This course is a deep, rigorous practice-test series built for developers who already know Python syntax but want to master how the language actually works under the hood — and prove it in interviews.

With over 1,400 carefully written multiple-choice questions across six full-length tests, you'll work through every layer of intermediate-to-advanced Python:

Types, Operators & Attribute Mechanics — numeric precision, descriptors, __slots__, attribute lookup order
Control Flow, Generators & Context Managers — yield from, send/throw/close, contextlib, structural pattern matching
Functions, Modules & Decorators — closures, *args/**kwargs, functools, memoization, decorator stacking
Strings, Files, Errors & Inheritance — MRO and the diamond problem, exception chaining, typing.Protocol, encoding
OOP, Stdlib & Metaclasses — __new__ vs __init__, custom metaclasses, dataclasses, dunder methods
Debugging, Patterns, Concurrency & Interview Prep — the GIL, asyncio, threading vs multiprocessing, design patterns, and classic "predict the output" traps

Every question comes with a detailed explanation for every answer choice — not just the correct one — so you understand why wrong answers are wrong, not just what the right answer is. This is the kind of reasoning that separates developers who can write Python from developers who truly understand it.

Whether you're preparing for a technical interview, shoring up gaps before a senior role, or simply want to stop being surprised by Python's quirks, this test series will push your understanding further than tutorials alone can.
