Asynchronous context manager

Question

I have an asynchronous API which I\'m using to connect and send mail to an SMTP server which has some setup and tear down to it. So it fits nicely into using a context

Answer 1

The asyncio_extras package has a nice solution for this:

import asyncio_extras

@asyncio_extras.async_contextmanager
async def smtp_connection():
    client = SMTPAsync()
    ...

For Python < 3.6, you'd also need the async_generator package and replace yield client with await yield_(client).
