How do I check if a list is a superset of another list in Python using the issuperset() method?

To check if a list is a superset of another list in Python using theissuperset() method, you can follow these steps:
1. Define the two lists to be compared:
1
2
3
4
list1 = [1, 2, 3, 4, 5]
list2 = [2, 4, 5]
2. Use theissuperset() method to check iflist1 is a superset oflist2:
1
2
3
4
5
6
if set(list1).issuperset(list2):
print("list1 is a superset of list2")
else:
print("list1 is not a superset of list2")
In this example, theissuperset() method is used to comparelist1 andlist2. Theset() function is used to convert the lists to sets, as theissuperset() method operates on sets. Theissuperset() method returnsTrue iflist1 contains all the elements inlist2 and may have additional elements. Otherwise, it returnsFalse.
Theissuperset() method performs a set-based comparison, disregarding the order of elements in the lists. It only considers the presence or absence of elements.
Iflist1 is a superset oflist2, meaning thatlist1 contains all the elements inlist2, the program will output "list1 is a superset of list2". Otherwise, it will output "list1 is not a superset of list2".
Using theissuperset() method is a straightforward way to check if a list is a superset of another list in Python.
