How To Remove An Element From A Set In Python

Chapter: Python Last Updated: 19-05-2023 03:18:06 UTC

Program:

            /* ............... START ............... */
                
my_set = {1, 2, 3, 4, 5}
my_set.remove(3)  # Remove the element 3 from the set

print(my_set)  # Output: {1, 2, 4, 5}




my_set = {1, 2, 3, 4, 5}
my_set.discard(3)  # Remove the element 3 from the set if present

print(my_set)  # Output: {1, 2, 4, 5}

my_set.discard(6)  # No exception raised since 6 is not present in the set

print(my_set)  # Output: {1, 2, 4, 5}

                /* ............... END ............... */
        

Notes:

  • In Python, you can remove an element from a set using the remove() or discard() methods. Both methods allow you to remove an element from a set, but they differ in their behavior when the element is not found in the set.
  • If the element you're trying to remove is not present in the set, the remove() method will raise a KeyError. To avoid this exception and handle the case when the element may or may not be present in the set, you can use the discard() method:
  • Note that the discard() method silently does nothing if the element is not found in the set, while remove() raises an exception. Choose the appropriate method based on whether you want to handle the absence of the element explicitly or not.
