Is it possible to compile Python natively (beyond pyc byte code)?

Question

I wonder if it is possible to create an executable module from a Python script. I need to have the most performance and the flexibility of Python script, without needing to run

Answer 1

I think you can use jython to compile python to Java bytecode, and then compile that with GCJ.

Answer 2

I've had a lot of success using Cython, which is based on and extends pyrex:

Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language, but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code.

This makes Cython the ideal language for wrapping for external C libraries, and for fast C modules that speed up the execution of Python code.

Answer 3

You can use something like py2exe to compile your python script into an exe, or Freeze for a linux binary.

Answer 4

• There's pyrex that compiles python like source to python extension modules
• rpython which allows you to compile python with some restrictions to various backends like C, LLVM, .Net etc.
• There's also shed-skin which translates python to C++, but I can't say if it's any good.
• PyPy implements a JIT compiler which attempts to optimize runtime by translating pieces of what's running at runtime to machine code, if you write for the PyPy interpreter that might be a feasible path.
• The same author that is working on JIT in PyPy wrote psyco previously which optimizes python in the CPython interpreter.
