Editing Coroutine (section)

===Python===
*[[Python (programming language)|Python]] 2.5 implements better support for coroutine-like functionality, based on extended generators ([https://www.python.org/dev/peps/pep-0342/ PEP 342])
*[[Python (programming language)|Python]] 3.3 improves this ability, by supporting delegating to a subgenerator ([https://www.python.org/dev/peps/pep-0380/ PEP 380])
*[[Python (programming language)|Python]] 3.4 introduces a comprehensive asynchronous I/O framework as standardized in [https://www.python.org/dev/peps/pep-3156/ PEP 3156], which includes coroutines that leverage subgenerator delegation 
*[[Python (programming language)|Python]] 3.5 introduces explicit support for coroutines with async/[[await]] syntax ([https://www.python.org/dev/peps/pep-0492/ PEP 0492]).
*Since [[Python (programming language)|Python]] 3.7, async/await have become reserved keywords.<ref>{{cite web |url = https://docs.python.org/3/whatsnew/3.7.html#summary-release-highlights |title = What's New in Python 3.7 |access-date = 10 September 2021 |archive-date = 28 November 2019 |archive-url = https://web.archive.org/web/20191128153844/https://docs.python.org/3/whatsnew/3.7.html#summary-release-highlights |url-status = live }}</ref>
