# Python Set symmetric_difference()

• Difficulty Level : Easy
• Last Updated : 06 Feb, 2018

The symmetric difference of two sets set1 and set2 is the set of elements which are in either of the sets set1 or set2 but not in both. Syntax :

`set1_name.symmetric_difference(set2_name) `

Parameters :
It only takes a single set as the parameter. If a list, tuple or dictionary is passed it converts it a set and performs the task.

Return value :

`Returns a set which is the symmetric difference between the two sets. `

Working Code for symmetric_difference() :

 `# Python program to demonstrate the use of ``# of symmetric_difference() method `` ` ` ` `list1 ``=` `[``1``, ``2``, ``3``] ``list2 ``=` `[``2``, ``3``, ``4``] ``list3 ``=` `[``3``, ``4``, ``5``] `` ` `# Convert list to sets``set1 ``=` `set``(list1) ``set2 ``=` `set``(list2) `` ` `# Prints the symmetric difference when  ``# set is passed as a parameter ``print``(set1.symmetric_difference(set2)) `` ` `# Prints the symmetric difference when list is ``# passed as a parameter by converting it to a set``print``(set2.symmetric_difference(list3))`

Output :

```{1, 4}
{2, 5}
```
