Those are bridges to native CPython. There is also GraalPy (https://github.com/oracle/graalpython https://github.com/oracle/graalpython), which is a standalone implementation more similar to Jython. It seems already quite compatible with Python 3. I have tested the latest version graalpy-community-23.1.2 as a regular Python interpreter from the command line (i.e., not through a Java program). It was able to run my standard library-only Python scripts, as well as a script that made async HTTP requests with the external library HTTPX. It couldn't run a TUI program that used the Python Prompt Toolkit (`AttributeError: module 'signal' has no attribute 'siginterrupt'`). I am curious about your experience if you have used GraalPy more than I have.
