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

The given code performs the following actions:

1. a = [1,2,3]: This initializes a list a with the elements [1, 2, 3].
2. b = [2,3,4]: This initializes another list b with the elements [2, 3, 4].
3. c = set(a) & set(b):
   • set(a) converts the list a into a set, which would be {1, 2, 3}.
   • set(b) converts the list b into a set, which would be {2, 3, 4}.
   • The & operator is the set intersection operator, which computes the common elements between the two sets.
   • The result of the intersection operation (set(a) & set(b)) would be {2, 3}, as these are the elements common to both a and b.

At the end, the variable c will hold the value {2, 3} which is a set containing the common elements between a and b.
