Python Set Methods


Python has a set of built-in methods that you can use on sets.

Method Shortcut Description
add()   Adds an element to the set
clear()   Removes all the elements from the set
copy()   Returns a copy of the set
difference() - Returns a set containing the difference between two or more sets
difference_update() -= Removes the items in this set that are also included in another, specified set
discard()   Remove the specified item
intersection() & Returns a set, that is the intersection of two other sets
intersection_update() &= Removes the items in this set that are not present in other, specified set(s)
isdisjoint()   Returns whether two sets have a intersection or not
issubset() <= Returns whether another set contains this set or not
  < Returns whether all items in this set is present in other, specified set(s)
issuperset() >= Returns whether this set contains another set or not
  > Returns whether all items in other, specified set(s) is present in this set
pop()   Removes an element from the set
remove()   Removes the specified element
symmetric_difference() ^ Returns a set with the symmetric differences of two sets
symmetric_difference_update() ^= Inserts the symmetric differences from this set and another
union() | Return a set containing the union of sets
update() |= Update the set with the union of this set and others
