We're going to talk about CPython and a really cool project that you put on your website and on YouTube called CPPython. We'll be digging into CP python, which is a 10-hour code walk. And we will also talk about this thing called Python Tutor at pythontutor.com that you are working to help people understand the internals of Python better. So that's going to be great stuff. I'm looking forward to it. Yeah.
