Understand Python's hybrid execution model - source code, bytecode, the Python Virtual Machine, CPython internals, JIT compilation, and why this architecture matters for performance and system design.
How Python actually executes code - the complete 5-stage pipeline from source text through tokenization, AST, bytecode compilation, and the Python Virtual Machine. Covers stack frames, heap memory, .pyc files, import caching, LEGB scope, and the CPython GIL at engineering depth.
Solve 12 Python compilation vs interpretation problems. Covers compilation practice, bytecode exercises, dis module. Hints and solutions.
Master the Python REPL at the engineering level - how Read-Eval-Print-Loop works internally, bytecode compilation in interactive mode, state persistence, the underscore variable, multi-line input, IPython, and professional use cases far beyond beginner experimentation.
