I would actually pick Go. Yes, the strong static typing is a pain in the ass, but the rules are simple and regular. It's easy to understand and implement.
The same cannot be said for the multitude of changes to Python.
I use/used Go for a while, but early on I thought the type system was stronger than it was. I was disappointed in a later project, and started looking at languages with stronger type systems.
I came across Haskell and Hindley Milner ;)
I believe Haskell replaces Go for me and with some experience (when I can picture types in my head better) it will replace python as my go to dynamic language.
