Python Basic to Advance

This isn't a syntax tour. It's a 30-module Python curriculum built around how Python is actually used in production — language fundamentals plus the depth most prep platforms never reach: the GIL and what it actually limits, the iterator protocol and generator pipelines, the descriptor protocol and metaclasses, the import system, the Python memory model, bytecode and the interpreter loop.

You'll work through the fundamentals (variables, control flow, strings, lists, tuples, sets, dictionaries), the full object-oriented model (classes, inheritance, polymorphism, encapsulation, advanced OOP including descriptors and metaclasses), and the depth that separates mid from senior offers: functional patterns, type hints with mypy, concurrency across threads/processes/asyncio, testing with pytest, databases with SQLAlchemy, web frameworks (Flask, FastAPI), the numerical stack (NumPy, pandas, Matplotlib), Python internals, engineering best practices — closing with a dedicated interview-synthesis module.

Every module and every topic in this course is free. Three high-stakes topics feature first-person guest bylines from AlgoInsight founders working in those specialisms day-to-day.
