Reading this got me thinking and I wonder if other people feel like me about this, so I'm going to share it. This is not serious, but not entirely unserious... I try to be a good sport about it, but every time I write python I want to quit software engineering. It makes me angry how little it values my time. It does little for my soured disposition that folks then vehemently lecture me about the hours saved by future…
It seems to value my time quite highly, as I can achieve most things more quickly and easily in Python than any other language I know. Can you be more specific about how it increases your burnout? Is it the language, or someone forcing you to use that linter and settings?
I believe Python is quite possibly the best language for a few things
* Exploratory programming - such as what data scientists do
* Writing programs that will never grow beyond 150LOC, or roughly what fits on a screen + one page down
When I have those two constraints met I am almost always choosing Python.
Here are some problems I face on codebases as they scale up:
* Python conventions lead to what I consider bad code. Devs will often choose things like 'patch' over dependency injection, and I have seen on multiple occasions projects derided for providing DI based interfaces - "oh, why would you write code that looks like Java? This is Python".
There's a lot of death by a thousand cuts. Keyword args in functions are abused a lot, because they're "easy", ability to patch at runtime means it's often "easy" to just write what looks like a simple interface, but it's then harder to test. Inheritance is "easy" and often leads to complex code where behaviors are very, very non-local.
Dynamic types mean that people are often a little too clever with their data. I've seen APIs that return effectively `Union[NoneType, Item, List[Item]]` for absolutely no semantic reason, without type annotations, meaning that if you assumed a list or none came back you were missing the single Item case. The implementation actually internally always got a list back from the underlying query but decided to special case the single item case... why? I see this sort of thing a bit, and other languages punish you for it (by forcing you to express the more complex type).
* I find myself more and more leveraging threads these days. I did this often with C++, and all the time in my Rust code. Python punishes you for threading. The GIL makes things feel atomic when they aren't, reduces you to concurrency, all while paying the cost of an OS thread. Threading primitives are also quite weak, imo, and multiprocessing is a dead end.
And, really, Python is anti-optimization, which is a good and bad thing, but it's a bit extreme.
* Implicit exceptions everywhere. I see 'raise Exception' defensively placed in every Python codebase because you never know when a piece of code will fail. I see a lot of reliance on 'retry decorators' that just catch everything because you never know if an error is transient or persistent.
The common "don't use exceptions for control flow" is broken right off the bat with StopIteration. I just think error handling in Python is god awful, really.
* Mypy is awesome, but feels like a bit of a hack. The type system is great, and in theory it would solve many problems, but coverage is quite awful in open source projects and the type errors I get are useless. I actually only use mypy to make my IDE behave, I don't run it myself, because my types are actually technically unsound and the errors are too painful to work with (and honestly the type system is quite complex and hard to work with, not to mention the bugs).
There are lots of other smaller issues, such as my distaste for pip, py2/3 breakage, lack of RAII, the insane reliance on C all over the place, I think syntax is bad in a lot of places (lambdas, whitespace in general), etc but these are probably my main sticking points with using the language for large projects.
Again, Python is actually my favorite language for specific tasks, but I really think it's best optimized for small codebases.
