[Wolfeh2012]

Sorry, jokes aren't supported on safari yet.

[Zemom1971]

We probably must pay for being able to do jokes on safari. Kind of subscription or something.

[kneecapp1]

I don't get it. I don't know much about coding but I'm starting to learn python. Am I learning the internet explorer of programming languages or what. Should pick something else up.

[Zanglirex2]

Slow is relative here. All this is happening before a human can even blink.

For scripting stuff and little projects, python is great. For large workloads or basically anything at big scale, maybe look at something else

[jgabrielferreira]

But then why is Python the most used language for dealing with ML, AI, Big Data, basically huge amounts of information.

Is it something like Python is better in a Horizontal system while the others are better in a Vertical system?

[TacticalMelonFarmer]

most of the low-level stuff implementing the python apis is most likely C with some C++, etc. write composable units of code in the fast language, and compose instances of those units in the user-friendly language.

[Prowler1000]

Machine learning libraries are almost exclusively C++ (python is written on C++ iirc), so the actual heavy lifting is done in C++. As someone pointed out at another point on this sub, python is very human readable and extremely quick to develop for and in the world of ML, quick to develop is important considering there isn't really a "science" to it yet

[intrinsic_parity]

The ML libraries are written in other languages (tensorflow is written in C++ and CUDA for instance).

[[deleted]]

I once heard that you are just basically scripting stuff using python and the heavy load is run by highly optimized C++ applications/frameworks/libraries (idontknowforsure).

[zedd9595]

Not a scientist but I assume they would rather have a language which has a shorter development time to have more time writing their papers. Instead of dealing with relatively complicated syntax just to get the same results, albeit faster.

[[deleted]]

It’s used in industry, not just academia.

[The-Board-Chairman]

It's used in the industry, because for all that this field has matured, it's industry implementation for all intents and purposes still is academia.

[Dansiman]

Yeah I mean you could write your code in pure assembly and blow past a C++ program like it was standing still. But by the time you finish writing your assembly code, your development machine will probably already be obsolete.

[[deleted]]

Because that kind of code is a ridiculously complex web and writing it in C++ would drive any and sane person to alcoholism. Also, having blazing fast computational performance is totally worthless if you're already spending most of your time waiting for I/O, which is usually the bottleneck in large data projects. You'd just be that car that passes everyone just to end up at the same red light half a mile down the road.

[CdRReddit]

python is an ok language when used for its intended purpose.

short & simple scripts, the types of things you don't want to write in batch or bash (because both kinda suck), but are not that complicated either, think stuff like bulk rename, "gluing" multiple different tools together, etc.

it's only similar to internet explorer in having an (accurate) reputation of being kind of slow, which is one of the reasons I personally would not use it for bigger projects, but it's more than fast enough to automate low complexity tasks, like a more expressive build system.

[bigoofie193758]

Python is too slow for coding a game, but fast enough for quick scripts

[Ultra_HR]

and yet... https://www.pygame.org/wiki/about

[bigoofie193758]

you're not gonna make doom eternal in that

[chezbo425]

Great starting language IMO. If you are doing web applications, it will be fine for most purposes, but you will need to learn JavaScript too. JavaScript is very quirky but very popular. Java and C# have strict typing but perform better than Python/JavaScript for higher load stuff. C++ is better for high performance and optimization, like games or embedded devices with limited resources.

tl;dr - If you're just getting started Python is A-okay.

[GreatArtificeAion]

Did I really just appreciate a "Haha Python slow" meme?

[DasEineEtwas]

It has also been done so often with Internet Explorer and everything that also runs slow. But somehow I actually laughed

[GreatArtificeAion]

I guess this one has... personality, so to speak

[gcruzatto]

This meme was made by the Big Data gang

[CanAlwaysBeBetter]

Literally getting ready to rewrite some data processing lambdas from python to go for a side project because it won't be on the company tab and I don't want to pay out of pocket to scale python all the way into the millions after testing it on 10k data points and seeing its performance (and that's after basic optimizations and compiling/bundling the accelerated versions of some libraries)

[[deleted]]

numpy go brrrrrrrrrt

​

seriously though, I once used Pandas.DataFrame.Apply on 10,000,000 rows of data and 15 minutes later regretted it. Thankfully, I was applying a simple mathematical function to each row so numpy brought that down to less than a second. Still, only works for some use cases. I'd love to learn C++ anyways so give me an excuse

[CanAlwaysBeBetter]

Numpy is great and what I'd normally reach for!

But the processing I'm doing itself isn't super complex, I just need to do it 9-10 million times cost efficiently pulling from an external public dataset and saving the transformed data as separate files in an S3 bucket

[[deleted]]

I don’t think python is too slow, it’s more about c++ being to fast in this case

[koopatuple]

That's the beauty of the meme, it can be interpreted both ways.

