The provided code performs the following steps: 1. **`a = [1,2,3]`**:...

The provided code performs the following steps:

1. a = [1,2,3]: Creates a list a containing the values [1, 2, 3].
2. b = [2,3,4]: Creates another list b containing the values [2, 3, 4].
3. c = set(a) & set(b):
   • Converts both a and b into sets (set(a) and set(b)), which are unordered collections of unique elements.
   • Performs a set intersection operation using the & operator. This operation calculates the elements that are common to both sets set(a) and set(b).

Result:

The variable c will contain the set of elements present in both a and b.

In this case:

• set(a) becomes {1, 2, 3}.
• set(b) becomes {2, 3, 4}.
• Their intersection (&) is {2, 3}.

So, the result of this code is:

• c = {2, 3}.

Summary:

The code creates two lists, converts them into sets, and computes the intersection to find common elements between the two lists. Finally, the common elements are stored in c as a set.
