Welcome Saud,
Nope. JS for the frontend and for the backend you have nodejs, php and asp.
That being said, if you want to reuse something in PY there is no reason why you can not write your own PY code, run it on a server and communicate with Wappler backend/frontend via API.
I hope you get it repaired or a new one soon so you can join us 
I am guessing you are a backend guy then.
My design skills have impressed a lot of people here so don't hesitate to ask for help. Specially if it's related to photoshop.
