Anything complex should be written in a competent language like Java. Script languages (like Bash and Python) are for short (a few lines long) scripts. Using the tool outside the scope of what it was designed for is not a good idea.
I mean, viewing Python strictly as a scripting language? I am honestly lost for words. There are many huge and major applications and web sites written in Python, without people regretting it after the fact. And yet here you are dismissing it out of hand without a single argument.

Yeah, I have these same response patterns. Shell works really well for some use cases. I generally don’t respond to the comments that list the various “footguns” of shell, or that complain about security holes, etc. My use cases are not sensitive to these concerns, and even besides this, I find the concerns overstated.
But Python is not designed to only be a scripting language:
> What is Python?
> Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. It supports multiple programming paradigms beyond object-oriented programming, such as procedural and functional programming. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Finally, Python is portable: it runs on many Unix variants including Linux and macOS, and on Windows.
That said, Sonnet 3.5 had gotten me much further in bash than was possible before - and it's all really maintainable too. I highly suggest consulting with Sonnet on your longer scripts, even just asking it "what would you suggest to improve".
