improvement and adaptiveness. What is decisive is not the form of the organization, but how people act and react. The roots of Toyota’s success lie not in its organization structures, but in developing capability

http_client.fetch(url) return response.body And here is the same function rewritten asynchronously as a native coroutine: from tornado.httpclient import AsyncHTTPClient async def asynchronous_fetch(url): http_client 15Tornado Documentation, Release 6.5.1 Native vs decorated coroutines Python 3.5 introduced the async and await keywords (functions using these keywords are also called “native corou- tines”). For compatibility you can use “decorated” or “yield-based” coroutines using the tornado.gen.coroutine decorator. Native coroutines are the recommended form whenever possible. Only use decorated coroutines when compatibility
