Tornado [https://www.tornadoweb.org] is a Python web framework and asynchronous networking library, originally developed at FriendFeed [https://en.wikipedia.org/wiki/FriendFeed]. By using non-blocking with blocking code. asyncio Integration Tornado is integrated with the standard library asyncio [https://docs.python.org/3/library/asyncio.html#module-asyncio] module and shares the same event loop (by since Tornado 5.0). In general, libraries designed for use with asyncio [https://docs.python.org/3/library/asyncio.html#module-asyncio] can be mixed freely with Tornado. Installation pip install tornado
