Not at present, at least not reasonably. There are Python WinRT bindings under development (https://github.com/Microsoft/xlang/tree/master/src/package/pywinrt/projection https://github.com/Microsoft/xlang/tree/master/src/package/p...) but they don't (yet?) support the "composable types" type system feature (basically a form of implementation inheritance) that the WinUI and Composition types require. So you'd basically have to write your own support for this.
