Join Barron Stone for an in-depth discussion in this video Add and remove items from sets, part of Programming Foundations: Real-World Examples.
- Now I think I'm finally done…sorting through my friends.…I finalized my set, and I'm ready to start…inviting people.…(cellphone rings)…Oh!…Excuse me for a sec.…Hey Verne, what's up?…Oh you did?…Um, I'll call you back.…That was my friend Verne,…he heard a rumor that I'm planning a game night,…and wanted to know if he and Jim could join.…I'd love to invite them.…They are really good friends.…Here's the set of friends that I planned to invite.…Let's start by checking to see if Verne is already…in the set of friends to invite.…
And unfortunately no.…I must have taken him out of the set earlier.…Well, since Verne really wants to hang out,…I'll be a good friend and add him back…to the set of friends to invite.…But that raises a problem.…Now I have one to many people in my…set of friends to invite.…So I'm going to need to remove somebody.…- Hey, I was just chatting with Nestor online.…It turns out he's in Romania this week.…- Well I think it's safe to assume that Nestor…won't be making it for game night.…So now there's room for Verne.…
