1. Overview
The issuperset() method returns True if a set has every elements of another set (passed as an argument). If not, it returns False.
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.
2. Return Value from issuperset()
issuperset() returns
- True if A is a superset of B
- False if A is not a superset of B
3. 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.
