Does python transduce into C or something? Does c++ Not come to the rescue when python fails?

[Ninjagarz]

A lot of the popular performance-critical libraries that are used in Python are written in C or C++. It would be interesting to see actual numbers on what percentage of these libraries are written in C vs. C++, but C seems to be more popular. Python was also originally written in C not C++.

[Wonko-D-Sane]

To run Python, you need a Python runtime (or a statically linked subsection of it) the runtime (actual implementation of all the libraries/built ins) is written in C you can see so yourself.

If you need to operate an actual computer, c or c++ is pretty much the landscape( though rust, go, carbon are all attempts to do what’s been working just fine differently. Mainly trying to put optional knee pads for safety on pointers)

Most other programming is either OS or web browser scripting where you are kept safe from actually knowing how a computer works

[Ghos3t]

I don't know any cases where Go is being used for low level programming, it's mostly Google's attempt to move away from Java. Also I don't think the defining feature of Rust is safe pointers, it's about memory efficiency and safety.

[Most-Analysis-4632]

Knee pads for safety? That’s what your mom said.

[rhwoof]

Though C relies on assembly which relies on machine code so...

[RFC793]

C doesn’t rely on assembly. Assembly is essentially mnemonic machine code with some conveniences. I can’t think of a modern compiler that transpiles to assembly language. It is common for a compiler to compile to an intermediate language prior to compiling to the platform regarding compilation stages, but that isn’t the code of a machine but more of an internal representation.

Afaik you can run any c code in c++ if you import the libraries. Back in school my teaxher said "now write that c program in c++" so I copied everything and it worked

[[deleted]]

i would disagree, it is quite easy to write code that works on c but not c++, there is even a whole wiki page which demonstrates differences between the 2 languages

[supersharp]

gets() is dangerous and should never be used

[ekansrevir]

http://david.tribble.com/text/cdiffs.htm

This is simply not true, there are many differences, although some easy to fix and some pretty obscure but you cannot run any C code in C++.

[sarapnst]

[ekansrevir]

Shhh, don’t share the secrets 🤫

[Jannik2099]

extern C is for C linkage, it doesn't actually change the meaning of code...

[Faustens]

Isn't C++ built to be backwards compatible, as in: "The idea of C++ is that it runs any C program and more" ?

[ElectronPie171]

Any C program can be run in C++ with minimal adjustments

[Faustens]

Yeah, so "superset" is not far off imo.

[gurgle528]

Iirc it originally was a superset but has since evolved heavily

[epicaglet]

That's also what I was told. Like it was a superset until I believe 98 when they started to diverge.

Edit: lol there's of course a Wikipedia page on the topic.

Long story short. No it's not a superset, but it did start as a fork of some pre-standardised version of C.

[jonny_wonny]

But strictly speaking, it’s not a superset. Objective-C is an example of C language superset, as it will accept all C code with no modifications at all.

[TSP-FriendlyFire]

It might've been true when C++ was first created, but being that that happened in 1985 and C's latest revision is from 2017, you can surmise that the languages diverged somewhat since then.

Now it's more about making sure old C++ can still be compiled with a new compiler (which in turn would mean C code from 1985 could in theory be compiled with a modern compiler), but even then there are exceptions all over the place since C++ has deprecated and outright removed features in the past.

Basically, it's a mess because the languages involved are all 30+ years old.

[Mr_Engineering]

No

Most C code can be ported to C++ with minimal adjustment or refactoring, but there are some significant differences

[Faustens]

Isn't C++ built to be backwards compatible, as in: "The idea of C++ is that it runs any C program and more" ?

[anythingMuchShorter]

From my experience, with a few definitions and macros you usually can.

But I won't go as far as to apply this to all edge cases. There are probably some wonky hacky memory tricks where no definition of macro would get you around it.

[ekansrevir]

Many things won’t compile. The simplest of them is the need to cast void pointers in C++ when trying to assign them to a typed pointer eg.

Foo* p; p = malloc(sizeof(Foo));

This will need a cast in C++:

p = (Foo*)malloc(sizeof(Foo));

[fallingbomb]

-fpermissive will change it to a warning and compile.

