Definition 
Return the symmetric difference of two sets as a new set.

Syntax
set(x).symmetric_difference(y)

Parameters
x,y=set items

Examples
The return is:
set1={3,1,44,66}set2={2,3,33,44}
set3=set1.symmetric_difference(set2)
print(set3)

>>> 
{33, 2, 1, 66}
>>> 

set.symmetric_difference()
The result is:
 >>> from decimal import Decimal
>>> a=set()
>>> a.add(Decimal(1).adjusted())
>>> a.add(Decimal(.55).canonical())
>>> a.add(Decimal(-1).compare_signal(1))
>>> a
{0, Decimal('0.5500000000000000444089209850062616169452667236328125'), Decimal('-1')}
>>> b=set()
>>> b.add(Decimal(1).compare_total(2))
>>> b.add(Decimal(0.1).copy_abs())
>>> b
{Decimal('0.1000000000000000055511151231257827021181583404541015625'), Decimal('-1')}
>>> a.symmetric_difference(b)
{Decimal('0.1000000000000000055511151231257827021181583404541015625'), Decimal('-1')}
