    ...performance advantage of low-level code, you can write extension modules in C or C++, or wrap existing code with SWIG or Boost.Python. Wrapped modules appear to your program exactly like native Python code. That's language integration made easy. You can also go the opposite route and embed Python in your own application, providing your users with a language they'll enjoy using. Python runs everywhere Python is available for all major operating systems: Windows, Linux/Unix, OS/2, Mac, Amiga, am...
