Python set symmetric_difference_update()
The symmetric difference of two sets is the set of elements which are in either of the sets but not in both of them.
Symmetric Difference is marked in Green
symmetric_difference() method returns a new set which contains symmetric difference of two sets. The symmetric_difference_update() method updates the set calling symmetric_difference_update() with the symmetric difference of sets.
Syntax:
A.symmetric_difference_update(B)
Parameters:
The symmetric_difference takes a single “set” as a argument.
Returns:
This method returns None (which indicates absence of a return value). It only updates the set calling symmetric_difference_update() with the symmetric difference of sets.
CODE 1
# Python code to demonstrate working of # symmetric_difference_update() A = {'p', 'a', 'w', 'a', 'n'} B = {'r', 'a', 'o', 'n', 'e'} # result is always none. result = A.symmetric_difference_update(B) print('A = ', A) print('B = ', B) print('result = ', result) |

filter_none
Output:
('A = ', set(['e', 'o', 'p', 'r', 'w']))
('B = ', set(['a', 'r', 'e', 'o', 'n']))
('result = ', None)
CODE 2
# Python code to demonstrate working of # symmetric_difference_update() A = {'s', 'u', 'n', 'n', 'y'} B = {'b', 'u', 'n', 'n', 'y'} # result is always none. result = A.symmetric_difference_update(B) print('A = ', A) print('B = ', B) print('result = ', result) |

filter_none
Output:
('A = ', set(['s', 'b']))
('B = ', set(['y', 'b', 'u', 'n']))
('result = ', None)
