Macao" (which I think is called Rummy in English) and a very cool game called "Trombon" which I think is not known internationally (I can explain it to you if you want)

ngn

@Mr.Xcoder I'm familiar with Macao, it's called the same here in Bulgaria, but not nearly as popular as Belote. I'd be grateful if you can give links or a quick summary of the others.

Mr. Xcoder

@ngn Correction: Camps is Kemps in English, Macao is Macau and I'll explain the last one ASAP

@ngn Ok so here is a brief explanation of Trombon. The player count is recommended to lie within 3 and 8 players. All 52 cards are shuffled to the players successively. Then, the last one to be dealt a card starts a game. The gameplay follows this pattern: A player starts by saying <N = number of cards> <card number> (e.g. two queens 2 Qs / two fives 2 fives). They then place N cards face-down on the table. The cards could be of the specified type or could be something else instead.

Wait, the message was too long, let me add more messages :P

If any player (other than the one who just placed the cards) thinks they lied (e.g. instead of 3 fives they placed 2 fives and 1 six), they say Trombon

19:13

@Mr.Xcoder Not to interrupt, but are you up for a game of Codenames? I seem to remember you wanting to be pinged

Mr. Xcoder

@cairdcoinheringaahing Yes, I will join asap.

Thanks!

H.PWiz

@Mr.Xcoder We call that cheat, or bullshit in England

Mr. Xcoder

Then, that player checks the cards – If they are right, the other player must draw the cards back and then the one who guessed right starts another round.

Otherwise, they draw the cards themselves and the round continues from the adjacent player.

When a player has four of a kind in hand they are obligated to drop them. The one who first gets rid of all cards wins.

@H.PWiz Ah, I see. Thanks!

Pavel

@Mr.Xcoder "The player count is recommended to lie within 3 and 8 players" <-- lies

It's awful with 3

Mr. Xcoder

That should have been a 4, typo.

ngn

19:20

@Mr.Xcoder Thanks! I've never played such a game.

Mr. Xcoder

I hope you'll enjoy it if you ever do play

AdmBorkBork

20:09

I personally like President (Wikipedia) better, but Cheat can be fun.

Cheat is fun playing with "new" people -- i.e., people you don't know well so don't know if they're lying.

Pavel

How do I make the terminal be normal again after curses.initscr in Python?

Mr. Xcoder

@AdmBorkBork Exactly. I love playing in those circumstances.

Zacharý

20:31

@Pavel curses.endwin() I think...

Pavel

@Zacharý Oh TY

Zacharý

What are you using ncurses for?

Oh god ... ncurses + error screen = bad news

Pavel

@Zacharý Trying to clear the screen

Unfortunatly curses.endwin() restores the terminal to the way it was before calling curses.initscr

Zacharý

os.system("clear || cls")

@Pavel Unless CMD/Bash is blocked, that should work

Pavel

Yeah but calling os.system feels like a bad

Zacharý

20:43

for i in range(100): print("") :p

Pavel

Leaves the cursor at the bottom

@Zacharý This fails on windows if COMSPEC is powershell, which it sometimes is, so you're stuck checking os.name

Zacharý

Can some power-shell god tell me a way to polyglot that?

@AdmBorkBork we need your powershell godhood

Pavel

Hmm, "clear; return; cls"?

IDK if that works in CMD

And I can't check

Zacharý

IDK either...

Pavel

one sec installing wine

@Zacharý It does not

Zacharý

20:52

._.

Hold on ... I'll ask the polyglotters

Pavel

Maybe if you newline seperate it

Zacharý

Nah, bash'll complain about both return and cls

Pavel

@Zacharý You can return from an os.system call

Zacharý

Either clear or cls work

Pavel

So it'll never get to cls

Some for Powershell

Zacharý

20:56

Maybe then

Pavel

@Zacharý THIS doesn't work in CMD either

CMD's || doesn't short circuit

It executes the clear (and fails instantly)

Zacharý

I thought that was the entire point to ||

Pavel

Well you see, CMD is dumb

So

Zacharý

wat

Pavel

Hold on, you're right

It does check if both sides are valid commands though

Zacharý

20:59

Ah

Pavel

Basically, in Bash an invalid command is treated as a normal error, in cmd it's considered an "Abort! Abort! Panic!"

Zacharý

Maybe we could do ncurses magic with a 0x0 window or something?

What is this for, anyways?

Pavel

Nothing at all, why do you ask?

Zacharý

No reason, I think my friend had a similar problem (using C++ though) and just ended up using a bunch of std::cout << std::endls

@Pavel Then we need to find a way to move the cursor to the top.

Pavel

#if defined(WIN32) || defined(_WIN32) || defined(__WIN32)
system("cls");
#else
system("clear");
#endif

There's your C++ solution

@Zacharý ncurses

I'm sure there's a curses port for Windows

Zacharý

I dunno

Does Windows Python have ncurses?

I don't think so

And I remember having a hard time finding (n)curses for windows
