Is there a way to interop Python <--> Kotlin

Maybe via C and Kotlin Native?

In JVM, you have Jython (though it only supports Python 2.7), and Graal, both of which are Java implementations of the Python engine which interpret and run Python code at runtime in the JVM and can interop with Java (or Kotlin/JVM) objects

@Anil Kumar: what's your use case?

I have a business logic which is shared across Android app, iOS app and website which is backed by a Flask (Python) server. Would be great if python interp could work in this case.

IMO, the least painful approach is interacting via a Flask API. Native interop is possible, but far more painful and error-prone.

It depends how soon you want it. See #python and #python-contributors, however that is a very, very early proof of concept. It is really interesting to follow, though.
