Make it easier to extend Python with C++

PyCXX is a set of C++ facilities to make it easier to write Python extensions. The chief way in which PyCXX makes it easier to write Python extensions is that it greatly increases the probability that your program will not make a reference-counting error and will not have to continually check error returns from the Python C API.

PyCXX integrates Python with C++ in these ways

  • C++ exception handling is relied on to detect errors and clean up. In a complicated function this is often a tremendous problem when writing in C. With PyCXX, we let the compiler keep track of what objects need to be dereferenced when an error occurs.
  • The Standard Template Library STL and its many algorithms plug and play with Python containers such as lists and tuples.
  • The optional CXX_Extensions facility allows you to replace the clumsy C tables with objects and method calls that define your modules and extension objects.
