Python - Set Exercises

Python Set Exercise 1

Python program to find common elements in two lists with the help of set operations −

l1=[1,2,3,4,5]l2=[4,5,6,7,8]s1=set(l1)s2=set(l2)commons = s1&s2 # or s1.intersection(s2)commonlist = list(commons)print (commonlist)

It will produce the followingoutput −

[4, 5]

Python Set Exercise 2

Python program to check if a set is a subset of another −

s1={1,2,3,4,5}s2={4,5}if s2.issubset(s1):   print ("s2 is a subset of s1")else:   print ("s2 is not a subset of s1")

It will produce the followingoutput −

s2 is a subset of s1

Python Set Exercise 3

Python program to obtain a list of unique elements in a list −

T1 = (1, 9, 1, 6, 3, 4, 5, 1, 1, 2, 5, 6, 7, 8, 9, 2)s1 = set(T1)print (s1)

It will produce the followingoutput −

{1, 2, 3, 4, 5, 6, 7, 8, 9}
