The answer is D. The program prints:
38
Why?
range(5, 15, 3) starts at 5, goes up in steps of 3, and stops before 15. So the loop adds 5 + 8 + 11 + 14. The total is 38.
Trace table
A trace table follows the program step by step. Here’s this one:
| number | total after the loop body |
|---|---|
| 5 | 5 |
| 8 | 13 |
| 11 | 24 |
| 14 | 38 |
The code again
total = 0
for number in range(5, 15, 3):
total = total + number
print(total)Try it: change one number in the program and predict the new output before you run it.
