How Can I Find the Intersection of Two Lists in Python?

Accessing List Intersections

To retrieve the intersection of two lists, commonly referred to as a boolean AND operation, there are various approaches. One straightforward method is to utilize set intersection. This approach disregards order and duplicates, ensuring that only common elements are included in the result.

To employ this technique, begin by converting the lists to sets using the set() function. Then, perform a set intersection operation using the & operator. Finally, convert the resulting set back to a list using the list() function. This process yields a list containing only the elements present in both the original lists.

Consider the following example:

a = [1,2,3,4,5]
b = [1,3,5,6]
c = list(set(a) & set(b))
print(c)

The expected output for this code is:

[1, 3, 5]
