Your first Python test. Covers core fundamentals — types, variables, basic operations. A great place to see where you stand.

Deep dive into Python's memory model, object references, and data structures. Essential for understanding performance and debugging memory leaks.

Master Python's Object-Oriented features, including multiple inheritance, the C3 MRO algorithm, and advanced instance creation hooks.

Optimize your Python code with lazy evaluation and functional programming constructs. Covers the iterator protocol, generators, and advanced comprehensions.

Explore Python's concurrency landscape. Understand the limitations of the GIL, when to use threading vs. multiprocessing, and how to write efficient asynchronous code with asyncio.

Deep dive into Python's functional capabilities. Master the LEGB rule, closure mechanics, and the art of writing reusable decorators.

Master the art of writing robust Python applications. Covers advanced exception handling, resource management with context managers, and professional logging strategies.

Focuses on core Python fundamentals, data structures, and common engineering pitfalls. Perfect for junior-level roles.

Second set of junior-level mock interview questions. Tests practical knowledge of strings, mutation, and built-in functions.

Applied reasoning and system design in Python. Tests your understanding of decorators, generators, memory optimization, and asynchronous programming.

Advanced practical scenarios. Focuses on closures, concurrency choices, dictionary internals, and professional dependency management.

Deep system internals and architectural decisions. Covers metaclasses, memory management, profiling, and advanced concurrency patterns.

Advanced engineering challenges. Tests your knowledge of bytecode, security, C extensions, structural typing, and high-performance system design.

The ultimate test for Python experts. Covers CPython internals, complex memory leaks, low-level optimization, and advanced architectural tradeoffs. Not for the faint of heart.
