GraalPython

GraalPython is an implementation of the Python programming language built on top of the GraalVM. GraalVM is a high-performance, polyglot virtual machine that supports multiple programming languages, including Java, JavaScript, and Python. GraalPython aims to provide a high-performance Python execution environment by leveraging the advanced optimizations and features of GraalVM.

The primary goal of GraalPython is to offer significant performance improvements over standard CPython implementations for certain types of Python workloads. This is achieved through GraalVM's Just-In-Time (JIT) compilation capabilities, which can optimize Python code at runtime. GraalPython also supports interoperability with other languages running on GraalVM, allowing for seamless integration between Python code and, for example, Java libraries.

GraalPython is developed as part of the GraalVM project. It aims to be largely compatible with standard Python, allowing most existing Python code to run without modification. However, due to its different execution model and reliance on GraalVM, some edge cases or specific C extensions might behave differently. The project is an ongoing effort to push the boundaries of Python performance and interoperability within a unified virtual machine environment.
