Run Python scripts and modules, create a virtual environment, install dependencies, format code with Ruff, and understand the entry-point pattern.

Use lists, tuples, dictionaries, sets, slicing, comprehensions, functions, and argument unpacking while avoiding mutable-default traps.

Structure imports, work with pathlib, read and write files through context managers, and handle exceptions without swallowing failures.

Build a command-line task manager with argparse, JSON persistence, filtering, validation, tests, and a layout that can grow.
