Thank you. My knowlage is too slim, it sounds lake Greek Ancient to me.
I badly need examples I could follow the mechanics to be able to learn, I believe.
Edit:
I searched openrepos to find apps with source code, to copy/understand mechanisms. The difficulty is that they are generally too complex and I am lost in the code and multiple files.
E.g. a small ap which at most would ask a word to the user and write it with python into a file.
Any simple app idea?
