Async Generators: `yield` in an `async` World

Source: peps.python.orgadvanced

Async generators let you write I/O-bound data streams with the elegance of `yield`. An `async def` function with `yield` produces values one at a time, pausing for I/O without blocking. This is ideal for streaming data from a database.

Async generators are the asynchronous version of regular generators, letting you write data producers that can pause for I/O. An `async def` function with `yield` creates a stream of values that can be consumed with `async for`. This avoids writing a verbose iterator class with `__aiter__` and `__anext__` methods. It's perfect for streaming database results or network data where each chunk requires an `await`.
