PyPy 2.0

PyPy 2.0 1.9 implements Python 2.7.2 and runs on Intel x86 (IA-32) and x86_64 platforms, with ARM and PPC being underway. It supports all of the core language, passing the Python test suite (with minor modifications that were already accepted in the main python in newer versions). It supports most of the commonly used Python standard library modules. For known differences with CPython, see our compatibility page. If you are interested in helping to move forward, see our howtohelp page. Speed Our main executable comes with a Just-in-Time compiler. It is really fast in running most benchmarks. Try it out! Sandboxing PyPy`s sandboxing is a working prototype for the idea of running untrusted user programs. Unlike other sandboxing approaches for Python, PyPy`s does not try to limit language features considered “unsafe”. Instead we replace all calls to external libraries (C or platform) with a stub that communicates with an external process handling the policy.
