pycontracts supports runtime type and bound checking on Python 2 & 3
There is a global toggle: https://andreacensi.github.io/contracts/overhead.html#overhead
Unfortunately, the type specifiers precede and are different (e.g lowercase) from those used for static analysis in mypy.
There are orobably additional differences? On Jul 8, 2016 11:04 AM, "David Mertz" email@example.com wrote:
I provided a decorator recipe to do just what Chris Angelico describes a year or two before PEP 484 described static typechecking. I think what I do is a consistent subset of PEP 484 still, modulo the difference between runtime and static.
It would be a lot more work to do everything the typing.py module and PEP 484 describes (algebraic typing, basically), but it's all just code that is compatible back to Python 3.0.

Anyway, I just throw an idea to here. Greet to all of you for bring Python to me.
Keep on throwing ideas this way! Ideas are great. Well-thought-out ideas make for interesting discussions, even if they don't get implemented. Often the answer ends up being "here's a way to do this with the current version", but it doesn't carry with it a tag of "and you're an idiot for even suggesting it". We like ideas here - otherwise we wouldn't subscribe to this list :)
Agreed! I'd have never even thought of Chris' decorator approach before this discussion occurred, so thanks for raising the subject. I may never use it, but knowing how to do something like this is great.
