However most people would also expect 0.1+0.2==0.3 to return true, so what do I know. Floating point is something most of us ignore until it bites us in the ass. And then we never trust it again.

Mind u i find its often fine as long as my ide and chagpt know what type it is im usually fine. I do kinda like the rigidity of types tho. Proper Python type hints are a godsend.
