Python Set issuperset()

Set X is said to be the superset of set Y if all elements of Y are in X.

Here, set B is a superset of set A and A is a subset of set B.

The syntax of issuperset() is:

 A.issuperset(B)

The following code checks if A is a superset of B.

Return Value from issuperset()

issuperset() returns

• True if A is a superset of B
• False if A is not a superset of B

Example: How issuperset() works?

 A = {1, 2, 3, 4, 5} B = {1, 2, 3} C = {1, 2, 3} # Returns True print(A.issuperset(B)) # Returns False print(B.issuperset(A)) # Returns True print(C.issuperset(B))

Output

 True False True

If you need to check if a set is a subset of another set, you can use issubset() in Python.
