❓ FAQ
QIs copy() a shallow copy?
AYes. However, since set elements must be immutable (hashable) objects, the actual effect of shallow and deep copy is the same.
QDoes the copied set affect the original set?
ANo; modifying the new set does not change the original set.
QWhat type does copy() return?
AA new set object with the same contents as the original, independent and not interfering with it.
