27. Evaluation Loop
The main evaluation loop in Python/ceval.c, opcode dispatch via computed gotos, and the eval breaker mechanism.
39. Closures and Cells
MAKE_CELL, LOAD_DEREF, STORE_DEREF opcodes and the PyCellObject that captures variables in enclosing scopes.
38. Comprehensions
How list/dict/set comprehensions and generator expressions compile to nested code objects with implicit iteration.
37. Pattern Matching
match/case compilation to MATCH_* opcodes, pattern semantics, and guard evaluation in the interpreter.
36. Coroutines and Async
async def, await, SEND opcode, coroutine wakeup, and how asyncio integrates with CPython's coroutine machinery.
35. Generators
Generator object internals, YIELD_VALUE and RESUME opcodes, and frame suspension and resumption mechanics.
34. Exception Handling
Exception tables, the try/except/finally bytecode pattern, exception chaining, and the unwinding protocol.
33. Attribute Lookup
LOAD_ATTR bytecode, __getattribute__ dispatch, the descriptor protocol, and type version tag caching.
31. Function Calls
CALL opcode mechanics, positional and keyword argument handling, *args/**kwargs unpacking, and call overhead.
30. Bytecode Instructions
Catalogue of CPython opcodes: LOAD/STORE variants, binary ops, comparison, jumps, and call instructions.
29. Stack-Based Execution
The value stack, operand push/pop discipline, and how the interpreter maintains stack depth invariants.
28. Frames
PyFrameObject and _PyInterpreterFrame layout, frame creation, the frame stack, and frame introspection.
