Sets Python Program

Python Lab Manual / Sets Python Program

Program Name

Write a Python Sets Program.

Theory

Sets are used to store collections of data / items which is unordered and unindexed.

Program Code


# Creating two sets
print("Creating two setsy")
set1 = set() 
print("Set1 = ", set1) 


#Adding elements to set2 
print("\nAdding elements to set")
set2 = set() 
for i in range(3, 8): 
	set2.add(i) 
print("Set2 = ", set2) 



# Union of set1 and set2 
print("\nUnion of sets")
set1 = set() 
for i in range(2, 4): 
	set1.add(i)  
set3 = set1.union(set2) 
print("Union of Set1 & Set2: Set3 = ", set3) 


#Intersection of set1 and set2 
print("\nIntersection of sets")
set4 = set1.intersection(set2) 
print("Intersection of Set1 & Set2: Set4 = ", set4) 


#Checking relation between sets 
print("\nChecking relation between sets") 
if set1 > set2:        # set1.issuperset(set2) 
	print("Set1 is superset of Set2") 
elif set1< set2:     # set1.issubset(set2) 
	print("Set1 is subset of Set2") 
elif set1 == set2 : 
	print("Set1 is same as Set2")
else: print("Set1 is same as Set2")


# difference between set1 and set2
print("\nDiference between set1 and set2")
set5 = set1 - set2 
print("Set1 - Set2 = set5 = ", set5) 
print("\n") 


#check if for sets are disjoint or not
print("\ncheck if for sets are disjoint or not")
if set4.isdisjoint(set5):  
	print("\nsets are disjoint") 
else:
	print("\nsets are not  disjoint") 
	
	
#Removing all the values of set5 
print("\nRemoving all the values of set5 ") 
set5.clear() 
print("Set5 = ", set5)

Input and Output:

Output:
Creating two setsy
Set1 =  set()

Adding elements to set
Set2 =  {3, 4, 5, 6, 7}

Union of sets
Union of Set1 & Set2: Set3 =  {2, 3, 4, 5, 6, 7}

Intersection of sets
Intersection of Set1 & Set2: Set4 =  {3}

Checking relation between sets
Set1 is same as Set2

Diference between set1 and set2
Set1 - Set2 = set5 =  {2}

check if for sets are disjoint or not
sets are disjoint

Removing all the values of set5 
Set5 =  set()
