The given code performs the following operations: 1. `a = [1,2,3]`:...

The given code performs the following operations:

1. a = [1,2,3]: This creates a list a with the elements [1, 2, 3].

2. b = [2,3,4]: This creates another list b with the elements [2, 3, 4].

3. c = set(a) & set(b):

   • First, set(a) converts the list a into a set, which will be {1, 2, 3}.
   • Similarly, set(b) converts the list b into a set, which will be {2, 3, 4}.
   • The & operator finds the intersection of the two sets, which is the set of elements common to both set(a) and set(b).

As a result, c will be the set {2, 3}, containing the common elements from both lists.

So, this code identifies the common elements between the two lists and stores them in the set c.
