This session will provide an overview of integrating external executable tools and high-performance in-process C/C++ native code from Python using the Python standard library and the Python APIs.

This presentation will cover using Python's built-in libraries to integrate code, both as command-line utilities written in any language as well as high performance, in-process native code written in C or C++.

• Starting point with Script Tools
• Wrapping a command line utility as a script tool
  • Using subprocess
  • Using the script to do setup/teardown for the external tool
• Writing C++ ArcObjects code
  • Introduction to CTypes
  • Putting what we learned from wrapping into practice on in-process code

The recorded video demos and the compiled DLL (along with all the code as it was presented) is available as a binary release on this project.
