If the bulk of your code is in Python, write an extension module in C++. You can use Swig or Boost here. If the bulk of your code is in C++, embed Python. The general rule is "extend, not embed" Python documentation http://docs.python.org/ext/ext.html Unless you know C/C++ well, these are not easy topics. Boost http://www.boost.org/libs/python/doc/tutorial/doc/html/index.html Swig, SIP are other good alternatives. All the above are relatively easy. If your C++ can be simplified to C, Pyrex is remarkably easy to write extensions in. In this case you will import/include a C header containing your function and write a Pyrex wrapper around it rather than directly using Pyrex as a language. If you are on MS Windows, you can always write a COM server in either language (COM in C++ is not easy unless if you are using something like C++ Builder). Or you can simply use popen from Python or use pipes or just read stdout from either side. As you can see, there are a number of options. -- http://mail.python.org/mailman/listinfo/python-list
