    Python for the Java Platform

  • Quick note - CPython is the OG and most popular implementation of Python, but it is not the only implementation of Python. Some other fairly well-known examples are Jython (Java implementation), RustPython (Rust implementation), or the more mind-bending PyPy (Python implemented via Python 🤯). Python is an interpreted language, and you can think of all these different Python implementations as being different implementations of the interpreter itself. The interpreter is the program that takes your Python code and executes it via a virtual machine. This differs from a compiled language (like C) which needs the high-level C code to first be converted to machine code and then executed by the CPU.
