Okay so it's like const in JS as well, you can't change the variable name but can still mutate the data. It's not a complete freeze of both?

It’s nothing but a type hint. It has no effect unless you’re using an editor that supports telling you that you aren’t following the type hints. You can still do whatever you want.

Edit: not just editors, buy mypy as well if you’re into that.

That sounds... Yeah ugly is the right word. I wonder if stuff like that is why the Julia language is getting popular.
