Abstract Abstract
======== ========
This PEP introduces new syntax for coroutines, asynchronous ``with`` The growth of Internet and general connectivity has triggered the
statements and ``for`` loops. The main motivation behind this proposal proportionate need for responsive and scalable code. This proposal
is to streamline writing and maintaining asynchronous code, as well as aims to answer that need by making writing explicitly asynchronous,
to simplify previously hard to implement code patterns. concurrent Python code easier and more Pythonic.
It is proposed to make *coroutines* a proper standalone concept in
Python, and introduce new supporting syntax. The ultimate goal
is to help establish a common, easily approachable, mental
model of asynchronous programming in Python and make it as close to
synchronous programming as possible.
This PEP improves upon PEP 342, and, in a sense, supercedes it. We
believe that the changes proposed here will help keep Python
relevant and competitive in a quickly growing area of asynchronous
programming, as many other languages have adopted, or are planning to
adopt, similar features: [2]_, [5]_, [6]_, [7]_, [8]_, [10]_.
