Have you considered GraalVM? You can run both languages inside the same managed runtime (JVM), sharing the same data structures, inlining across language boundaries, and debug both with Chrome Dev Tools.
Generally if you want python/java interaction, we maintain a tool called javacpp that handles this, we even bundle cpython: https://github.com/bytedeco/javacpp-presets
GraalVM itself also depends on javacpp for a portion of its features (LLVM wrapper): https://github.com/oracle/graal/blob/315f5dcf69c2e73fd13a5f8...
I'd be happy to answer questions about the overlap of the 2. I can say I happily execute python scripts from our embedded python and even point the python execution at an anaconda distribution.
I remember coming across GraalVM. However, as I solo developer, I have found learning another new thing to be detrimental to my ability to getting things done. I have wasted way too many hours learning new frameworks, languages, platforms, etc.
I'm doing my best to avoid learning something new except when a strong compatibility with my current stack exists and is quickly implementable.
