copied!<p>Besides Pyrex/Cython, already mentioned, you have other alternatives:</p> <p><a href="http://code.google.com/p/shedskin/" rel="nofollow">Shed Skin</a>: Translates (a restricted subset of) Python to C++. Can automatically generate an extension for you. You'd create an extension doing this (assuming Linux):</p> <pre><code>wget http://shedskin.googlecode.com/files/shedskin-0.7.tgz tar -xzf shedskin-0.7.tgz # On your code folder: PYTHONPATH=/path/to/shedskin-0.7 python shedskin -e yourmodule.py # The above generates a Makefile and a yourmodule.h/.cpp pair make # Now you can "import yourmodule" from Python and check it's from the .so by "print yourmodule.__file__ </code></pre> <p><a href="http://pypy.org/" rel="nofollow">PyPy</a>: A faster Python, with a JIT compiler. You could simply run your code on it instead of CPython. Only supports Python 2.5 now, 2.7 support soon. Can give huge speedups on math-heavy code. To install and run it (assuming Linux 32-bit):</p> <pre><code>wget http://pypy.org/download/pypy-1.4.1-linux.tar.bz2 tar -xjf pypy-1.4.1-linux.tar.bz2 sudo ln -s /path/to/pypy-1.4.1-linux/bin/pypy /usr/local/bin # Then, instead of "python yourprogram.py" you'll just run "pypy yourprogram.py" </code></pre> <p><a href="http://www.scipy.org/Weave" rel="nofollow">Weave</a>: Allows you to <a href="http://dpinte.wordpress.com/2010/04/22/interfacing-gsl-with-python-using-cython-comparison-with-weave/" rel="nofollow">write C inline</a>, the compiles it.</p> <p>Edit: If you want us to run these tools for you and benchmark, just post your code ;)</p>
