A few years ago, I wrote a long series of tutorials showing how to embed Python into a C/C++ program, and periodically threatened to write another series showing how to go the other way i.e. extend Python by calling your own C/C++ codeTypically because you want better performance, or because you want to run it multi-threaded, which Python is known to not handle very well..
Well, I've finally made good on that promise and written some tutorials on how to write a Python extension module:
|A minimal setup||How to create a minimal Python extension module.|
|Calling functions||How to define a C/C++ function and call it from Python.|
|Handling errors||How to pass errors back to the calling Python code.|
|Callbacks||How to call back into Python from the C/C++ code.|
|Managing the GIL||How to manage the GIL, for better multi-threaded performance.|
Never let it be said that I don't keep my promises!
