Hello @Ashey Editz
I suggest you to use App Service Linux Docker and create your custom docker image based on nodejs and install python as there is no official docker image that has both nodejs and python in it.
I would not recommend to use 3rd party unofficial docker images as they may have security vulnerabilities.
Dockerfile example:
FROM node:16
RUN apt-get update -yq \
&& apt-get install python -yq