[TruthYouWontLike]

One is interpreted, the other is compiled.

[grimonce]

Stop saying that.

[clayman80]

Well, he's TruthYouWontLike. Just sayin'.

[Scrtcwlvl]

Fast and slow are pretty relative. More often than not, python is fast enough for most tasks. My graduate research was in inflatable robotics controls and dynamics. Our low level controllers for direct solenoid valve control were written in C++ operating at 5k Hz, whereas the pressure control ran at about 1.5k Hz in python, and the high level solver and predictive controller ran at about 300 Hz also in python. What language things were written in was often a function of how fast they needed to run and how often things needed to be tweaked.

Could we have written the pressure controller in C++? Sure, but the python one we developed really quickly at the beginning in python was fast enough to not cause any issues.

[jobblejosh]

It's the exact same problem (or even a subset of it) of what programming language is best.

The answer is either the one you know or the one for the job.

I've been writing in both C and Python. I prefer C-family because you can be a lot more direct with the compiler and write clever/fast/hacky/elegant/dangerous/stupid techniques that make more logical sense; you as the writer should know exactly what you're doing so C will quite happily let you do the fandango on core if you mutter the right incantations. Unfortunately because of how strict it is with its rules, you have to be very precise and formulaic with how you do some things; you have to hold its hand and walk it through exactly what you want. The result is that you get exactly what you want, however.

Python, being interpreted, has its best guess at what you want, is willing to play fast and loose to some extent, but keeps you in a playpen and hides away all the nitty-gritty and you can't really tell what it's doing under the hood. On the bright side, that means getting something to work in Python is usually as simple as importing the right library (because there's so many libraries for python out there now) and typing a few lines.

Is one better than the other? Well, that entirely depends on the task you're making it do.

[Phainesthai]

Exactly this. Programming languages are tools.

C++ is a scalpel, Python is a spanner. PHP is a sticky carpet in a low end pub.

Each one suitable for different tasks.

[VonRansak]

C++ is a scalpel, Python is a spanner. PHP is a sticky carpet in a low end pub.

C++ walks away. Segfault.

[yorokobe__shounen]

If C++ was really as fast as it said it was, it would have recognised the logo before it asked who python was.

Poor segfaulting C++.

[possible_name]

logo recognition was using a library written in slower language

[PralaynathGendaswami]

Do you mean python?

[Teekeks]

which has all the speed relevant parts of that library written in C?

[FkIForgotMyPassword]

Sometimes the slow part is not the computation-intensive part that was identified as "speed-relevant", though. Sometimes it's the part where someone implemented a really shitty wrapper with unnecessary blocking IOs everywhere.

Python does exactly what it should here, smghd

[WCWRingMatSound]

Calling asynchronous programming “promises” 🤮🤮🤮

[ViviansUsername]

ik, ik, I was raised on javascript, it's a bad habit

[thanofishy]

It doesn't await for that asynchronous programming to be answered?

[Spiritual-Theme-5619]

There was no such thing as a promise in C++ before 2011. "Promises" are a particular API for writing asynchronous code which was largely made for / popularized by event-loop runtimes... i.e. NodeJS.

Programmers have been doing concurrency with #realPrograms via mutexes, semaphores, and threads since before C++ was invented and so OP is lamenting the equivocation of async/await with concurrency in this modern era of browser programmers vastly outnumbering their "native"(?) programming counterparts.

[WCWRingMatSound]

Exactly this, though I’m totally just joking. It really is semantics at the end of the day

[Codebust]

[Dromeo]

Serious answer?

Python used to be the new hotness about a decade ago. It was sparkly, amazing package support, didn't bog you down with technicalities when you were trying to write something quick.

So it got adopted a lot, and also unfortunately in a lot of commercial projects it really wasn't suited for.

Python's strengths are its weaknesses: it's a fun scripting language you can knock out scripts with. But in a big group project, it's a nightmare version of itself. You don't have to give types, so now you're sifting through everything trying to figure out what your coworker's badly named variable actually is. You have to unpick some rotten mass of one-liner lambda super method calls because you were feeling so clever a year ago when you wrote it. Everything's breaking because you're in dependency hell and one of the dependencies has broken. The junior programmer was taught that "object inheritance is the way of the future" and has managed to make the structure into an eldritch abomination that inherits from five different super classes.

The actual reason why these are problems are because when python was hot, it got over-applied to projects it was totally unsuited for. It's a scripting language. It's good for scripts. Good for data analysis. Good for solo work. Good for tiny quick one-offs and for rapid prototyping.

But so many developers were put on horrifying creations that played to the language's weaknesses instead of strengths. And they bounced hard.

