Complete masterclass from core memory models and data structures to OOP, FastAPI, Asyncio, Profiling, Metaprogramming, and production deployment.
Complete all 22 milestones to unlock and download your verified certificate (22 remaining).
Mutability, memory allocations, reference counts, data structures, and idiomatic Pythonic patterns.
CPython compact dict internals, deque ring buffers, heapq priority queues, bisect, and Trie implementations.
First-class functions, args/kwargs unpacking, lexical scoping, closures, and lambda expressions.
Class lifecycle (__new__ vs __init__), 4 pillars, MRO C3 linearization, dunder methods, __slots__, descriptors, and Protocols.
functools.wraps, timing/logging wrappers, parameterized decorators, and class-based decorators.
The iterator protocol (__iter__, __next__), memory-efficient yield generators, and the itertools toolkit.
EAFP vs LBYL internals, try/except/else/finally mechanics, custom hierarchies, ExceptionGroup, and ExitStack.
Reading/writing files safely with context managers, modern pathlib operations, and JSON/CSV structured parsing.
Structuring modules and packages, __init__.py, relative imports, virtual environments, and pyproject.toml.
Python 3.10+ typing (Union/Optional | syntax), TypedDict, Generic TypeVars, Protocols, and mypy static analysis.
NFA engine internals, ReDoS prevention, compile flags, zero-width lookarounds, conditional groups, and log parsing.
Writing test suites with pytest, assertions, reusable fixtures with teardown, parametrized tests, and mocking.
CPython GIL constraints, ThreadPoolExecutor vs ProcessPoolExecutor, and synchronization locks.
Coroutines, event loop lifecycle, asyncio.gather, TaskGroup, timeouts, semaphores, and async context managers.
HTTP/1.1 vs HTTP/2 multiplexing, requests.Session pooling, httpx async client architectures, and rate limiting.
POSIX standards and exit codes, argparse subparsers, type-driven Typer applications, and Rich terminal formatting.
BaseModel, Field constraints, nested models, field/model validators, computed fields, and pydantic-settings.
Path/query params, Pydantic request models, Depends dependency injection, and X-API-Key security.
Raw DB-API SQL, SQLAlchemy ORM modeling, relationships, querying, and async database drivers.
CPython PyMalloc arena architecture, cyclic GC generational tuning, tracemalloc snapshots, and zero-copy memoryview.
