Title: PEP 492 – Coroutines with async and await syntax | peps.python.org

Open Graph Title: PEP 492 – Coroutines with async and await syntax | peps.python.org

Description: The growth of Internet and general connectivity has triggered the proportionate need for responsive and scalable code. This proposal aims to answer that need by making writing explicitly asynchronous, concurrent Python code easier and more Pythonic.
