Remove Item

To remove an item in a set, use the remove(), or the discard() method.

python

thisset = {"apple", "banana", "cherry"}
  thisset.remove("banana")
  print(thisset)

Note: Note: If the item to remove does not exist, remove() will raise an error.

python

thisset = {"apple", "banana", "cherry"}
  thisset.discard("banana")
  print(thisset)

Note: Note: If the item to remove does not exist, discard() will NOT raise an error.

You can also use the pop() method to remove an item, but this method will remove a random item, so you cannot be sure what item that gets removed.

The return value of the pop() method is the removed item.

python

thisset = {"apple", "banana", "cherry"}
  val_1 =
  thisset.pop()print(val_1)
  print(thisset)

Note: Note: Sets are unordered, so when using the pop() method, you do not know which item that gets removed.

python

thisset = {"apple", "banana", "cherry"}
  thisset.clear()
  print(thisset)

python

thisset = {"apple", "banana", "cherry"}
  del
  thisset
  print(thisset)
