Supersets in Python programming language

In Python programming, a superset is a set that includes all the elements of another set. Python allows us to create supersets easily with its built-in set data type. Supersets can be useful in many scenarios, such as data manipulation, data analysis, and algorithmic problem-solving. In this tutorial, we will explore the concept of supersets in Python programming. We will cover how to define and create supersets, perform operations on supersets, and also demonstrate some common use cases where supersets can be particularly helpful. This tutorial assumes some prior knowledge of Python programming and set operations.

What is a Superset :

• If all the elements of  set_2  are also present in  set_1 then  set_1 is called a superset of  set_2  .
• If  set_1 is not equal to  set_2  then  set_1 is called a proper superset of  set_2  .
• A set is also a superset of itself.
• In Python we can find if one set is a superset of another by using the : 
  • issuperset() method
  • superset operator '>='
  • proper superset operator '>'

using issuperset() method :

• This built-in method  issuperset()  can be used to check if a set is a superset of another or not.
• The basic syntax of using the  issuperset()  method is :  bool_value = set_1.issuperset(set_2) 
• The  issuperset()  method returns a boolean value :
  • True if  set_1 is a superset of  set_2  
  • False if  set_1 is not a superset of  set_2  
• Code Sample : 

set_1 = {1, 2, 3}
set_2 = {1, 2, 3, 4, 5, 6, 7}
val = set_2.issuperset(set_1)

print(f"Value of set_1 = {set_1}")
print(f"Value of set_2 = {set_2}")
print(f"set_2 is superset of set_1 = {val}")

# Output
# Value of set_1 = {1, 2, 3}
# Value of set_2 = {1, 2, 3, 4, 5, 6, 7}
# set_2 is superset of set_1 = True

using the superset operator '>=' :

• The superset operator  >=  can be used to check if a set is a superset of another or not.
• The basic syntax of using superset operator is :  set_1 >= set_2 
• The superset operator returns a boolean value :
  • True if  set_1 is a superset of  set_2  
  • False if  set_1 is not a superset of  set_2  
• Code Sample : 

set_1 = {1, 2, 3}
set_2 = {1, 2, 3, 4, 5, 6, 7}
val = set_2 >= set_1

print(f"Value of set_1 = {set_1}")
print(f"Value of set_2 = {set_2}")
print(f"set_2 is superset of set_1 = {val}")

# Output
# Value of set_1 = {1, 2, 3}
# Value of set_2 = {1, 2, 3, 4, 5, 6, 7}
# set_2 is superset of set_1 = True

using the proper superset operator '>' :

• The proper superset operator   >  can be used to check if a set is a proper superset of another or not.
• The basic syntax of using proper superset operator is :  set_1 > set_2 
• The proper superset operator returns a boolean value :
  • True if  set_1 is a proper superset of  set_2  
  • False if  set_1 is not a proper superset of  set_2  
• Code Sample : 

set_1 = {1, 2, 3}
set_2 = {1, 2, 3, 4, 5, 6, 7}
val = set_2 > set_1

print(f"Value of set_1 = {set_1}")
print(f"Value of set_2 = {set_2}")
print(f"set_2 is proper superset of set_1 = {val}")

# Output
# Value of set_1 = {1, 2, 3}
# Value of set_2 = {1, 2, 3, 4, 5, 6, 7}
# set_2 is proper superset of set_1 = True
