Use the difference() method to get the difference between two sets in Python. This method returns the difference between two sets which is also a set. It doesn’t modify the original sets.
A.difference(B)Example difference between two sets in Python
A simple example code gets the difference between two sets using the difference() between sets A and B.
The set difference between A and B is a set of elements that exist only in set A but not in B. For example:
A = {'A', 'B', 'C', 'D'}
B = {'C', 'F', 'X'}
# Equivalent to A-B
print(A.difference(B))
# Equivalent to B-A
print(B.difference(A))Output:
You can also find the set difference using - operator in Python.
A = {'A', 'B', 'C', 'D'}
B = {'C', 'F', 'X'}
print(A - B)
print(B - A)Output:
{‘D’, ‘A’, ‘B’}
{‘F’, ‘X’}
