Python Programming

Python syntax, memory model, data structures, list comprehensions, object-oriented concepts, and standard library tools.

1Python Syntax & Memory Model Basics

Variables, primitive types, dynamic typing, mutability vs immutability, and reference counting.

2Control Flow, Functions, Closures & LEGB Scope Resolution

Bytecode execution loop (CEval), frame objects, LEGB scope resolution, first-class functions, lexical closures, and metadata-preserving decorators.

Control Flow, Functions & Scope Resolution

Lexical closures, frame evaluation, nonlocal scope bindings, and high-order decorator composition.

Control Flow, Functions & Scope Resolution

Master CPython's execution frame stack, bytecode disassembly, LEGB lexical scope resolution, closure cell bindings (`__closure__`), and high-performance decorator patterns.

3Built-in Data Structures: Hash Table Internals, Dynamic Arrays & Comprehensions

CPython PyDictObject compact hash tables, perturbation probing, PyListObject geometric memory reallocation, and list/dict comprehension bytecode optimizations.

Built-in Data Structures & Comprehensions

Hash table layout, collision resolution, array over-allocation growth factors, and comprehension bytecode efficiency.

Built-in Data Structures & Comprehensions

Analyze CPython's compact dictionary architecture (`PyDictObject`), open addressing with perturbation probing, dynamic array over-allocation formulas (`PyListObject`), and comprehension performance.

4Modules, Import Mechanics, Packaging & Exception Topologies

The Python import system, sys.modules cache, importlib loaders, circular import mitigation, exception topologies, and transactional context managers.

Modules, Packages & Exception Handling

Module loader protocols, sys.meta_path finders, circular import debugging, custom exception hierarchies, and RAII context management.

Modules, Packages & Exception Handling

Master the CPython import protocol (`sys.modules`, `sys.meta_path`), resolve circular dependency cycles, design domain exception hierarchies, and implement transactional rollback context managers.
