how to check if a set is a subset of another set in python

To check if a set is a subset of another set in Python, you can use the issubset() method of sets. Here is an example:

main.py
set1 = {1, 2, 3, 4, 5}
set2 = {1, 3, 5}
set3 = {1, 3, 6}

print(set2.issubset(set1))  # True
print(set3.issubset(set1))  # False
129 chars
7 lines

In this example, set1 contains the elements 1, 2, 3, 4, and 5. set2 contains a subset of set1, namely 1, 3, and 5, so set2.issubset(set1) returns True. On the other hand, set3 contains an element (6) that is not in set1, so set3.issubset(set1) returns False.
