Set “difference()” method:

• The Python set is used to create the unordered collection of unique objects.

• The built-in “set()” function is used in Python to create the sets.

• The set difference operation is used to find the elements in a set that is not present in another set.

• The “difference ()” method in Python is used to perform the set difference operation between sets.

Syntax:

In Python, the “difference ()” method can be used to find the set difference of sets as follows:

set1.difference (set2)

Program:

#create the set set1 with three character type members

set1 = set(['d', 'e', 'f'])

#create the set set2 with five character type members

set2 = set(['a', 'b', 'c', 'd', 'e'])

#find the difference of set1 from set2

set3 = set1.difference(set2)

#display the difference set set3

print(set3)

Explanation of the program:

In the above Python program,

• The first statement is to create the set “set1” with elements “d”, “e”, and “f”...
