The given Python code snippet does the following: 1. **`a =...

The given Python code snippet does the following:

1. a = [1, 2, 3] and b = [2, 3, 4]:
   Two lists a and b are created. a contains the integers [1, 2, 3], and b contains [2, 3, 4].

2. set(a) and set(b):
   The set() function converts the lists a and b into sets. Sets are unordered collections of unique elements. So, set(a) becomes {1, 2, 3} and set(b) becomes {2, 3, 4}.

3. set(a) & set(b):
   The & operator, when used between two sets, performs a set intersection. The intersection of two sets includes only the elements present in both sets. For set(a) = {1, 2, 3} and set(b) = {2, 3, 4}, the intersection is {2, 3}.

4. c = set(a) & set(b):
   The result of the set intersection ({2, 3}) is stored in the variable c.

Final Output:

c will contain the set {2, 3}, which represents the common elements between the two lists a and b.
