The issubset() method returns a bool value: True or False.
How to Use issubset() in Python
Example 1:
The issubset() method returns True if all elements of a set are present in another set (which could be equal to or larger than the original set). Otherwise, it returns False.
set1 = {1, 2, 3, 4}
set2 = {2, 4}
print(set2.issubset(set1)) # Output: True
Example 2:
The issubset() method can also be used to check if a set is a subset of another set.
set1 = {1, 2, 3, 4}
set2 = {2, 4}
print(set1.issubset(set2)) # Output: False
Example 3:
If there are elements in the set that are not present in the other set, issubset() returns False.
set1 = {1, 2, 3, 4}
set2 = {2, 4, 5}
print(set2.issubset(set1)) # Output: False
