Set isdisjoint() Method

isdisjoint() method is used to check whether elements are common in two sets or not, method is called with one set (commonly known as this set) and another set is supplied as an argument, method returns "True" if none of the elements are common in both sets, else it returns "False".

Syntax:

    set1.isdisjoint(set2)

Parameter(s):

  • set1 – It represents the set1 (this set).
  • set2 – It represents the set2 (another set to be compared).

Return value:

The return type of this method is <class 'bool'>, it returns a Boolean value (True or False).

Example 1:

# Python Set isdisjoint() Method with Example

# declaring the sets
cars_1 = {"Porsche", "Audi", "Lexus"}
cars_2 = {"Porsche", "Mazda", "Lincoln"}
cars_3 = {"BMW", "Mazda", "Lincoln"}

# isdisjoint() method call
result = cars_1.isdisjoint(cars_2)
print("cars_1.isdisjoint(cars_2): ", result)

result = cars_2.isdisjoint(cars_3)
print("cars_2.isdisjoint(cars_3): ", result)

result = cars_1.isdisjoint(cars_3)
print("cars_1.isdisjoint(cars_3): ", result)

Output

cars_1.isdisjoint(cars_2):  False
cars_2.isdisjoint(cars_3):  False
cars_1.isdisjoint(cars_3):  True

Example 2:

# Python Set isdisjoint() Method with Example

# declaring the sets
x = {"ABC", "PQR", "XYZ"}
y = {"ABC", "PQR", "XYZ"}
z = {"DEF", "MNO", "UVW"}

# isdisjoint() method calls
result = x.isdisjoint(y)
print("x.isdisjoint(y): ", result)

result = y.isdisjoint(z)
print("y.isdisjoint(z): ", result)

result = z.isdisjoint(x)
print("z.isdisjoint(x): ", result)

result = x.isdisjoint(z)
print("x.isdisjoint(z): ", result)

result = y.isdisjoint(x)
print("y.isdisjoint(x): ", result)

Output

x.isdisjoint(y):  False
y.isdisjoint(z):  True
z.isdisjoint(x):  True
x.isdisjoint(z):  True
y.isdisjoint(x):  False
