Python Set issubset() Method

issuperset() in Python

Last Updated : 17 Aug, 2022

Python Set issuperset() method returns True if all elements of a set B are in set A. Then Set A is the superset of set B.

Python issuperset() Method Syntax:

Syntax: A.issuperset(B)

Parameter: Any other Set to compare with

Return: boolean value

Python issuperset() example

Example 1: Working of issubset() with two sets

Python3

A = {4, 1, 3, 5}
B = {6, 0, 4, 1, 5, 0, 3, 5}
 
print("A.issuperset(B) : ", A.issuperset(B))
print("B.issuperset(A) : ", B.issuperset(A))

Output:

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

Example 2: Working of Python issubset() Method with three Sets

Here we have use 3 different Sets to demonstrate the working of Python Set issubset() Method

Python

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

Python Set Methods

A Set in Python is a collection of unique elements which are unordered and mutable. Python provides various functions to work with Set. In this article, we will see a list of all the functions provided by Python to deal with Sets. Adding and Removing elementsWe can add and remove elements form the s

Set add() Method in Python

The set.add() method in Python adds a new element to a set while ensuring uniqueness. It prevents duplicates automatically and only allows immutable types like numbers, strings, or tuples. If the element already exists, the set remains unchanged, while mutable types like lists or dictionaries cannot

Python Set clear() Method

Python Set clear() method removes all elements from the set. Python Set clear() Method Syntax: Syntax: set.clear() parameters: The clear() method doesn't take any parameters. Return: None Time complexity : The time complexity of set.clear() function on a set with n element is O(n) . Example 1: Pytho

set copy() in python

The copy() method returns a shallow copy of the set in python. If we use "=" to copy a set to another set, when we modify in the copied set, the changes are also reflected in the original set. So we have to create a shallow copy of the set such that when we modify something in the copied set, change

Python Set discard() Function

Python discard() is a built-in method to remove elements from the set. The discard() method takes exactly one argument. This method does not return any value. Example: In this example, we are removing the integer 3 from the set with discard() in Python. C/C++ Code my_set = {1, 2, 3, 4, 5} my_set.dis

Python Set | difference_update()

The difference_update() method helps in an in-place way of differentiating the set. The previously discussed set difference() helps to find out the difference between two sets and returns a new set with the difference value, but the difference_update() updates the existing caller set.If A and B are

Python Set difference()

In Python, the difference() method is used to find elements that exist in one set but not in another. It returns a new set containing elements from the first set that are not present in the second set. This operation is similar to the subtraction of sets (A - B), where only unique elements from the

issuperset() in Python

Python Set issuperset() method returns True if all elements of a set B are in set A. Then Set A is the superset of set B.

Python Set issubset() Method

Python set issubset() method is used with sets to check whether all elements of one set are present in another set. It returns True if every element of the set is found in the other set otherwise, it returns False. Example: [GFGTABS] Python a = {1, 2, 3, 4, 5, 6} b = {4, 5, 6} res = a.issubset(b) pr

Python Set isdisjoint() Method

Python set isdisjoint() function check whether the two sets are disjoint or not, if it is disjoint then it returns True otherwise it will return False. Two sets are said to be disjoint when their intersection is null. Python set isdisjoint() Method Syntax: Syntax: set1.isdisjoint(set2) Parameters: a
