Python collection symmetric_difference() usage and example

Méthodes de collection en Python

The Python symmetric_difference() method returns the symmetric difference sets of two groups.

The symmetric difference of two sets A and B is the set of elements that are in A or B, but not at their intersection.

The syntax of symmetric_difference() is:

A.symmetric_difference(B)

Example1The work of :symmetric_difference()

A = {'a', 'b', 'c', 'd'}
B = {'c', 'd', 'e'}
C = {}
print(A.symmetric_difference(B))
print(B.symmetric_difference(A))
print(A.symmetric_difference(C))
print(B.symmetric_difference(C))

Output result

{'b', 'a', 'e'}
{'b', 'e', 'a'}
{'b', 'd', 'c', 'a'}
{'d', 'e', 'c'}

Symmetric difference set using ^ operator

In Python, we can also use the ^ operator to find the symmetric difference set.

A = {'a', 'b', 'c', 'd'}
B = {'c', 'd', 'e'}
print(A ^ B)
print(B ^ A)
print(A ^ A)
print(B ^ B)

Output result

{'e', 'a', 'b'}
{'e', 'a', 'b'}
