1. Overview
The symmetric_difference_update() method finds the symmetric difference of two sets and updates the set calling it.
The symmetric difference of two sets A and B is the set of elements that are in either A or B, but not in their intersection.
The syntax of symmetric_difference_update() is:
A.symmetric_difference_update(B)
2. Return Value from symmetric_difference_update()
- The
symmetric_difference_update()returnsNone(returns nothing). Rather, it updates the set calling it.
3. Example: Working of symmetric_difference_update()
A = {'a', 'c', 'd'}
B = {'c', 'd', 'e' }
result = A.symmetric_difference_update(B)
print('A =', A)
print('B =', B)
print('result =', result)
Output
A = {'a', 'e'}
B = {'d', 'c', 'e'}
result = None
Here, the set A is updated with the symmetric difference of set A and B. However, the set B is unchanged.
