# 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 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:-

Enter number of elements of list: 3

Enter element: 4

Enter element: 3

Enter element: 7

Subsets:

[[], [7], [4], [4, 7], [3], [3, 7], [3, 4], [3, 4, 7]]

Enter element: 4

Enter element: 3

Enter element: 7

Subsets:

[[], [7], [4], [4, 7], [3], [3, 7], [3, 4], [3, 4, 7]]

**Program Explanation**

- 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.
