🐍 Python

Master Python's object model — mutability, is vs ==, dicts, sets, comprehensions, and truthiness — to write idiomatic code that dodges silent data bugs.

Command *args/**kwargs, closures, decorators, and LEGB scope — and sidestep the late-binding and mutable-default-argument traps that bite every Python engineer.

Hook into Python's data model with dunder methods, tame multiple inheritance via C3 MRO, slim instances with __slots__, and ship clean value types using dataclasses.

Build lazy pipelines with the iterator protocol and yield, then read the GIL to choose threads, asyncio, or multiprocessing for I/O- versus CPU-bound work.
