Python set isdisjoint() function check whether the two sets are disjoint or not, if it is disjoint then it returns True otherwise it will return False. Two sets are said to be disjoint when their intersection is null.
Python set isdisjoint() Method Syntax:
Syntax: set1.isdisjoint(set2)
Parameters:
- another set to compare with
or- an iterable (list, tuple, dictionary, and string)
Return: bool
Python Set isdisjoint() Method Example:
Python3
s1 = {1, 2, 3}s2 = {4, 5, 6}print(s1.isdisjoint(s2)) |
Output:
True
Example 1: Working with Set isdisjoint() Method
Python3
# Python3 program for isdisjoint() functionset1 = {2, 4, 5, 6}set2 = {7, 8, 9, 10}set3 = {1, 2}# checking of disjoint of two setsprint("set1 and set2 are disjoint?", set1.isdisjoint(set2))print("set1 and set3 are disjoint?", set1.isdisjoint(set3)) |
Output:
set1 and set2 are disjoint? True set1 and set3 are disjoint? False
Example 2: Python Set isdisjoint() with Other Iterables as arguments
Python3
# SetA = {2, 4, 5, 6}# Listlis = [1, 2, 3, 4, 5]# Dictionary dict, Set is formed on Keysdict = {1: 'Apple', 2: 'Orange'}# Dictionary dict2dict2 = {'Apple': 1, 'Orange': 2}print("Set A and List lis disjoint?", A.isdisjoint(lis))print("Set A and dict are disjoint?", A.isdisjoint(dict))print("Set A and dict2 are disjoint?", A.isdisjoint(dict2)) |
Output:
Set A and List lis disjoint? False Set A and dict are disjoint? False Set A and dict2 are disjoint? True
Example 3 : Both the sets are empty
Here we will see what will be the output if we use the isdisjoint() method with two sets both are empty.
Python3
# Python code to demonstrate# isdisjoint method with blank# sets# defining empty set1s1 = set()# defining empty set2s2 = set()# using the isdisjoint method # with empty setsprint(s1.isdisjoint(s2)) |
Output
True
