Python Set issuperset()

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

Superset of a Set
Superset of a Set

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.
