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.
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.
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.
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.
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.
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.
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.
MFW I'm using sh variant #7923 and trying to write a for loop.
On that other site, I compared it to being a lifelong English-speaking resident of Chicago and being unable to order a pizza in Indianapolis without a phrasebook.
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.
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.
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.
The only validation you should expect and need is self-validation.
Your work is absolutely valid and important. Your efforts are absolutely appreciated and worthwhile. But people are stuck in their own heads and work and stress and concerns and desires and validation loops and it takes actual work to break out of that to not only offer appreciation but to even realize that they need to offer it.
And for that reason, you should also really appreciate anyone that validates you.