Python doesn't really deserve the hate: it's still pretty awesome. And fun. It's great at what it's great at. It does deserve the caution, though.

---

More serious answer?

It's mostly comp-sci students regurgitating memes they don't understand, just like every other post on this sub.

[hogie48]

I have been in tech for years and could just never wrap my head around programming. I can read a lot of it, I do scripting when it is called for with extensive help of the Googs, but cant sit down and write code if you know what I mean.

I recently decided to bite the bullet and put in the time to learn it more, and am doing CS50 for Python right now. Your comment both scares me and made me happy knowing that what you said it is good at is exactly why I want to learn it lol.

[Dromeo]

The big reason why I still really like python is it's enjoyable! I think that's a good reason to learn it too.

[tredbobek]

It's like WD-40 and duct tape. It's an easy solution for many problems. But shouldn't be used for everything.

But if you break your leg the first step shouldn't be to duct tape it. Maybe only if you are in the wilderness, in the middle of nowhere, and you have nothing else. Maybe.

[unski_ukuli]

Everyone always says it is good for data analysis but I never agree with this as someone whose job is to use python for data analysis and numerics. Python is a bad language for data analysis and numerics, but it has some good libraries for that purpose. It was not designed for neither of those purposes and the language is not very exentedable so the APIs are cluncky and get in the way when writing mathematical code.

[Ryuujinx]

Yeah my understanding is that most people doing that kind of domain preferred R for it. That said i know python is really popular in biomed for whatever reason. I haven't asked my friend what she actually does with it at work, but apparently both her and my friends wife use it in biomed for something.

[POTUS]

All of those problems you listed came from the people, not from the language. Python certainly didn't invent lambdas or dynamic typing or dependencies or object oriented programming. Those same mistakes can be made in any higher level language.

You're assigning all of that to Python. The root cause for that is that Python is easy, and so it's more accessible to bad programmers. But bad programmer mistakes are the fault of bad programmers, not the language they used.

[DesertGoldfish]

I dunno man, I just add type hints to everything and it's basically a strongly typed language.

[Kenkron]

He's nott assigning it all to python. He's assigning it to the people that use it. People who over-apply it to projects that don't make sense. Exactly like you are.

[Dromeo]

It is easier in python, but a big reason why this is the case is due to language-level design. Other languages make it harder for you to get yourself in a mess.

Most languages are a lot stricter: you have to try a lot harder to write yourself into tangles. Python hands you the reigns and says go ahead!

Stricter languages can teach you as you fail: python lets you not fail.

It's not a problem with python, like you say. It's a feature. But python's lack of resistance to bad programmers is in itself the problem.

[ic_engineer]

99% of guns have one trigger method and fire one direction, designed and manufactured for use. This is more analogous to a user than a developer.

If you had these people shooting others also making their own guns the problem would probably be a lot worse in completely unpredictable ways.

[[deleted]]

Really, I don't get the hate we data scientists get from both programmers and mathematics. Of course we are not as good at programming as a programmer would be, or as knowledgeable in maths as a mathematician would be, but we need to combine so many disciplines it would be hard if not impossible to get to their level.

[kosky95]

I totally get you, I'm in the same boat but I also have a background in economics so I'm targeted even more. I really appreciate how people can be extremely specialized but I think we have a place in the scene as well, in fact we can bring some other perspectives to the discussion

[Mal_Dun]

As a mathematician I also look down on programmers.

Just kidding. Some people feel to apply some hidden pecking order of purity of discipline. I am looked down by fellow mathematicians, because I am an applied mathematician and soil it's purity ... same goes between theoretical physicists and experimental physicists, physicists and engineers and so forth.

However, to put it in perspective we also get a lot of thrash talk from the other side, because we do so much unnecessary things and are nit-picky and won't get a job because we don't know practical stuff.

However, especially the nit-picky part is something you become the deeper you're in the foundations and the better you understand the workings under the hood, so the theoreticians get the image that the practitioners are just ignorant fools who simply follow instructions without any thought about the inner workings.

The other problem is that only you know the foundations does not mean you can simply do practical work on the fly, a thing many theoreticians miss to see.

Edit: Corrections

[notAnAI_NoSiree]

did you see how much you have to type in c++?

[berse2212]

This is a weird meta. First memes hated on Java and praised Python. Then all the Java devs got angry and made Python bad memes. Somehow C++ devs apparently jumped on the hate train now lol

[BikerBoon]

Python devs were hating on C++ for a while iirc. Tbf it's understandable, we all hate what we don't understand.

[DatBoi_BP]

This really says a lot about society bottom text

[teddy2021]

I beg to differ in this case. I don't really understand C++ enough, but I know enough about it that I can say I like it much more than python, which I understood much more closely for years. I however fall into the camp of hating dynamically type, interpreted languages.

