Python Program to Create a Class and Get All Possible Subsets from a Set of Distinct Integers

In this example, we will write a python program to create a class and get all possible subsets from a set of distinct integers. To better understand this example, make sure you have knowledge of the following tutorials:-

• Python Class and Objects
• Python Constructor
• Python Functions

Python Program to Convert temperatures using Classes

class Subset:
    def f1(self, s1):
        return self.f2([], sorted(s1))

    def f2(self, curr, s1):
        if s1:
            return self.f2(curr, s1[1:]) + self.f2(curr + [s1[0]], s1[1:])
        return [curr]


a = []
n = int(input("Enter number of elements of list: "))
for i in range(0, n):
    b = int(input("Enter element: "))
    a.append(b)
print("Subsets: ")
print(Subset().f1(a))

The output of the above program is:-

• A class named “Subset” is defined that has two methods f1 and f2.
• The number of elements is taken from the user and using a for loop, the elements of the list are taken.
• The f1 method of the class is called passing the list as a parameter.
• The f2 method is a recursive function that generates all the sublist until the list becomes empty.
• The final result is printed.
