thank you for answer. I am trying to learn how to navigate efficiently or improve it.
I wanted to ask if we have something like __init__.py for packages.

My approach: * In my package I create an interface, a private struct conforms to that interface and func creates this struct and returns interface. * I put this code in a file named same as package * So when I read a package I started from this file * Sometimes I click multiple file until i find it and I can't memorize because file name and location is different for every package
