Python Set issuperset() Method

Determines whether all items in the specified set are present in the original set

Usage

The issuperset() method returns True if all items in the specified set are present in the original set, otherwise FALSE.

Syntax

set.issuperset(set)

Basic Example

# Check if all items in B are present in A
A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A.issuperset(B))
# Prints True

Equivalent Operator >=

You can achieve the same result by using the >= comparison operator.

A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A >= B)
# Prints True

Find Proper Superset

To test whether the set is a proper superset of other, use > comparison operator.

# Check if A is a proper superset of B
A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A > B)
# Prints True

# Check if A is a proper superset of B
A = {'yellow', 'red'}
B = {'yellow', 'red'}
print(A > B)
# Prints False
