Question

what is the value of num when this loop completes?
num = 0
for i in range(2, 8, 2):
num = num + i

Explanation:

Step1: Analyze range function

The range(2, 8, 2) generates values \(2,4,6\).

Step2: Initialize num

num = 0 initially.

Step3: First iteration

When \(i = 2\), \(num=0 + 2=2\).

Step4: Second iteration

When \(i = 4\), \(num=2+4 = 6\).

Step5: Third iteration

When \(i = 6\), \(num=6 + 6=12\).

Answer:

12
