Python .symmetric_difference_update()

In Python, the .symmetric_difference_update() method updates the original set by removing the items present in both sets and adding items unique to each set.

Syntax

The syntax for using this method is:

set1.symmetric_difference_update(set2)

Or in a more compact form :

set1 ^= set2

• set1: Refers to the original set.
• set2: This is the set to be compared with the original set.

Example

The following example removes items present in both store1 and store2 and adds unique items from store2 to store1 set:

store1 = {'apple', 'mango', 'lichi', 'orange', 'banana'}
store2 = {'strawberry', 'banana', 'pear', 'raspberry'}

store1.symmetric_difference_update(store2)

print(store1)
