How do I check if a list is a subset of another list in Python using a loop?

To check if a list is a subset of another list in Python using a loop, you can follow these steps:
1. Define a function to check if one list is a subset of another:
- Create a function that takes two lists as arguments.
- Use a loop to iterate over each element in the first list.
- Check if each element is present in the second list.
- If any element is not found, returnFalse.
- If all elements are found, returnTrue.
- Example:
1
2
3
4
5
6
def is_subset(list1, list2):
for element in list1:
if element not in list2:
return False
return True
2. Use the function:
- Call theis_subset() function and pass the two lists you want to compare.
- It will returnTrue if the first list is a subset of the second list, andFalse otherwise.
- Example:
1
2
3
4
5
6
7
8
list1 = [1, 2, 3]
list2 = [1, 2, 3, 4, 5]
if is_subset(list1, list2):
print("List1 is a subset of List2")
else:
print("List1 is not a subset of List2")
By using a loop to iterate over each element in the first list and checking if it exists in the second list, you can efficiently determine if one list is a subset of another. This approach allows you to compare the elements of the lists sequentially, returningFalse as soon as a mismatch is found.
