Python Set isdisjoint() method

Python Set isdisjoint() method

The set.isdisjoint() method in Python returns a boolean value True if two sets are disjoint sets ( i.e. none of the elements are present in both sets), otherwise it returns False.

Syntax

set.isdisjoint(set1)

Parameter

set- This parameter represents the main set.

set1- This argument signifies the other set to search for equal items.

Return

This method returns a boolean value True if two sets are disjoint sets, else it returns False.

Example 1

# Python program explaining
 # the set.isdisjoint() method
 #initializing set1
 set1 = {"mango", "banana", "apple","tomato"}
 print("Set 1:",set1) 
 # initializing set2
 set2 = {"potato", "spinach","Carrot", "apple"}
 print("Set 2:",set2)
 # will search for common items in both the sets,
 value= set1.isdisjoint(set2)  
 # will return false as the element "apple" is common in both sets
 print("The isdisjoint() method returns:",value) 

Output

Set 1: {'banana', 'tomato', 'apple', 'mango'}
Set 2: {'potato', 'apple', 'Carrot', 'spinach'}
The isdisjoint() method returns: False 

Example 2

# Python program explaining # the set.isdisjoint() method
# initializing set 1
set1 = {1,2,3, 4, 5, 9,10}   
# initializing set 2
set2 = {2,3,4,7, 8, 10}
# initializing set 3
set3 = {1,5,54} 
#checking of disjoint for set1 and set2  
# will return false, as there are common elements between set1 and set2
print("set1 and set2 are disjoint: ", set1.isdisjoint(set2)) 
 #checking of disjoint for set2 and set3  
# will return true as no common element between set2 and set3 
print("set2 and set3 are disjoint: ", set2.isdisjoint(set3))

Output

set1 and set2 are disjoint:  False
set2 and set3 are disjoint:  True
