The isdisjoint() method returns True if two sets are disjoint sets. If not, it returns False.
Two sets are said to be disjoint sets if they have no common elements. For example:
A = {1, 5, 9, 0} B = {2, 4, -5}
Here, sets A and B are disjoint sets.

The syntax of isdisjoint()
is:
set_a.isdisjoint(set_b)
1. isdisjoint() Parameters
isdisjoint()
method takes a single argument (a set).
You can also pass an iterable (list, tuple, dictionary, and string) to disjoint()
. isdisjoint()
method will automatically convert iterables to set and checks whether the sets are disjoint or not.
2. Return Value from isdisjoint()
isdisjoint()
method returns
True
if two sets are disjoint sets (if set_a and set_b are disjoint sets in above syntax)False
if two sets are not disjoint sets
3. Example 1: How isdisjoint() works?
A = {1, 2, 3, 4} B = {5, 6, 7} C = {4, 5, 6} print('Are A and B disjoint?', A.isdisjoint(B)) print('Are A and C disjoint?', A.isdisjoint(C))
Output
Are A and B disjoint? True Are A and C disjoint? False
4. Example 2: isdisjoint() with Other Iterables as arguments
A = {'a', 'b', 'c', 'd'} B = ['b', 'e', 'f'] C = '5de4' D ={1 : 'a', 2 : 'b'} E ={'a' : 1, 'b' : 2} print('Are A and B disjoint?', A.isdisjoint(B)) print('Are A and C disjoint?', A.isdisjoint(C)) print('Are A and D disjoint?', A.isdisjoint(D)) print('Are A and E disjoint?', A.isdisjoint(E))
Output
Are A and B disjoint? False Are A and C disjoint? False Are A and D disjoint? True Are A and E disjoint? False
