The difference method
The difference method returns a set obtained from the elements by which the first set differs from the second. In the parameter, we specify the set with which we want to compare the original.
Syntax
set.difference(the set we want to compare with)
Example
Let's apply the difference method to get the different elements of two sets:
st1 = {'a', 'b', 'c'}
st2 = {'e', 'g', 'a'}
res = st1.difference(st2)
print(res)
Result of code execution:
{'c', 'b'}
Example
The difference method also has a short form:
st1 = {'a', 'b', 'c'}
st2 = {'e', 'g', 'a'}
res = st1 - st2
print(res)
Result of code execution:
{'b', 'c'}
