Python Developer

Installing Python (3.12+), configuring VS Code with extensions (Pylance, Black, Ruff), isolated virtual environments (venv), and pip package management.

Dynamic typing, immutable vs mutable types (int, float, str, bool, bytes), type annotations (typing module), and type checking with MyPy.

Boolean logic, if/elif/else statements, for-loops with range/enumerate/zip, while-loops, break/continue/else loop clauses, and modern match/case pattern matching.

List amortized array mechanics, tuple immutability and packing/unpacking, dictionary hash maps and collision resolution, and set hashing.

collections module (deque, defaultdict, Counter, OrderedDict, namedtuple) and itertools (chain, cycle, groupby, combinations, permutations).

Classes, instances, self, __init__, __repr__, __str__, operator overloading (__eq__, __lt__, __add__), and object lifecycle protocols.

First-class functions, closures, LEGB scope resolution, function decorators, class decorators, functools.wraps, and functools.lru_cache.

Modern declarative data containers with @dataclass, frozen immutability, field factories, and Pydantic v2 validation models.

Everything in Python is an object. Examining PyObject, ob_refcnt, ob_type, variable name pointers, and the id() memory address.

Generational garbage collection (Gen 0, 1, 2), detecting circular reference cycles, gc module inspection, and weak references (weakref).

The Global Interpreter Lock (GIL), I/O-bound vs CPU-bound tasks, concurrent.futures, asyncio coroutines, event loops, and free-threaded Python (PEP 703).

Contiguous memory buffers, striding, memory views, broadcasting internals, and interfacing Python with BLAS/LAPACK libraries.

Asynchronous endpoints with FastAPI, Uvicorn worker clustering, streaming responses (Server-Sent Events), and integrating model backends.
