initial value is an integer. If the initial value doesn’t provide enough information (or if there isn’t an initial value), specify the type by writing it after the variable, separated by a colon. 1 let are actual values, not just another way of writing their raw values. In fact, in cases where there isn’t a meaningful raw value, you don’t have to provide one. PDF conversion courtesy of www.appsdissected handle the absence of a value. Optionals say either “there is a value, and it equals x” or “there isn’t a value at all”. Using optionals is similar to using nil with pointers in Objective-C, but they work

async def handler(websocket, path): await asyncio.sleep(1) This is part of learning asyncio. It isn’t specific to websockets. See also Python’s documentation about running blocking code. How can I connection when the handler exits. How do I run a HTTP server and WebSocket server on the same port? This isn’t supported. Providing a HTTP server is out of scope for websockets. It only aims at providing a WebSocket websockets takes care of responding to pings with pongs. Is there a Python 2 version? No, there isn’t. websockets builds upon asyncio which requires Python 3. 1.2. FAQ 17 websockets Documentation

of this document is to give you enough technical specifics to understand how Django works, but this isn’t intended to be a tutorial or reference – but we’ve got both! When you’re ready to start a project -m django --version If Django is installed, you should see the version of your installation. If it isn’t, you’ll get an error telling “No module named django”. This tutorial is written for Django 2.2, used in a couple of introspective parts of Django, and it doubles as documentation. If this field isn’t provided, Django will use the machine- readable name. In this example, we’ve only defined a human-readable
