As a quick status update from my end, I've been working on a KSP processor and Gradle plugin for KNative interop with the CPython API over here: https://github.com/Martmists-GH/kpy-plugin This is different from the kotlin-python project, which aims to implement a python target similar to Kotlin/JS While it still has some small problems, it seems to mostly be functioning correctly, so if anyone wants to try it out here it is.

looks interesting! could you provide some minimal "hello world" example?

Assuming you've set up the project as shown in the readme:

package somemodule

@PyExport
fun hello(target: String) {
    println("Hello, $target!")
}

then simply run

pip install .

in the root to install from setup.py, and then

>>> import somemodule
>>> somemodule.hello("world")
Hello, world!

should work. Most of the things you can do are shown in the kpy-sample directory (though not using the gradle plugin as gradle doesn't like having a sibling project as plugin) Some things that I haven't fully worked out yet include registering custom type conversions, for example to only convert from/to numpy arrays. For now, only simple types and user-defined pyexports are able to be converted.

impressive (didn't try it out yet)! it's funny how the announcement of your project aligns with pausing of Python backend development. Fingers crossed that it will become usable one day 🙂
