Under the Hood of CPython

Source Code (.py) ──► Lexer & Parser (AST) ──► Compiler ──► Bytecode (.pyc) ──► PVM Loop
                                                                                  │
                                                                   [Garbage Collector & Ref Count]

By understanding that Python executes optimized bytecode within the PVM rather than pure line-by-line interpretation, developers can optimize memory allocations, minimize dictionary lookups, and build high-throughput AI backends.