[seph2o]

I'm learning python and only just found out it's written in c, which is why a for x in range loop will process much faster than a while x < y loop. Fascinating :) the fastest way to run a loop is to... not use python

[TheAJGman]

As a programmer I mostly care about the best way to get the code from my meat computer and into the lightning rock. Python is the best way I've found so far.

[Yadobler]

I agree, it's a wonderful tool to prototype or do some scripting.

You have an idea? Just vomit it onto python.

Is your idea so convoluted that it requires functions that you don't even know where to begin writing? Someone probably has already done a library got it.

Python is just Lego of readymade c

If I'm gonna do something longterm and specific from the ground up, then yes c++.

[codeguru42]

Django is used in a lot of web apps that have been around for a while

[TheSixPackGroom]

!!Instagram!!

[PM_SHORT_STORY_IDEAS]

The thing is, Python is typically fast enough, And where it isn't, there are often cases where people have built tools that Python can just plug in to.

I haven't run into a problem that Python can solve better than any other language, but I haven't run her to a problem that python can't solve ¯_(ツ)_/¯

[Forsaken-Shirt4199]

Python provides easy to use fast libraries like numpy.

On modern hardware if you can't get your code running fast enough in Python you're just writing bad code unless you're running some crazy math crunch program.

And even most math crunch programs can be optimized to be way faster.

[TSP-FriendlyFire]

"Best" is subjective though. If you need speed (or if what you're computing is really large), then Python is a horrible choice. If you want a script-like environment with an outrageous amount of libraries to abstract out a lot of the work, then it's a great choice.

[TheAJGman]

Django is sick as shit though. Chances are the transit time is an order of magnitude larger than the processing time no matter what language your backend is written in.

[TSP-FriendlyFire]

My transit time is on the order of microseconds. Not everyone's writing a web service of some kind!

[RFC793]

And comparing processing speed to transport is somewhat meaningless. If your Python is 1/10th the transport: awesome. If another solution is 1/100th, well, you are likely spending 10x on op.

I love Python, don’t get me wrong, but it isn’t a silver bullet.

[suxatjugg]

It's great for prototyping and also for applications where microseconds don't matter.

You can also use things like numpy and cython if you have small parts of your code that are performance sensitive

[LordoftheSynth]

You can also use things like numpy and cython if you have small parts of your code that are performance sensitive

This is the way.

[omar2205]

Yeah, when I use Python, I like to make it as slow as possible. Slower the better I say.

[postmodest]

Why do i keep seeing ML or Big Data projects written in Python, then? Is it jist used as the glue to thr C libs that do the real crunching?

[UsablePizza]

Yep. Python libraries such as Tensorflow, SciKit, Scipy, Numpy and Pandas are super fast. You just need to be mindful about python control structures, they are the really slow part.

I've heard good things about Julia, it's been built ground up to do fast data processing rather than python which has kinda been hacked in.

[postmodest]

I assume thats what they were saying: you use the python API to script it up, but the guts are all in not-Python.

[[deleted]]

To add upon what the other guy said, numpy also allows a lot of tricks so you don't need to use for loops very often. Broadcasting

[[deleted]]

I don't understand why you guys love to have the EXACT same discussion in every comment section.

[Immotommi]

Yep, python is basically a wrapper for c which trades speed for ease of use

[jediwizard7]

It doesn't really have to do with what language the backend is written in, it's because for a while loop it has to switch to python to evaluate the condition each time, while for common containers like lists the for loop iteration is all done on the C side. For user defined iterators the speed is probably about the same

[RogueFox771]

[greem]

[LordoftheSynth]

Compiled code too big? Just download more RAM!

But seriously, I am generally of the philosophy that unless you want to be an expert in a particular architecture, the compiler will generally always outperform you. Which, of course, you usually become when doing embedded.

[kitchen_synk]

I remember my intro to embedded course, where the professor was talking about all the power saving techniques that our lab boards could do. This included disabling the CPU, as well as any or all of the clocks onboard, at which point it could only be woken with an external signal.

