There are many languages that can be used to create a web page: HTML, HTML5, JavaScript, PHP, etc… But Python? Apparently yes, as MicroWebSrv lightweight web server – mostly designed for ESP32 platforms running MicroPython such as Pycom boards – supports inserting Python code inside “HTML” files with the extension .pyhtml. The code can be found in Github, and is only comprised of three files. microWebSrv.py – The Web server microWebSocket.py – The optional support of WebSockets microWebTemplate.py – The optional templating language for .pyhtml rendered pages Beside HTML/Python files, the web server can handle GET, POST, … requests, an embedded full REST API, routing handlers, WebSockets, etc… That’s what a mixed HTML + Python .pyhtml file may look like:

You can use double curly braces {{ and }} to insert MicroPython code, if statements, for loops, or includes. I’m not sure if this makes really sense for all […]
