Python Set symmetric difference Method | Example code

  • by

Use symmetric_difference() method to get the symmetric difference set in Python. This method returns a new set that contains all items from both sets, but not the items that are present in both sets


Python Example get the Set symmetric difference

Simple example code gets the elements that are not common in both sets.

set1 = {1, 2, 3, 4, 5}

set2 = {1, 2, 3, 6, 0}

new_set = set1.symmetric_difference(set2)



Python Set symmetric difference Method

Another example

Find the symmetric difference using the ^ operator.

set1 = {'A', 'B'}

set2 = {'A','C'}

new_set = set1 ^ set2


Output: {‘C’, ‘B’}

The symmetric_difference() method vs symmetric difference operator (^)

The symmetric_difference() method accepts one or more iterables that can be strings, lists, or dictionaries. And the symmetric difference operator (^) only applies to sets. If you use it with the iterables which aren’t sets, you’ll get an error.

set1 = {'A', 'B'}

set2 = ['A','C']

new_set = set1 ^ set2


Output: TypeError: unsupported operand type(s) for ^: ‘set’ and ‘list’
