Taking Asynchronous Python to the Next Level Using Trio
summary
Practical tour of Trio that focuses on concrete APIs and behaviors: structured concurrency with nurseries and start_soon that guarantee children finish before parent, cooperative multitasking via checkpoints, cancellation and timeouts with move_on_after and CancelScope, aggregated errors handled as Python 3.11 exception groups, channels and semaphores for synchronization, SSL stream and Trio Path (pathlib) for nonblocking IO, trio-asyncio adapters, run_sync_in_thread with thread naming, and new testing helpers race_group and matchers.
