Given a set of elements p, the task is to write a Python program to convert the whole set into a list of Python Sets.

Example:

Input : p = {‘sky’, ‘is’, ‘blue’}

Output : [{‘blue’}, {‘is’}, {‘sky’}]

Explanation : Here each element of the set is converted into a individual set.

Input : p = {10, 20, 30, 40}

Output : [{10}, {20}, {30}, {40}]

Breaking a Set into a List of Sets Naive Approach

Here we have used a for-loop to iterate on all elements of the Set and create a new set for each item and append to the new list.

Python3




def los(l):
    res = []
     
    for i in l:
       
        # creating an empty set
        x = set()
        x.add(i)
        res.append(x)
         
    # returning final list of sets
    return(res)
 
 
# Driver code
lst = {'sky', 'is', 'blue'}
 
# Printing the final result
print(los(lst))


Output:

[{'sky'}, {'is'}, {'blue'}]

Breaking a Set into a List of Sets Using Python map() and lambda function

Here we have used lambda function and Python map() function to create a new set for each set item and create a list from it.

Python3




set1 = {1, 9, 8, 6, 5}
 
los = list(map(lambda x: {x}, set1))
print("List of set:", los)


Output:

List of set: [{1}, {5}, {6}, {8}, {9}]

Breaking a Set into a List of Sets Using List comprehension

Here we are using list comprehension and inside the list comprehension block, we are creating a new set. Thus, the result of the list comprehension will give a list of sets.

Python3




set1 = {1, 9, 8, 6, 5}
 
los = [{elem} for elem in set1]
print("List of set:", los)


Output:

List of set: [{1}, {5}, {6}, {8}, {9}]
