It's such a shame python got such mindshare. It's a disaster of a language and ecosystem that people keep bolting and hacking things that much better thought out languages have had for decades.

At this point, Python is less of a programming language by itself but more of an interop protocol between various C/C++/Fortran/Rust binaries. But again, it's just part of the cycle, Python was a breath of fresh air 10 years ago when academia is still dominated by Matlab, but now it is mostly a mess of a language that's good for throwaway scripts but not very convenient for large software projects compared to statically typed languages.

I remember falling in love with Python when I first learned it at version 1.5, liked it even more with 2.0, but when 3.0 came around, that's when I noticed the ecosystem falling apart. Not for the obvious incompatibility schism: I do think most of 3.0's changes were good ones, and it finally is the standard default version now, but in many other ways it feels like the ecosystem has still never really recovered. Virtualenv is still the same grotesque hack, where rather than doing what other languages like Perl and Ruby do and making some wrapper around setting PYTHONPATH, it relies on python's behavior of locating the library path relative to the install, thus hardlinking a whole python installation in and making you "activate" it first. That nothing has managed to replace it in 20 years speaks volumes.

  • I'm hoping one day people look at Python the same way they look at Perl and PHP.

    There has been so much programming language innovation in the past decade that I'm surprised someone hasn't built a better Python. I'd like to see something like Rhai or Roto take off which has a natural upgrade path to Rust.

    Maybe it's because interpreted languages just aren't in vogue anymore and probably won't be for a long time if humans aren't even coding anymore.

    • > I'm surprised someone hasn't built a better Python.

      I believe Mojo is an attempt at that. Python is probably too entrenched by my estimation.

  • Roughly the time when Guido stopped fighting the hordes. The hordes won, wrested the language away from its creator and now they own the pieces. 2 to 3 was the worst possible way a language has ever been upgraded bar none. Hilariously, even today Python 2 persists in many places because of this.

  • > thus hardlinking a whole python installation in and making you "activate" it first

    You don't have to activate a venv to use it; `$VENV_PATH/bin/python3` just works.

    (It also softlinks/symlinks the binaries.)

I work in python daily, it's not necessarily my favourite language, but I'd say it's mostly fine.

What languages are you thinking of specifically when you mention better thought out ones?

  • Pretty much every other mainstream language bar JS. I'd say also Ruby because I also do not like a lot of its choices, but there's at least a kind of heady elegance to it in a REPL, though I would never want to work on a production system written in Ruby.

    Frankly, I just really prefer statically and strongly typed compiled languages.

    I did my last company's first Demo and MVP in Python after running through the Koans at my co-founder's behest and ultimately we decided that the production system would not be done in Python. There are some cool things about it - specifically I do like that annotations are real AOP seams, but the numerous footguns and lack of types and a compiler just make it a very annoying ecosystem to work in for me.

  • They are a heavy C# user. Coke/Pepsi situation.

    • I don't agree at all that it's a coke/pepsi situation. That analogy is for when two mostly-interchangeable choices develop tribal followings based largely on personal preference. Coke and Pepsi are both caramel carbonated soft drinks that are terrible for your health differing only slightly in flavour. Otherwise they're materially identical.

      C# is strongly/statically typed, compiled, and quite fast (after the vm has started), whereas python is weakly/dynamically typed, interpreted, and generally slow as fuck. Those are two fundamentally different languages, how could it possibly be a coke/pepsi situation?

      I think python is fantastic for certain use cases: gluing other tools together (like LAPACK or other ancient libraries), system automation, prototyping, exploitation (I think pretty much all of us were working on stealmybitcoin in python), and exploratory data analysis.

      The problems arise when people try to write, say, gigantic GUI applications in python, or really anything with CPU-bound workloads. Part of being an engineer is using the right tool for the right job. Python is the wrong tool for lots of jobs. That shouldn't be a controversial statement.

