How to create a List of Sets in Python

How to create a List of Sets in Python ?

In Python, you can create a list of sets using the list comprehension for the outer list and the set constructor for the inner sets.

In this example,

We create two inner sets named set1 and set2 using the set constructor.
We create an outer list named list_of_sets using list comprehension and initialize it with the inner sets.
Finally, we iterate through the list of sets and print each set to standard output.

set1 = {1, 2, 3}
set2 = {'a', 'b', 'c'}

list_of_sets = [set1, set2]

for s in list_of_sets:
    print(s)

{1, 2, 3}
{'a', 'b', 'c'}

In this example,

We create an empty outer list named list_of_empty_sets using list comprehension.
We add two empty sets to the outer list using the set constructor.
Finally, we iterate through the list of sets with empty inner sets and print each set to standard output.

list_of_empty_sets = [set(), set()]

for s in list_of_empty_sets:
    print(s)

set()
set()

In this tutorial, we learned How to create a List of Sets in Python language with well detailed examples.
