Chapter 9: Problem 28

After the following code executes, what elements will be members of set3? set1 = set([1, 2, 3, 4]) set2 = set([3, 4, 5, 6]) set3 = set1.intersection(set2)

Short Answer

Expert verified

Answer: Set3 will contain the elements 3 and 4.

Step by step solution

Understand the intersection of sets

The intersection of two sets is the set containing all the elements that are common to both sets. In other words, an element will be in the intersection of set1 and set2 if it is present in both set1 and set2.

Analyze set1 and set2

Before finding the intersection, let's examine the given sets. set1 = {1, 2, 3, 4} set2 = {3, 4, 5, 6}

Find the intersection of set1 and set2

To find the intersection of set1 and set2, we will go through each element in set1 and check if it is also in set2. If it is, we will include it in set3. - Compare 1 in set1 to the elements in set2: 1 is not present in set2, so it's not in the intersection. - Compare 2 in set1 to the elements in set2: 2 is not present in set2, so it's not in the intersection. - Compare 3 in set1 to the elements in set2: 3 is present in set2, so it's in the intersection. - Compare 4 in set1 to the elements in set2: 4 is present in set2, so it's in the intersection.

Create set3 containing the intersection elements

Now that we have identified the elements in the intersection (3 and 4), we can create set3 containing these elements. set3 = {3, 4} So, after the given code executes, set3 will have the elements 3 and 4 as its members.