And the thing that maddens me the most is that it has a critical mass where it’s basically the default starting language and most people never really move from there. And so we’re stuck with this grotesque abomination that somehow keeps on rolling. The amount of money that was poured into python to make it barely bearable is probably the GDP of a small nation.

I’m not a fan either, but it doesn’t bother me at all. Who cares? Let the python people do their thing.

Fascinating take.

What do you attribute Python's success to, in spite of being a disaster of a language and ecosystem?

  • 20 years working on Python. Two things have driven its success.

    First, it's easy to learn and reasonably powerful. You can make a lot of useful things really quickly, which was true even 15 years ago. It's only gotten easier since, and the ecosystem has continued to grow.

    Second, ML latched onto it. That gave Python a lot of credibility for people coming through CS programs and into industry, especially as AI use cases were picking up momentum. Think Tensorflow starting 10-ish years ago, then Pytorch, and so on.

    [opinion time] Unfortunately, ML has contributed to disaster. The quality of software engineering in ML applications lags badly behind that in other segments, and there's where most Python development is happening now. The feedback loop of training Bad Python into LLMs is only making it worse. The skill floor was dropping, and now it's practically zero.

    It also wasn't helped much by language design decisions. Gradual typing was a huge mistake. It would have been much better to go the Typescript route and define a superset of the language that compiles to native Python. The grafted-in typing features that rely on runtime behavior and never got an actual spec for a type system haven't helped.

  • It's incredibly easy for new engineers to pick up. On the spectrum between "features easy for beginners but nightmarish for experienced engineers" and "features complex for beginners but great for experienced engineers" it always makes the tradeoff for the former.

  • Probably the batteries included Standard Library.

    Cross platform interpreter.

    NumPy and SciPy really set the stage.

    • It's definitely a better language than Matlab, and Numpy made it actually fast for that purpose. AI research really took advantage of that even before LLMs hit the scene.

  • I'm not the OP, but it seemed to me that major teaching institutions settled on Python as a pedagogic language after previously having rallied around Java for same, and various other languages before that.

  • BASIC rebooted. Right at the right time too, BASIC was never going to thrive in the days of the internet.

    I'll give Python one thing though, it is by far the most elegant way to glue together a large number of otherwise incompatible C libraries.

  • They provide binaries for almost every open source library for every popular platform. If you need something, whatever it is, python was and is probably the easiest way to install and use it.

  • It was the first language that actually felt ready-to-use, available for free-as-in-speech. Batteries included, robust online development community, sensible featureset, main libs that were designed bottom-up instead of top-down. I remember learning Java 1.2 or 1.4 after learning Python and it felt like a huge regression. Swing was a joke compared to TkInter (which was weak compared to proper GUI editors like VB but at least made nice scalable native-feeling GUIs and had a sensible API) and the standard collections were miserable without generics.

    But Python peaked like 20 years ago. The later features were too ugly, and it was too slow to fill the obvious gaps in the language.

  • Marketing in academia, decent C-API that led to use in scientific Python.

    The language is a disaster since it deviated from its original purpose. The community is ruled by insane, mediocre narcissists who drove away all reasonable people.

  • - Math + visualization libraries (which ironically have to break out of Python to do their job)

    - Reasonable ergonomics for describing data flows, as long as you never run the code, which you often don't care about if you're a mathematician

    - Adoption by people who optimize pumping citations, not reproducible results -- non-working code is a feature when you're trying to BS

I've been thinking recently, there's hardly any reason not to use a native language like Rust anymore. The classic reasoning for languages like Python is that it prioritizes developer time and resources over compute resources, but now developer time is rapidly trending to zero and everything is compute dominated.

  • Not having to build still saves wall clock time. Also Python is a concise language (fewer tokens in context) with a monster ecosystem that avoids a lot of code having to written by agents (fewer tokens for the current task and fewer for future tasks by keeping the code base smaller).

    • Most of that monster ecosystem is exactly that: monstrous code in one-off throwaway libraries written by people who don't care about software, as it's not their job.

