If setA = {1, 2, 3} and setB = {3, 4, 5}. What will be the elements in setA after executing setA.update(setB)?{1,2,3,4,5}{4,5}{3}{1, 2}

To determine the elements in setA after executing setA.update(setB), let's break down the problem.

1. Break Down the Problem

• We have two sets:
  $\text{setA} = \{1, 2, 3\}$
  $\text{setB} = \{3, 4, 5\}$
• We need to analyze what happens to setA after the update() method is called with setB as an argument.

2. Relevant Concepts

• The update() method in Python sets adds all elements from setB to setA. If some elements in setB already exist in setA, they will not be added again (as sets do not allow duplicate values).

3. Analysis and Detail

• Before update:
  $\text{setA} = \{1, 2, 3\}$
  $\text{setB} = \{3, 4, 5\}$

• When setA.update(setB) is executed:

  • The element 3 is already present in setA.
  • The elements 4 and 5 will be added to setA.

• Therefore, after the update, setA will contain:
  $\text{setA} = \{1, 2, 3, 4, 5\}$

4. Verify and Summarize

• After executing the update operation, we confirm that $\text{setA}$ now contains all unique values from both sets. The duplicates are omitted.

Final Answer

The elements in setA after executing setA.update(setB) will be $\{1, 2, 3, 4, 5\}$.
