Quick Answer
Custom context managers: class-based: implement __enter__ and __exit__. __exit__ receives exception info (exc_type, exc_val, exc_tb) and can suppress exceptions by returning True. Function-based (simpler): use @contextlib.contextmanager decorator, yield once (code before yield = __enter__, after yield = __exit__). contextlib.ExitStack manages multiple context managers dynamically.
