With shell, I can take the same tools I’ve already been using as one-liners while fiddling around, and reuse them. There is no syntax mapping to do in my head.

With any other language, I have to map the steps, and probably also add various modules (likely within stdlib, but still). That’s not nothing.

I’ve rewritten a somewhat-complicated bash script into Python. It takes some time, especially when you want to add tests.
