I do a lot of sysadmin stuff & a lot of python stuff & bc I really like #python I want to tell you to "go out and learn it to make yourself a better sysadmin!!" but if you're already scripting w/bash/PowerShell, those tools are just fine (& often the most efficient) for #sysadmin work.
If you want to make your all-around IT skill set more dynamic, then learn python, which is worth the effort & might stir up ideas for more elegant solutions to problems you encounter

It depends on needs and availability. I love #Python but I am forced to use #ShellScripts because they are good enough 90+% of the time and because Python isn't installed on the Production instances I run.

it really depends on the context. Bash is basically universal, which is nice. But complex bash scripts are unmaintainable - the language simply isn't made for actual programming. There's a place for each of them, I think.

for me ut is complexity based; my maxim is “use the smallest tool that succinctly solves the problem “. So sed awk shell python. Ish. So when things become cumbersome in shell, use python. I have a lot of each, but the complex stuff is python.
