How Can I edit and update my .config (for my python application) file using WebSockets exactly like how we edit and update router .config file?

[T Obulesu]

I have my python application running on Raspberry Pi and it needs to be 
configured every time. Hence I want to access this .config file over online and 
configure it exactly like how we can configure our router, but I want to use 
only web sockets.