      If you set a bar, any bar, there's really not much offered by Python that you cannot find in a more reasonable language. Especially if you're gluing together C++ and Rust libraries for data processing or ML workloads. Python is still disproportionately popular there but I'm also convinced its days are counted. C++ will be tremendously harder to get rid of, in comparison, if that's even possible.

  • Rust has Rhai and Roto too if you need better than Python level of developer considerations.

Unpopular take, but:

I work in python. It's only real and big issue is the slow interpreter. Everything else is resolvable one way or another. The only other big issue it has is the envy of people who imagine that if not for python, their beloved language would be as used as python is now. Most of their beloved languages are older than python or when they were created, they had much bigger ticket backing than python and those languages are still not where python is. The reason? Python is made to solve the issue one has now, not the issue one might have in the future. Local optimum at its best and worst. And honestly, most people have the current issue to solve and rarely reach the imaginary issue to be. If python didn't exist, it would have been invented.

  • The issue is that it just becomes a “bad at everything” tarpit.

    - performance is awful.

    - gradual typing is sort of ok, but relies too much on runtime behaviour.

    - async support is a bit all over the place.

    - uv has made the packaging experience sort of liveable, but collectively it’s still very limited: feature support, conditional dependencies, rudimentary tree shaking, cargo-style workspaces, etc.

    In an era where your options of tech stack are freer than ever, unless you explicitly need PyTorch, I’m not really sure why you’d choose Python over literally everything else.

I will take Python over typescript every second of every day. TypeScript is just so unreadable compared to Python.

As a Ruby dev I'm kind of primed to hate on Python a little bit, but I have to agree. I've written some Python over the years, I've tried to like it, but it just doesn't feel good to me. There are things that are really great about Rust, Elixir, C#, Swift, Java, Common Lisp... Sometimes it's the standard library, sometimes the package manager, sometimes a feature (borrow checker, pattern matching), sometimes a principle (everything is an object, the code is just data). In Python, everything is kind of meh. Like they came up with the list comprehension syntax and that was it for cool things.

  • List comprehensions? Really? I remember when they were pretty and I was learning them alongside other languages with higher order functions and Python's approach seemed to be the ugliest of its cohort. They were neither as logical as simple Lispy "take a function as a parameter" things like Ruby, nor were they the kind of clean and legible stuff we expect from Python.

    • I'm not saying I personally like them, but they're not as bland as the rest of the language. FWIW, I watched 3 non-dev people around me learn Python in uni (biologist, lawyer, graphics designer) and they all liked the list comprehension syntax.

The packaging is a nightmare thats for sure.

Venvs, activate, deactivate, shitty scripts hacking on $PATH. How did this ever ship? Then there was poetry, `uv`, and maybe something in else in $CURRENT_YEAR.

Try to set it up on a new macOS, go on. Install a package from pip, and there's a bunch of garbage that won't let you do it.

It's horrible. Python packaging engineer is now an FTE, maybe that's what they wanted.

  • The fact that they didn't solve Venv when they did the breaking change in Python 3 is absolutely bonkers.

Python had no corporate backing, no marketing, it became popular because people actually like to use it. Sorry you've only been using "better thought out languages" instead.

Python should have done runtime type checking instead of compile-time only String and List annotations and so on

Worse is better. Avoid using it yourself and tell others; that's the best you can do.

Python is pretty decent. What are you talking about?

  • The syntax and meaningful spaces are annoying. The dynamic typing is abused to hell in everything including the standard library. It has wacky paradigms like "exceptions instead of conditionals" or having "else" clause for loops.

    It lacks decent packaging and by design cannot handle multiple versions of dependencies or perform metadata-only/declarative resolution. To resolve the dependencies of a Python package you need to install it. Many Python packages resolve their dependencies imperatively depending on the current system state. When you need binary dependencies like numpy it gets even worse since libpython doesn't have a stable ABI.

    It is one of the most underdesigned languages but it holds a dear place due to being easier to translate from pseudocode to actual implementation. This resulted many academics to pick it up and write advanced math libraries in it.
