Lmao, bruh. How do people keep praising a language where messing up a space breaks everything and there is no real type system?
The whitespace doesn't bother me. Any IDE worth a damn will manage that for you. As for the type system, yeah, I strongly prefer static typing, but for simpler projects I can see the convenience of it.
My real issue with Python comes with managing a development environment when multiple developers are working on it. Dependency management in Python is a headache, and while in theory, virtual envs should help with synchronizing environments from machine to machine, I still find it endlessly fiddly with a bunch of things that can go wrong that are hard to diagnose.
Python is great for small scripts, proofs-of-concept, and such, but I wouldn't write anything more heavy-duty than that in it.
You can totally write heavy duty things if you know what you're doing: use type hints, static checkers, tests, etc. It just takes a bit more effort and care.
Personally, my estimate doubles when we're asked to implement something in Python...
That's a proficiency matter. Python is the language I can get something done the fastest today, but 6 years ago that would be Java or even JS for me.
Yeah, working on python projects professionally is always a nightmare of configuring env variables and trying to get your system to perfectly match the reference dev system. I find Node.js projects to often be the simplest and most pain free to setup, but even compiled languages like C# and Java are often easier to get up and going than python.
Haha: "A space breaks everything." Fuck YES! Are you kidding me‽ It's one of the best features!
Why? Because it's so easy to see. In other languages you've got semicolons which are surprisingly difficult to notice when they're missing. Depending on the situation (or if you're just new to programming) you could spend a great deal of time troubleshooting your code only to find out that you're missing a semicolon. It's frustrating and it makes you feel stupid which is never a good thing for people who are new programming.
Types are in a different category altogether with seemingly infinite reasons why you'd want a feature-rich, low-level type system and also why you'd want to avoid that.
IMHO, the point of Python is to be a simple language that's quick to write yet also very powerful and speedy when you need it to be (by taking advantage of modules written in C or better, Rust). If it had a complex type system I think it would significantly lower the value of the language. Just like how when I see an entire code repo using Pydantic and type hints everywhere it makes the code unnecessarily complex (just use type hints where it matters 🙄).
I'm not saying using type hints on everything is a terrible thing... I just think it makes the code harder to read which, IMHO defeats the point of using Python and adds a TON of complexity to the language.
The promise of type hints is that they'll enable the interpreter to significantly speed up certain things and reduce memory utilization by orders of magnitude at some point in the future. When that happens I'll definitely be reevaluating the situation but right now there doesn't seem to be much point.
For reference, I've been coding in Python for about 18 years now and I've only ever encountered a bug (in production) that would've been prevented by type hints once. It was a long time ago, before I knew better and didn't write unit tests.
These days when I'm working on code that requires type hints (by policy; not actual necessity) it feels like doing situps. Like, do I really need to add a string type hint to a function called,
parse_log()? LOL!Exactly! I've wasted more time hunting missing semicolons in languages that use them, than fixing wrong indentation in Python.
It’s kinda funny that Godot’s custom language GDScript is, at least on a surface level, pythonic (no list comprehensions, context managers, decorators, etc, it’s mostly syntactical similarities). But type hints do make it run faster!
I was blessed to get to skip most of the old pains in python. I only had a handful of scripts that ever needed to be ported from 2 and they didn’t rely on any libraries. The ecosystem is easy to work with and I’m looking forward to working with Python for the foreseeable future
I don't mean this insultingly because lots of programming jobs don't require this and for the ones that do we still tend to all start here, but in all honesty this sounds like it's coming from someone who's never worked on a large project maintained by multiple people over time.
First of all, the hysteria over semicolons is ridiculous when JavaScript, Typescript, C#, Java, Go, Swift, etc. etc. wil all automatically highlight missing semicolons, if not automatically insert them for you when paired with an IDE and standard linter. On top of that, JavaScript and Typescript do not require semicolons at all, but they are still used alongside braces, because they make your code more scannable, readable, and moveable.
Secondly, without type safety your code is no longer predictable or maintainable. If you're working to quickly sketch out some new fangled logic for a research paper it's one thing, if you need to write test code so that your codebase can be tested an infinite number of times by other coders and whatever CI/ CD pipelines to make sure that nothing's broken, then all of the sudden you start seeing the value in strict typing.
Honestly, complaining about type safety adding "extra code" is a complaint that almost every coder has when they start out, before you eventually realize that all that "extra code" isn't just boiler plate for no reason but is adding specificity, predictability, reusability, and maintainability to your code base.
When defining types looked like this it was one thing:
String name = new String("Charles Xavier");But when it looks like this, there's no reason not to use strong typing:
const name = "Charles Xavier";Anyone who thinks a strong type system is a drawback has never worked on any real project where you actually have to collaborate with others.
Yeah, the alternative to static typing is to write tons of unit tests, which definitely adds a lot more code to your codebase.
This sounds like someone who's never worked on a large Python project with multiple developers. I've been doing this for almost two decades and we never encounter bugs because of mismatched types.
For reference, the most common bugs we encounter are related to exception handling. Either the code captured the exception and didn't do the right thing (whatever that is) in specific situations or it didn't capture the exception in the right place so it bubbles up waaaaay too high up the chain and we end up with super annoying troubleshooting where it's difficult to reproduce or difficult to track down.
Also, testing is completely orthogonal to types.
Have you worked on major projects in other languages in that time period to be able to compare and contrast?
The last two python projects I had to work on didn't have bugs because of type issues, but it was much harder to come into the codebase and understand what was going on given that you didn't have type information in many many places which forced you to go back and comb through the code instead.
What are you writing your code in? Windows notepad? How the hell do you not see the semicolon missing?
because semicolons are tiny characters that oftenhave to be appended to the end of lines (precisely the worst place for them to be easily visible, since they'll blend in with the previous character)
whitespace meanwhile is very easy to notice that it's missing, as i'm sure you noticed when reading the above sentence.
