I'm going to preach the wonders of Python dataclasses, but for reasons of interested to those who have already gone down the delightful rabbit-hole of typed Python. So let me start with a quick plug for mypy if you haven't heard about it.

Learning Go has been a fun journey, and when you’re used to writing a mainstream language such as Java or C# the learning curve isn’t that steep. But there are some things I had to actively unlearn when learning Go. Most of the things here are not harmful to your code at all, and the code functions pretty much as intended anyway. The compiler will not come shouting at you, so perhaps the worst that could happen would be a nitpick comment on a code review. 😃