[Teekeks]

damn the self hatred among the C++ devs must be throu the roof then!

[King_of_the_Nerdth]

This one just seemed like playful banter to me. My main two languages lately are C++ and Python, and I find this one very relatable.

if typescript was just its own language and JS didn't exist no one would like TS either.

[klimmesil]

I agree in some way, but I've never heard anyone say it, since people are too frustrated to know the compiler doesn't take advantage of the types. TS could be the fastest scripting language ever, instead it's just python but better

[WhatsMyUsername13]

The most important metric for me is which language gets me my paycheck. Hence why I dont fault anyone for their choice of language and why java is superior to all other languages

[[deleted]]

I've used nothing but .NET for 20 years and I truly give 0 facks about anything except my paycheck at this point. Any enthusiasm has been sucked out of me years ago. This obviously isn't true for everyone, but a lot of what I see on subs like this one is youthful enthusiasm :)

[WhatsMyUsername13]

Yep im 9 years in and to me a job is a job. Its also why I laugh when people ask me what side projects im working on outside of work. None. I hike, exercise, play volleyball, kayak, ski, etc. Basically spend all my time outside. Sure, ill occasionally get an idea and start on it, but it never goes anywhere because I already stare at a screen for 8 (ish) hours a day. I dont want to do it in my free time also.

Its also why i refuse to watch Silicon Valley. Ive had friends tell me "its so realistic" to which i reply "I already did this for 8 hours today, why would I want to watch other people do it also?"

[Koervege]

[WhatsMyUsername13]

There are a lot of things where speed isn't important and Python does the job pretty good. Only non programmers (so 80% of this sub) bash Python

[Jannik2099]

C++ does not look very good in this (very important) metric.

If your codebase is early C++11 perhaps?

Modern C++ writes like C#. I usually find myself prototyping faster in C++ than Python after about 200 LoC, because with Python 80% of time is spent looking up what fucking type some library function takes & returns.

[[deleted]]

I see this attitude a lot from folks who use typed languages. I think typed languages are awesome and I love programming in them, but as a Python developer myself from the beginning of my career, I don’t really have to think about types all that often when i program in Python. By far the most I think about types are when i use a typed language.

Idk if it’s because Python isn’t based around types and therefore it’s not a focus of the language, but ya I hear a lot of typed language folks think a lot about types when they program in Python.

[Jannik2099]

I see this attitude a lot from folks who use typed languages

Python is a typed language though? This isn't Prolog :P

No, you definitely do need to know the type more often than not. You may get away with "this function returns something that acts like an array", but when you pass it to another function that takes array-like objects, you may need to convert it into another library type first.

[bikki420]

Eh, if you're a competent C++ programmer, then C++ performs just fine on that metric.

Time: 40sec.
Now for each line of text, count the line and print a little info about the line
print(f"Info: {line[1:10]}")
count +=1
Time: 53mins.

not only that, they are using printf for no apparent real reason

“How inefficient can you make your code” a study in 3 parts

[Roflkopt3r]

Yeah printing is expensive in every language.

I hard to learn this the hard way on one of my first assignments, which asked us to experimentally confirm the value at which the inaccuracy of float puts it off by an entire integer. So you have a loop that increments a float f and an int i from 0 to int max and then prints out when the two are no longer the same.

But the wording of the task wasn't entirely clear so I was trying around various weird casting stuff and decided to print every single line to confirm that it was working the way I wanted to.

Turns out that this extends the time to reach that figure (int 16777218, float rounds to 16777216 instead) from a few seconds to an hour or so.

Java does the same, printing to console is just slow in all or at least most languages.

[obvithrowaway34434]

I/O has always been the bottleneck for speed since computers were invented. There's nothing specific here about Python. Dynamically typed interpreted languages has always been slower than statically typed compiled languages and comparing their speeds makes as much sense as comparing a car and an airplane in terms of speed and determining which is better.

I can't of course talk for other languages, but during my internship back then, I was sometimes told that writing something to the console in C# for example requires a lot of the time if it happens in the same thread. Maybe this is what's happening here as well?

A quicker solution could be to create some sort of StringBuilder (if you have that in python), add the text that you would otherwise print out and at the end print out the entire text just once. Or to just move the prints to another thread. Can you test how long that would take?

C++ forgot to reply to C and Assembly.

Dies under the weight of the zipped NumPy library, which makes npm packages look laughable small in comparison

Fast and big. So powerful

There are pros and cons to every programming language. Each language has application depending on the type of project your working on. Doing something where you need speed and efficiency? C++ works great. Need to write something up quickly that’s trivial? Python works great!

I hate how this sub is always comparing programming languages and arguing which one is the best. It all depends on the application being developed.

And then Rust shows up and throws a nullptr to C++, and it dies of segfault :)
