This code: 1. **Defines two lists `a` and `b`:** ...

This code:

1. Defines two lists a and b:

   • a = [1, 2, 3]
   • b = [2, 3, 4]

2. Converts the lists a and b to sets using set(a) and set(b).

   • This removes any potential duplicates and allows for set operations.

3. Finds the intersection of the two sets using set(a) & set(b):

   • The intersection (&) means it will return a set of elements that are common to both sets.

4. Assigns the result to c:

   • In this case, the intersection of {1, 2, 3} and {2, 3, 4} is {2, 3}.

So, the variable c is assigned the value {2, 3}, which is the set of elements common to both a and b.
