How do I compare lists and sets in Python?

In Python, you can compare lists and sets using various methods. Lists are ordered and can contain duplicates, while sets are unordered and do not allow duplicates. Would you like to see examples?

Yes, please show me how to compare them.

Sure! You can use the == operator to compare lists directly. For sets, you can use the == operator as well, but it checks for equality of elements regardless of order. Here's a quick example:

list1 = [1, 2, 3]
list2 = [1, 2, 3]
set1 = {1, 2, 3}
set2 = {3, 2, 1}

print(list1 == list2)  # True
print(set1 == set2)    # True

What if I want to find the differences between them?

To find differences, you can use list comprehensions for lists and the difference() method for sets. For example:

list1 = [1, 2, 3, 4]
list2 = [3, 4, 5, 6]
set1 = {1, 2, 3, 4}
set2 = {3, 4, 5, 6}

list_diff = [item for item in list1 if item not in list2]
set_diff = set1.difference(set2)

print(list_diff)  # [1, 2]
print(set_diff)   # {1, 2}
