Ok, I checked the answers you all gave me, and the suggestions seem to be 2:
a. Compute the list of members on the fly, with a list comprehension that looks up stuff on self.__dict___; b. Stay with my solution, but substituting the unnecessary "if-else" by a simple "if". In sum, maintain a list of members that is updated whenever a member is added or removed. Which one is better? I am new to all this, so please correct me if I am wrong. It seems that (a) is better if you do a lot of adding/removing members operations compared to the number of lookups to the "members" list. Otherwise, (b) is better. Right? In my application, I will do many more lookups on the members list than adding/removing members (this sounds weird, feels like I'm Dr. Frankenstein), so I will go with (b).
