" summary

Live demos on Python 3.6 implement concrete behaviors: add a class with __init__, __repr__, __add__, __len__ and it prints and adds as expected; disassemble and monkeypatch __build_class__ to intercept class creation; enforce subclass contracts with a metaclass and with __init_subclass__; write and apply a timer decorator and an n-times decorator; convert long computations to generators and use contextlib.contextmanager to wrap a generator as a context manager (SQLite temp table example) — everything runs in the demo.
