For scripting and "just throwing something together for internal use," Python is a pretty traditional choice, but I think Go is able to outclass it for maintainability -- static typing and somewhat better package management are a big help, and Go has a comparable ecosystem.

If that was a useful argument for the future we'd all still be using Perl.

I mean, I still write a lot of Perl, but everyone else would be too.

Naive question, can't you just call Python code from Go? I don't see the problem besides that performance of the Python libs wouldn't be as good as if they were written in Go.
