# issuperset() in Python

• Difficulty Level : Easy
• Last Updated : 05 Feb, 2018

The issuperset() method returns True if all elements of a set A occupies set B which is passed as an argument and returns false if all elements of B not present in A.
This means if A is a superset of B then it returns true; else False

Syntax:

```A.issuperset(B)
checks whether A is a superset of B or not.```

Returns:

`True if A is a superset of B; otherwise false.` Code 1:

 `# Python program to demonstrate working of``# issuperset().`` ` `A ``=` `{``4``, ``1``, ``3``, ``5``}``B ``=` `{``6``, ``0``, ``4``, ``1``, ``5``, ``0``, ``3``, ``5``}`` ` `print``(``"A.issuperset(B) : "``, A.issuperset(B))`` ` `# B is superset of A``print``(``"B.issuperset(A) : "``, B.issuperset(A))`

Output:

```A.issuperset(B) :  False
B.issuperset(A) :  True
```

Code 2:

 `# Python program to demonstrate working ``# of issuperset().`` ` `A ``=` `{``1``, ``2``, ``3``}``B ``=` `{``1``, ``2``, ``3``, ``4``, ``5``}``C ``=` `{``1``, ``2``, ``4``, ``5``}`` ` `print``(``"A.issuperset(B) : "``, A.issuperset(B))`` ` `print``(``"B.issuperset(A) : "``, B.issuperset(A))`` ` `print``(``"A.issuperset(C) : "``, A.issuperset(C))`` ` `print``(``"C.issuperset(B) : "``, C.issuperset(B))`

Output:

```A.issuperset(B) :  False
B.issuperset(A) :  True
A.issuperset(C) :  False
C.issuperset(B) :  False```
