This Python code finds the intersection of two lists a and b by converting them into sets and performing a set intersection.

• a = [1,2,3]: This creates a list a with the elements [1, 2, 3].
• b = [2,3,4]: This creates a list b with the elements [2, 3, 4].
• set(a) converts the list a into a set {1, 2, 3}.
• set(b) converts the list b into a set {2, 3, 4}.
• set(a) & set(b) computes the intersection of the two sets, resulting in {2, 3}, which contains the common elements between a and b.

Finally, the result {2, 3} is assigned to the variable c.
