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)
The above code will produce a modified store1
set as follows:
{'apple', 'mango', 'lichi', 'orange', 'strawberry', 'pear', 'raspberry'}
Note: A set in Python is unordered. This means that the order of items can change in the above output.
