To check if a list is a superset of another list in Python using set operations, you can follow these steps: 1. Convert lists to sets: - Start by converting both lists to sets using theset() function. - Sets are unordered collections of unique elements, which allow us to perform set operations like subset and superset checks. - Example:

1
2
3
4
5
6

list1 = [1, 2, 3, 4, 5]
list2 = [3, 4]

set1 = set(list1)
set2 = set(list2)

2. Check for superset: - Use theissuperset() method to check ifset1 is a superset ofset2. - Theissuperset() method returnsTrue ifset1 contains all elements ofset2, making it a superset. - Example:

1
2
3
4
5

def is_superset(list1, list2):
set1 = set(list1)
set2 = set(list2)
return set1.issuperset(set2)

3. Use the function: - Call theis_superset() function and pass the lists you want to compare. - It will returnTrue iflist1 is a superset oflist2, andFalse otherwise. - Example:

1
2
3
4
5
6
7
8

list1 = [1, 2, 3, 4, 5]
list2 = [3, 4]

if is_superset(list1, list2):
print("list1 is a superset of list2")
else:
print("list1 is not a superset of list2")

By converting the lists to sets and using theissuperset() method, you can efficiently check if one list is a superset of another. This approach leverages the set operations provided by Python to perform the comparison and determine if one set contains all elements of another.
