Python is the second best language for everything. Having one language that does it all is better than learning several that might do it a little bit better.

Careful, that attitude is how we ended up with this infestation of JavaScript!
- grue ( @grue@lemmy.ml ) 5•1 year ago
JavaScript is very much not the second best language for anything.
JavaScript came about because it was the only choice in the context for which it was designed, and then it metasticized into other contexts because devs that used it got Stockholm syndrome.

Speed is a serious problem in Python though. Python has its use cases, and so do other languages. Things would not end well if we started using Python for everything.
- noli ( @noli@programming.dev ) 4•1 year ago
This might be an unpopular opinion but python’s speed wouldn’t even be an issue if it was 5x slower than it is now.
Python is a language designed for write-time performance, not runtime performance.
- Diplomjodler ( @Diplomjodler@feddit.de ) 3•1 year ago
If I wanted to write a 3D game engine, I wouldn’t use Python either. But there’s zero chance of me ever doing that. For 90% of things 90% of people do, Python works just fine. And the performance thing is actively being worked on and getting better all the time.
- entropicdrift ( @entropicdrift@lemmy.sdf.org ) 5•1 year ago
Python is the best “glue” language I’ve ever used. When you want to chain together your program’s high-level logic and all of the loops happen inside lower-level languages like Rust, Go, Zig, D or C, Python’s performance is perfectly adequate and it’s so clear and concise it reads like pseudocode.
- Diplomjodler ( @Diplomjodler@feddit.de ) 2•1 year ago
As long as you do all your lookups with dicts or sets performance is pretty decent for smaller workloads.
- grue ( @grue@lemmy.ml ) 1•1 year ago
Python is secretly a functional-paradigm language. If you’re not making liberal use of comprehensions instead of loops (especially loops with LBYL conditions in them), you’re doing it wrong.

I can’t think of a single reason to use bash over Python. Anything you can do in bash can be done in pure Python. Unless you’re working in some embedded environment it’s a non-issue to install a Python interpreter (you certainly already have one). I would only use sh/bash for packages I’m distributing to avoid the external dependency, and then only if it’s a relatively simple script.

Why is always about bash? POSIX shell scripts run everywhere.
- IRQBreaker ( @IRQBreaker@lemmy.kozow.com ) 2•1 year ago
Granted, it’s a kind of niche use case but in the embedded world there’s usually size constraints which prevents a full blown bash installation.
However, things are better now than 20 years ago. Flash is cheap.
- CoderKat ( @CoderKat@lemm.ee ) English6•1 year ago
Python is superior for string anything (parsing, searching, manipulating). But Bash is much simpler for running existing CLI tools. Plus you should already be using Bash as a simple terminal language already, so wrapping what you’re used to into a simple script flows naturally.
Eg, if I have some admin tool for updating a user thingamajig, a common scripting need is just running that tool for every user in a file (or the output of another command). The string manipulation that often requires is annoying in bash, but running the commands is easier than Python.
- Kogasa ( @kogasa@programming.dev ) 4•1 year ago
If what you’re doing is essentially a few shell commands, then you may as well put it into a script. If you’re talking about how “elegant” your shell scripts are and comparing them to Python, you’re probably wrong and should be using Python.

Things that could have been done in bash is python’s best usecase. And bash sucks for scripting. Why not python?
- entropicdrift ( @entropicdrift@lemmy.sdf.org ) English15•1 year ago
There are many cases where bash/shell is better than Python. For one, any time you’re just stringing together 2-4 existing shell tools, bash has unbeatable speed since it’s all running in C. Plus, you should probably learn the tools anyways to handle CLI stuff on a day-to-day level, so the knowledge is reusable and becomes very intuitive to compose into some crazy one-liner piped chains of commands. If I just want to loop over a set of directories and do a couple chained CLI commands on each directory, this is the way I go.
That said, in cases where you’re doing something very custom, any time you’re doing something that can’t be simply described as a chain of CLI tool transformations, and any time you want to maintain a global state across a complex set of operations outside of a pipeline, I agree that Python is generally a more robust solution with much easier maintainability.

If we’re talking about 5 like script, then sure. Just use bash. But python is much better long term, in my experience, for scripts any bigger than that.
- dukk ( @dukk@programming.dev ) 2•1 year ago
Not really true. Python was created for, and is still best used for data science. It’s user-friendliness made it a first for many inexperienced programmers too, and it started to be used for way more than it was initially intended. I’m not saying it’s bad at everything else, but there’s most certainly better tools for the job.
- pulaskiwasright ( @pulaskiwasright@lemmy.ml ) English4•1 year ago
I won’t argue with what it was created for, but I disagree that it’s best usecase isn’t as a bash replacement. That’s the only spot I’ve used and liked it.

- Reptorian ( @Reptorian@programming.dev ) 1•1 year ago
I know there’s a lot of downvotes because there are people reading this as hate toward Python. On one hand, one can make the case that it is overused and this doesn’t bold well for those that simply can never like it’s syntax. On the other hand, Python is perfect for small scripts that isn’t tailored for a Domain or just quick codes.
- sanosuke001 ( @sanosuke001@lemmynsfw.com ) English3•1 year ago
Honestly, I’m not really a fan of the formatting and syntax of Python but I agree, it is a fine choice for scripting things quickly if you don’t mind the language itself.
The biggest issue I have with it are all the incompatible versions, juggling modules, having some other random thing with a ridiculous configuration, where a bash script would be infinitely easier. Anything more complicated and Python is just too much of a headache.
