Python Set issuperset() Method

The Python set issuperset() method returns True if a set contains all elements of another set, and False otherwise. It can also be written using the >= operator.

The syntax of the issuperset() method is:

set.issuperset(set2)
# or
set1 >= set2

Python set issuperset() Parameters

The issuperset() method takes one parameter:

• set2: Another set or iterable to check if the original set is its superset.

Here are examples demonstrating the issuperset() method:

# Example 1: Basic superset check
set1 = {1, 2, 3, 4, 5}
set2 = {2, 3, 4}
result = set1.issuperset(set2)
print(result)  # Output: True

# Example 2: Using operator syntax
numbers1 = {1, 2, 3}
numbers2 = {1, 2}
result = numbers1 >= numbers2
print(result)  # Output: True

# Example 3: Equal sets are supersets
set1 = {1, 2, 3}
set2 = {1, 2, 3}
result = set1.issuperset(set2)
print(result)  # Output: True

The issuperset() method is useful for checking if one set contains another set entirely.
