How to create a Set of Sets in Python


How to create a Set of Sets in Python ?

Answer

To create a Set of Sets in Python, you can use sets to represent sets. You create individual sets as sets and then add them to another set.



✐ Examples

1 Creating a Set of Sets of Integers

In this example,

  1. First, we create three individual sets of integers named set1, set2, and set3. We add the elements 1, 2, 3 to set1, 4, 5, 6 to set2, and 7, 8, 9 to set3.
  2. Next, we create a set named setOfSets and add set1, set2, and set3 to it. This nests the three sets within a single set.
  3. We then iterate over each set within setOfSets using a for loop. Within the loop, we print each individual set to the standard output.

Python Program

set1 = {1, 2, 3}
set2 = {4, 5, 6}
set3 = {7, 8, 9}

setOfSets = {set1, set2, set3}

for set_ in setOfSets:
    print(set_)

Output

Output:
{1, 2, 3}
{4, 5, 6}
{8, 9, 7}

2 Creating a Set of Sets of Strings

In this example,

  1. First, we create three individual sets of strings named setA, setB, and setC. We add the elements "apple", "banana", "cherry" to setA, "dog", "elephant", "fox" to setB, and "grape", "honeydew", "kiwi" to setC.
  2. Next, we create a set named setOfStringSets and add setA, setB, and setC to it. This nests the three sets within a single set.
  3. We then iterate over each set within setOfStringSets using a for loop. Within the loop, we print each individual set to the standard output.

Python Program

setA = {'apple', 'banana', 'cherry'}
setB = {'dog', 'elephant', 'fox'}
setC = {'grape', 'honeydew', 'kiwi'}

setOfStringSets = {setA, setB, setC}

for set_ in setOfStringSets:
    print(set_)

Output

Output:
{'banana', 'cherry', 'apple'}
{'fox', 'elephant', 'dog'}
{'kiwi', 'grape', 'honeydew'}
