Python is just a pile of dicts/hashtables under the hood. Even the basic int type is actually a dict of method names:

x = 1
print(dir(x))
['__abs__', '__add__', '__and__', '__bool__', '__ceil__', '__class__', '__delattr__', '__dir__', ... ]

PS: I will never get away from the fact that user-space memory addresses are also basically keys into the page table, so it is hashtables all the way down - you cannot escape them.

js is similar, though it does not include python's precalculated numbers
calculates integers from -5 to 256, see:

> a = 100
> b = 100
> c = 1000
> d = 1000
> a is b
True
> c is d
False

audible C++ programmer disgust

This is why I decided to learn Nix. I built dev environment flakes that provision the devshell for any language I intend to use. I actually won’t even bother unless I can get something working reliably with Nix. ;)

For example, here’s a flake that I use for my Python dev environment to provide all needed wiring and setup for an interactive Python web scraper I built:


{
  description = "Interactive Web Scraper";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs?ref=nixpkgs-unstable";
    utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, utils }: utils.lib.eachSystem ["x86_64-linux"] (system: let
    pkgs = import nixpkgs { system = system; };
  in rec {
    packages = {
      pyinputplus = pkgs.python3Packages.buildPythonPackage rec {
        pname = "pyinputplus";
        version = "0.2.12";
        src = pkgs.fetchPypi {
          inherit pname version;
          sha256 = "sha256-YOUR_SHA256_HASH_HERE";
        };
      };

      pythonEnv =
        pkgs.python3.withPackages (ps: with ps; [ webdriver-manager openpyxl pandas requests beautifulsoup4 websocket-client selenium packages.pyinputplus ]);
    };

    devShell = pkgs.mkShell {
      buildInputs = [
        pkgs.chromium
        pkgs.undetected-chromedriver
        packages.pythonEnv
      ];

      shellHook = ''
        export PATH=${pkgs.chromium}/bin:${pkgs.undetected-chromedriver}/bin:$PATH
      '';
    };
  });
}

I've been intrigued by Nix for quite a while. I will learn it as well.

It feels like magic. I think of it as the glue that makes almost all of my software work together seamlessly. I can’t wait to use it for one-click deployments of my software on a server or high-availability cluster.

Man, the variable scoping thing is insidious. It will never not be weird to me that ifs and loops don't actually create a new scope.

And then you try to do a closure and it tells you you didn't import anything yet.

Good meme. However I do think that most people starting out will not really have to deal with any of those issues in the first few years apart from maybe the pip/venv/poetry/etc choice. But whatever they'll pick it'll probably work well enough for whatever they're doing. When I started out I didn't use any external libraries apart from pygame (which probably came pre-installed). I programmed in the IDLE editor that came with Python. I have no idea how I functioned that way, but I learnt a lot and hat plenty of fun.

I think experienced programmers may have a different route to a degree. A number of years in one language, for instance, including fairly complex production settings, etc. and having to transition to python for a new job or company or decision from someone higher up the food chain. I did it from a largely perl and PHP background for both Rust (a tiny bit of experience before, but not a super complex environment) and Go (zero to prod in a few months dropping in rewritten portions of the former PHP monolith). I can talk about memory usage, race conditions, etc. but would be completely screwed with anything internal to python or its quirks.

What about the issue where people try to install new version of python sometimes try to uninstall the "old" pre-installed version on a linux system and thus borking the whole s

Definitely not me, anymore

[–] [email protected] 7 points 1 month ago

I may or may not have done this haha. I'm a threat to any working piece of software, just enough knowledge to be able to break shit and too little knowledge to avoid breaking shit. I think after all these years I've mostly learnt my lesson though. The package manager is the boss, and if I don't like it I have to work around it without upsetting the package manager

This a much better done meme

The other one before makes zero sense

I find Python easy to just code a prototype with. But I find Rust easier to get right.

[–] [email protected] 5 points 1 month ago

This is basically what I’ve been telling people for years. Prototype in Python to get the concepts down, then when you’re serious about the project, write it in a serious language.
