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```
