Senior Deep-Dives L5 PRO · 101 lessons asyncio internals, GIL, typing tricks, Rust extensions
100 lessons across 6 modules: concurrency & async internals, CPython internals & performance, metaclasses + descriptors + dunder magic, memory + profiling + optimization (memray/tracemalloc), and architecture + code review + senior judgment.
ℹ️ Heads-up on the format: Senior Deep-Dives are mostly concept lessons + code reviews + predict-the-output exercises. Some samples touch CPython internals or C-extension boundaries that Skulpt/Pyodide can't execute — those run as walkthroughs, not live-runnable code.
