Knowing some procedural bash and being a certified Associate python programmer at python institute, I still don't recognize OOP patterns unless explicitly stated. I just got hired in a golang centric org. How can I train / learn recognizing and employing OOP patterns or industry standards so I don't have to bother colleagues with my ignorance? (No CS background, education in the humanities.)
