What this snippet does
Forgetting to await a coroutine creates a runtime warning and the task never actually executes.
Expected output
Done RuntimeWarning: coroutine 'sleep' was never awaited
Why practise typing this
Typing concurrency code builds muscle memory for the symbols and indentation Python uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
