The answer is D. The program prints:
9
Why?
range(0, 8, 3) starts at 0, goes up in steps of 3, and stops before 8. So the loop adds 0 + 3 + 6. The total is 9.
Trace table
A trace table follows the program step by step. Here’s this one:
| number | total after the loop body |
|---|---|
| 0 | 0 |
| 3 | 3 |
| 6 | 9 |
The code again
total = 0
for number in range(0, 8, 3):
total = total + number
print(total)Try it: change one number in the program and predict the new output before you run it.
