CPython
CPython is the reference implementation of the Python programming language, written primarily in C and providing its interpreter and runtime.
Fast Python: High performance techniques for large datasets
- How it is used
- Uses CPython as the default implementation for examining Python data-processing performance, memory use, and threading limits.
- How deep it goes
- Explains the GIL’s threading constraint and probes memory estimates, but does not provide a complete analysis of CPython’s performance.
- Examples
- Uses timed matrix multiplication across implementations and `sys.getsizeof` measurements of data containers.
- What you can do after
- Diagnose/debug with it by checking whether interpreter execution, the GIL, or misleading memory estimates affect a performance decision.

Python Concurrency with asyncio
The standard reference implementation of the Python programming language, written primarily in C.
- How it is used
- Frames CPython as the runtime constraint for understanding Python threading performance and shared-state safety.
- How deep it goes
- Explains reference counting, the GIL, race conditions, and timing evidence, but stops short of implementation-level internals.
- Examples
- Uses recursive Fibonacci timing and a reference-count race condition to demonstrate concurrency limits.
- What you can do after
- Evaluate/understand: Compare sequential and threaded CPU-bound work and recognize when multiprocessing is relevant.
