• Difficulty Level : Easy
• Last Updated : 05 Oct, 2021

Python set 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 are not present in A. This means if A is a superset of B then it returns true; else False

### Python issuperset() Syntax:

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

### Python issuperset() Returns:

`True if A is a superset of B; otherwise false.` ## Python

 `# 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```

Output:

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