Python class variables are where most beginners and even working developers silently break their OOP code — and in this Part 2 of Python OOP for Agentic AI engineers, we fix that for good. You’ll see a real team-collaboration bug that no error message catches, lock your class down with __slots__, and then unpack class variables vs instance variables with a hands-on Employee example: shared raise percentages, employee counters, and the exact rules Python uses to look up an attribute. By the end you’ll know when to use self, when to use the class name, and why this matters the moment you start building Agentic AI systems where every wrong attribute becomes a production incident.
