Async checklist

Use create an async function.
Await inside async functions.
Combine with loops carefully.

Async function definitions

Declare async functions using a readable sentence that maps to Python async def.

async.pln

create an async function named fetch_data that takes url and returns await requests.get(url)

Awaiting in blocks

Inside async functions, you can await inside loops or conditions.

awaits.pln

create an async function named process_items that takes items and does
    for each item in items do
        result = await process_item(item)
        print result

Async guidance

Only use await inside async functions.
Wrap network calls to keep flows readable.
Use async endpoints for high concurrency APIs.
