I'm always fascinated how amazing the :python: #Python standard library is.
itertools, collections, dataclasses, subprocess, unittest, logging, argparse, pathlib, json, re, shlex [the list goes on] are all so incredibly useful and you can rely on them as they're always there (paying attention to versioning of course).
And with type hints and #mypy I guess I can stay with just Python for a little longer 😉
