Question

What is the value of num when this loop completes?

num = 0
for i in range(2, 8, 2):
num = num + i

Answer 1

The loop in the Python code snippet adds the sequence 2, 4, 6 to an initial value of 0. By the end of the loop, the value of num is 12.

Step-by-step explanation:

The question asks about the final value of num after execution of a loop in a Python program.

The provided code snippet uses a for loop that iterates over a range of numbers. Here's the breakdown:

• The range starts at 2 and ends before 8, incrementing by 2 each time.
• Thus, the loop iterates through the sequence 2, 4, 6.
• Each iteration adds the current value of i to num which starts at 0.

Calculating the sum: 0 + 2 + 4 + 6 = 12

Therefore, the value of num when the loop completes is 12.
