Set Exercises

Python Set Exercise 1

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

Open Compiler

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 following output −

[4, 5]

Python Set Exercise 2

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

Open Compiler

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 following output −

s2 is a subset of s1

Python Set Exercise 3

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

Open Compiler

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 following output −

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