Remove Item
To remove an item in a set, use the remove(), or the discard() method.
Example
thisset = {"apple", "banana", "cherry"}
thisset.remove("banana")
print(thisset)
Note: If the item to remove does not exist,
remove()will raise an error.
Example
thisset = {"apple", "banana", "cherry"}
thisset.discard("banana")
print(thisset)
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.
Example
thisset = {"apple", "banana", "cherry"}
x =
thisset.pop()
print(x)
print(thisset)
Note: Sets are unordered, so when using the
pop()method, you do not know which item that gets removed.
Example
thisset = {"apple", "banana", "cherry"}
thisset.clear()
print(thisset)
Example
thisset = {"apple", "banana", "cherry"}
del
thisset
print(thisset)
