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 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 default 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

some core concepts of mypy, including function annotations, the typing [https://docs.python.org/3/library/typing.html#module-typing] module, stub files, and more. If you’re looking for a quick intro, see # Ok! greet_all(ages) # Error due to incompatible types The list [https://docs.python.org/3/library/stdtypes.html#list] type is an example of something called a generic type: it can accept one or more more type parameters. In this case, we parameterized list [https://docs.python.org/3/library/stdtypes.html#list] by writing list[str]. This lets mypy know that greet_all accepts specifically lists containing
