Understanding and expanding Python: hand-on experience with the Python internals
On this tutorial you will learn to:
- Explore the core of the standard Python implementation
- Modify the interpreter by adding new functions
- Extend Python with C, Rust, and Zig.
The session will be a combination of a theoretical introduction of the topics, followed by a hand-on experience on each step.
Here is an outline of what will be done:
- Navigating CPython (short presentation)
- Setting up a development environment
- Compiling CPython from source
- Adding a free function to the interpreter
- Adding a new method to a Python container (list or set)
- Extending CPython (short presentation)
- Minimal C-extension for "Hello World"
- Minimal Rust, and Zig extensions for "Hello World",
- Create a new extension replacing Python functionality with C, Rust and Zig.
