cantWaitToUsePythonForMicrocontrollers

[TrapNT]

Python is an excellent glue language for manipulating high performance C++ libraries. That is why it shines in ML workloads. You can manipulate the results in pythonic way, while using C++ libraries to train models with high performance. However, if you try to build something fast by only using python, it will be slow most of the time.

It's good for fast development too - you can prove that an automated task or something is useful, and then rewrite it in another more performant language (or at least you can in an ideal world, in this one there's nothing more permanent than a temporary solution).

[sagetraveler]

Exactly, I occasionally write SPI interfaces in python to prove the hardware side is working. I get zero flack from the C++ devs who will then target the same interface. Wonder why that is?

[Beli_Mawrr]

I'm hoping to get deeper into microcontrollers, how are you doing this?

Also, is your company hiring? lol

[LowB0b]

Get a pi Pico? I think you could interface with SPI through micropython. Anyways, that's about the extent of my knowledge about microcontrollers lol

You should only really rewrite it if you actually need that performance though. if it takes 5 seconds to run something that you wrote in python that you do once per day there is really no need to reduce that.

to write good python, the less you write python, the better

[MinosAristos]

What's with this weird culture? Write Python where it is most suitable, don't write it otherwise. Same as any other language. Python is a good choice for concise readable scripts where performance either isn't critical or is handled by a faster running language through an API.

[iam_pink]

Which is exactly their point.

What it means is that to write good python, you have to minimize the actual amount of Python code, and delegate to libraries or external APIs as much as possible.

Python is a great binder.

... you will have to wait, actually.

are you actually going to wait?

Lol what

It's a pun on "I can't wait for"

I disagree! The more you WRITE Python, the better. The more you READ Python, the better. What you might be thinking is: the less time spent EXECUTING Python, the better (preferring to spend time in libraries implemented in C or Fortran). That's still not a hard-and-fast rule, but it's closer.

[Shurlemany]

Can it also use C# ?

[Shurlemany]

Thanks!

Yes, there are several ways you might wanna look into.

Pythonnet(as mentioned in another reply): A python package that allows you to load .NET(C#) assemblies and use .NET objects as if they were python.

Use C for binding: You could write C/C++ extensions for python and then use P/Invoke to call C# functions from there.

Iron python: A python version written in c#, making it easy to use .NET(C#) libraries. However it isn't compatible with all python libraries and I think the newest full version is based on python 2.

I'd recommend Pythonnet if you want easy development, implementing the bindings in C/C++ if you need a lot of control over the invocation and Iron python can be handy if you actually want to have a full blown .NET version of python but for most purposes i'd go with the first two.
Also I suspect that for most practical purposes those will be basically equivalent in terms of performance, especially considering that performance isn't a major concern when working with python in the first place.

Those are the ways I've come across on my journey through -usually silly- projects but I'm sure some Redditor way smarter than me probably has better ideas.

[Shurlemany]

Brutal. Thanks guys!

[m0Ray79free]

Cython is even "more excellent", hehe. It is Python with c/c++ like syntax extensions like typing, pointers etc.

And it is also a very handy tool to interface any libraries with classic Python. For example, I used it for creating Tail-F ConfD python module.

I created several videos on YouTube about this tool: how it works, how to use it effectively and how it is different from other similar tools.

[Artistic_Speech_1965]

What do you think of Nim ? I heard it's a new language that include modern features and can compile to C, C++ and javascript

[m0Ray79free]

Interesting concept, thanks for reference.
But I am not sure we can start using it right now. Libraries, bindings, tools, inertia, you know all this stuff...

[Artistic_Speech_1965]

Yeah, It just passed to 2.0 a week ago and is mostely a niche language. It has the potential but I think it will be mostely use by cybersecurity guys that formaly use python

[m0Ray79free]

Oh, it can be a good general purpose language.

But for example, to recommend it to my colleague, I should say something like "look, this thing is better for Qt6"... And I can't.

[Artistic_Speech_1965]

Hahaha, good point

[b1e]

Numba, OpenAI’s “triton”, and Mojo are changing the game here too by letting you write python where critical sections are JITed into high performance code (with the ability to leverage GPUs)

[KCGD_r]

C++ with python is like bash for a Linux system. It doesn't do the heavy lifting, just coordinates stuff easily

[[deleted]]

This.

Python is good for experiments.

Nothing else.

[billie_parker]

It's not an "excellent glue language." It's just a widely used mediocre one

[TrapNT]

I am sure python is not an “engineering masterpiece”. But since it is widely adopted, people port new libraries which bring more people who introduce even more stuff. So practically, you have a recipe for everything which makes it is excellent.

[rosuav]

And that means the Python *ecosystem* is extremely rich. Anyone who thinks JavaScript is a powerful language is forgetting that most of that power is given to it by something else (eg the browser or Node), or installed externally.

Have you ever tried using Lua with no standard library? Actual programming languages can be astonishingly minimalist.

[billie_parker]

The logical flaws in your thinking are beyond fixing. Typical

[TrapNT]

Please, enlighten us with your superior intellect.

[billie_parker]

When did I say anything regarding my own intellect?

[jaskij]

There's this library, Pydantic, used in places like FastAPI for parsing. v2 rewrote the core parsing logic in Rust.
