Graal Python - GraalVM Community Edition 1.0 RC6

Graal.Python is a Python 3 implementation for GraalVM. Currently, it is in the early stages of development and as such, it is not ready for any serious applications beyond simple use cases and scripting.

The Python language components can be installed in GraalVM using the gu utility.

More information is available on the GraalVM website: http://www.graalvm.org/docs/reference-manual/languages/python/

Changes since RC5:

• Support regular expression patterns built from bytes by using CPython's sre module as a fallback engine to our own
• Support LLVM 5+ for C extension modules
• Introduce native sequence storage so that e.g. Python bytes exposed to C can be mutated
• Introduce lazy string concatenation to significantly speed up benchmarks where strings are concatenated repeatedly
• C-API improvements to support more scikit-learn code
• Fix our distinction between builtin functions, functions, and methods to make the classes for builtin functions equivalent to CPython
• Improve set, frozenset, and dict support
• Attach Python exceptions as cause to ImportErrors raised for C extension modules
• Update standard library to CPython 3.6.5
• Support more code object attributes
• Support constant type ids for objects that are interned on CPython
• Add collections.deque
• Document how to contribute
• Improve efficiency of generators
• Enable re-use of ASTs in multiple Contexts in the same Engine
