The given code performs the following actions: 1. **`a = [1,...

The given code performs the following actions:

1. a = [1, 2, 3]: Creates a list a containing the integers 1, 2, and 3.

2. b = [2, 3, 4]: Creates a list b containing the integers 2, 3, and 4.

3. set(a): Converts the list a into a set, yielding {1, 2, 3}. A set in Python is a collection of unique elements without duplicates.

4. set(b): Converts the list b into a set, yielding {2, 3, 4}.

5. set(a) & set(b): Performs a set intersection operation (&) between the two sets {1, 2, 3} and {2, 3, 4}. The intersection operation returns the common elements present in both sets, which are {2, 3}.

6. c = set(a) & set(b): Assigns the result of the intersection (common elements {2, 3}) to the variable c.

Final output of c: c will be a set containing the common elements between a and b, which is {2, 3}.

Summary:

The code finds the common elements between two lists a and b by converting them into sets and performing a set intersection.
