Python

Dynamic typing, built-in types, type hints.

if / for / while / match — the Python way.

def, *args / **kwargs, defaults, lambdas.

list, dict, set, tuple — and the syntax that makes them sing.

Objects, dunders, dataclasses, properties.

import, packages, virtualenvs, the standard library.

try / except / else / finally + EAFP.

Lazy sequences, yield, and the itertools toolbox.

@decorators, async / await, and the event loop.
