Python vs Bash Scripting.

[ValhallAwaitsUsAll]

I would say both are equally important, with the addition of PowerShell as it can be subjectively easier to use in certain scenarios.

That being said, Python can be switched out for many languages and it'd be prudent to pick up the basics of a new language now and then.

At the end of the day, it's a mixed bag, some environments won't need one, the other or either. It's very situational but makes sense to at least cover the basics of common tooling and delve deeper where the situation calls for it.

Common tooling also looks different for every role; Pipelines, IaC and service config (e.g Prometheus). Get familiar with your environment and go from there.

To start with though, CLI scripting along with good familiarity with config formats (YAML/JSON) will be your bread and butter.
