Sets in Python are mutable, so elements can be removed after creation.

remove( ) method :
                remove( ) deletes the given element. 
                If the item does not exist, it will throw error
Python 
fruits = {"apple", "banana", "mango"} fruits.remove("banana") print(fruits) #output {'apple', 'mango'}

discard( ) method :
               Removes the item only if it exists. 
               If the item does not exist, no error is occured. 

Python 
numbers = {1, 2, 3} numbers.discard(2) print(numbers) #output {1, 3}
pop( ) method :
              Since sets are unordered , pop( ) removes any arbitary element. 
              
Python 
colors = {"red", "blue", "green"} item = colors.pop() print(colors) print("Removed:", item) #output Removed: green #Output may vary
clear( ) method :
              Deletes all the elements , but keeps the set object. 
Python 
data = {10, 20, 30} data.clear() print(data) #output set()

del :
            Deletes the entire set object. 
Python 
numbers = {1, 2, 3} del numbers print(numbers) #output Name Error
