Python 3.11 - Hackdot

Re:Python 3.11 by salex89 on Monday October 04, 2021 @02:36AM (#28743743)

Wouldn't say it better myself. Everything you gain with fast coding you lose on tackling performance issues, GIL, dependency management... Things harder to solve once you're committed to production.

It depends very much on what you are doing. Python for big complicated applications is a No for me also but python for extraction jobs in a ETL pipeline or data science tasks is a huge YES.

I don't know; I've just written something in .net/c# and it's pretty bloddy difficult to deploy.

.NET can export self-contained single-file executable that doesn't require any runtime on the target computer/server.

Python has solutions like PyInstaller, but it's not built-in and requires building on the same system. In .NET, you can use the built-in tools to export binaries for Linux from Windows.

Except when you have some specific dependencies/targets that make this difficult. I'm sure I'll get there eventually, but I chose .net for this thinking it would be dead simple, and yet here I am wading through documentation and stackoverflow posts to get to my self-contained single-file executable.

Most windows users have at least 4/5 versions of linux installed on their machine so it's a non issue. They have wsl, a base installed partition, vagrant, a VM and probably docker containers. so running one extra command to gen a windows package isn't a big deal.

.net/C# was one of the easiest to deploy in my experience. Just build a self-contained executable and you're done.

Can you be more specific about your claims? What is wrong with Python?

> more complicated than any other programming language ever conceived of

is definitely untrue. Even if you take only mainstream languages then there are many more annoying to deploy, ones that are more complicated and so on.

Dependency management in python is much worse than most mainstream languages.

It was far easier for me to grok monads in Haskell (and it took less time), than to learn how to properly deploy a Python application. Given that monads are often a complaint and testament to the "complexity" of Haskell, I think it's unfair to make the claim that Python is uncomplicated. If you use a language for some period of time, it is very likely that you will have to deal with the tooling at some point.

Re:Python 3.11 by eesmith on Monday October 04, 2021 @04:31AM (#28744404)

I think the "it's" in "it's more complicated" refers to deploying software, not the language itself nor its support packages.

Re:Python 3.11 by globular-toast on Monday October 04, 2021 @04:31AM (#28744405)

When you say "deploy" do you mean "put it on a webserver"? I've deployed python Web services on to very limited environments that have nothing more than an interpreter. Nowadays I use pip-tools and docker which makes updating trivial.

Do you perhaps mean distribution as an app? I've had luck with pyinstaller. There can be fiddly bits but overall it's pretty smooth. It's easier if you are targeting a system with an interpreter, like a Linux distro.

Overall I just think you need to know what you're doing. I don't really think this is a bad thing. Maybe you could elaborate on what your difficulties are? From here I just don't see how it's more difficult than anything else.

Re:Python 3.11 by pansa2 on Monday October 04, 2021 @04:28AM (#28744385)

Yes - this is the reason I've switched to Go for writing command-line apps. I don't like Go as much as Python (Go is simpler, but not as easy), but being able to compile a self-contained executable is huge. It's also great to have access to GIL-free parallelism.

I don't expect Python to support either of those things any time soon.

This is a solved problem. The community provides a handy system overview[^1] that should be good enough for most cases.

It’s been like this for over a decade. I wouldn’t hold my breath. By comparison, I’m pretty sure the Ruby community adopted bundler over a decade ago.

Some of these approaches work for Windows, others for Mac, some for Linux, depending on versions of Python that are installed, etc. You can get around some of the problems with pyenv and a bunch of other tools.

Re:Python 3.11 by ido on Monday October 04, 2021 @03:50AM (#28744188)

I was originally using python (learned it in my first job back in 2001!) & that was the reason I eventually moved to other languages - python as a language is great but the tooling/ecosystem isn't for exactly these issues (or at least weren't at the time, that's also at least a decade+ ago by now).

My impression at the time was that using it for server side stuff was fine (i have control of the server and simply install all the right things/versions myself) but packaging it up for end users to install on their desktops/mobile was a huge pain, there was no real easy/simple way to just export a self running installer that you double click (on windows/mac) or an IPA/APK (on ios/android) and end up with a running program the way users were used to from e.g. a bundled .net (at the time using mono, now ms provides cross platforms .net implementations themselves) or native c/c++ executable.

I recently wrote a python script to handle serial communication and uploading of a bare metal binary to my RPi3, this saves me so much time debugging now that I don't need to swap SD cards continually. Excellent tool.

Re:Python 3.11 by dagw on Monday October 04, 2021 @02:32AM (#28743709)

Because of having to know what WSGI and ASGI are and picking the right one. Then pick which implementation of the above you want to use. Then configuring it correctly for your app. And finally make it play nicely with nginx/apache/whatever.

If on the other hand you're trying to deploy a desktop app, that is an entirely different kettle of 'fun'.

None if the Python in I deploy has to deal with any of that, all of which applies in a very narrow particular application domain. Even if it was a source of valid criticism, it would only be of using Python for that specific use, not generally.

<dream> There is a very fast Gunicorn replacement in Rust that accepts an wsgi/asgi module and a static dir and starts serving both. It breaks performance barriers for pure Python servers. It can automagically create systemd service and nginx site or just exist as a Docker entry point.

This comment is deceptive. This is a solved problem with virtualenvs. It is why Piku (https://github.com/piku) can deploy isolated apps with ease (and actually devotes less than 80 lines of code to the actual Python deployment).

It’s not a product. It’s an example of why it isn’t a problem, and it was actually _designed_ around virtualenvs, which is why it’s just a single script (again, not a product).
