bookRemove() and Discard() Methods

In sets, you can remove elements using the remove() method. 


              
123456

            
set_1 = {10, 20, 30, 40, 50, 60, 70}
print(set_1)

set_1.remove(50)
set_1.remove(60)
print(set_1)
copy

Note

If the element you're trying to remove isn't in the set, you'll get a KeyError.

set_1 = {10, 20, 30, 40, 50, 60, 70}
set_1.remove(999)
copy

There's another way to get rid of items from a set: the discard() method. Unlike remove(), discard() won't throw a KeyError if the item you want to remove isn't there — it just leaves the set as is.

set_1 = {10, 20, 30, 40, 50, 60, 70}
print(set_1)

# Remove() method
set_1.remove(50)
set_1.remove(60)
print(set_1)
 
# Discard() method
set_1.discard(10)
set_1.discard(20)
set_1.discard(999)