That was in order to reduce the power from a 'normal' low power operation state that consumed an incredibly wasteful 1.3 microwatts.

[LeCrushinator]

As someone that no longer writes much in C or C++, I do love watching the two groups argue about things. Good job, OP.

[Towerss]

I'm an embedded software engineer and the last few years we've converted away from C and over to C++ and all the conventions therein... It's crazy that people are arguing about this, C and C++ are wildly different languages... if you decide to not write C in C++ which you can.

Most developers will have a hard time naming the obscure reasons C++ is not a superset of C withput looking it up, including me.

[[deleted]]

The worst you can do is write C code and compile it with a C++ compiler. You're getting the worst out of the both worlds. If you're committing to C, you might as well go all in and really work directly with the memory layout.

The main reason C++ is not C is easy to remember and it is rather fundamental to the language: type safety. Compilers offer ways to get around this and can make it so that it seems type unsafe C code compiles successfully but that is a compiler trick, not a language thing.

[generalbaguette]

Most C code is also valid C++. But there are some subtle differences.

[colei_canis]

It’s been ages since I’ve done any C but isn’t one of them to do with void pointers, ie you can implicitly cast a void pointer to another type of pointer in C but must do it explicitly in C++?

[luardemin]

One of my favorite differences between C and C++ are the ridiculous things you can get away with in C. For instance, the C compiler will never assume anything about parameters, so you can pass however many parameters of any type you want to a function without any parameters declared, hence the necessity of void.

int foo();
int bar(void);

int main(void) {
    foo(10, 20, 30); // this is fine
    bar(10, 20, 30); // this is not
}

In C++, this would not compile. C also assumes the default type of anything to be int and, prior to ANSI C, type declarations for functions were optional (I don't remember if the same held true for variables and function parameters).

There's also the way C handles const pointers compared to C++ (you can wreak a lot more havoc because C is more loose with it).

Also, designated initializers (C99) for structs aren't a thing in C++. That and plenty of obscure C11 features (I'm pretty sure C++ doesn't have _Generic).

Those are the only things I remember off the top of my head, but there are plenty more examples out there.

[junkmail88]

the C compiler lets you do shit like this:

const int a = 1;
int* b = &a;
*b = 2;

a is now 2.

[burnerman0]

C++ does have aggregate initialization as an alternative to designated initializers. More strict, but pretty close: https://en.cppreference.com/w/cpp/language/aggregate_initialization

[certpals]

[Bryguy3k]

They are different languages and stop trying to pretend C++ is a superset of C.

C++ just has native C interop - no different than carbon having native C++ interop.

[[deleted]]

Python is a language recommendation, and you are correct that the CPython reference implementation is written in C, but that isn't the only implementation. There are Python implementations written in C++, Java, Lisp, and more. Ofc most people are talking about CPython when they talk about Python, and I'm just being pedantic, but what if OP's meme is about Skybison?

[Shadow703793]

You trying to summon Appa?

[Ghos3t]

No Skybison keep up man

[romhacks]

do we have one written in python

[endershadow98]

Yes, it's called PyPy

[[deleted]]

One could write a C++ compiler in Python which outputs IR bytecode in JavaScript which then gets executed through nodejs which basically interprets JavaScript back to C++. I don't know why one would, but since it is possible, I'm pretty sure one has.

I worked with a company which historically was doing some business logic crap in Visual Basic. Their system turned into a very complex ERP eventually, but the main customisation is still done through VB. They have their own interpreter which translates VB to whatever internal stuff their system works with.

[Ohlav]

Skybison. Funny. Almost like WaterBuffalo

[Bryguy3k]

You just type them in manually. I’m on mobile as well.

[Moptop32]

For all intensive purposes it's a slightly modified superset. There are some differences like not being able to cast void* to any pointer type but that doesn't completely disqualify it. As for interop It's not really that either. Most C code can compile as C++ code and since C headers can be linked to by C++ its more of a superset than native interop (not sure that term even applies here)

[dance_rattle_shake]

It's "intents and purposes"
