The answer is B. The program prints:
15

Why?
range(2, 10, 3) starts at 2, goes up in steps of 3, and stops before 10. So the loop adds 2 + 5 + 8. The total is 15.
Trace table
A trace table follows the program step by step. Here’s this one:
| number | total after the loop body |
|---|---|
| 2 | 2 |
| 5 | 7 |
| 8 | 15 |
The code again
total = 0
for number in range(2, 10, 3):
total = total + number
print(total)
Try it: change one number in the program and predict the new output before you run it.
