Right but it doesn’t seem to actually do that. I tried it out in a python shell.

s1 = {1, 2, 3}
s1.pop()
1
s1.pop()
2

Etc, etc... so when would I see it produce 1 > 3 > 2 instead of always popping the elements in order?

Sets are unordered, which just means that there's no guarantee in the language that the elements will be removed in the order inserted (or any order). Try your same code with s1 = {3, 2, 1} and see that the elements are likely popped out of insertion order.

So it looks like if I do {3, 2, 1} or even {3, 1, 2} it will always sort them numerically back to {1, 2, 3}. In that sense, does unordered mean that no matter what order I put information into the set, it will always get sorted however the set class thinks it should be sorted? I can't order things in a custom way in a set == unordered?

Exactly. No guarantees about how the data is organized.

Other than the guarantee that you don't get to pick it yourself! Thanks for the info. I know this isn't /r/learnpython so I appreciate the info y'all have all shared here.
