The answer is D. The program prints:
34
Why?
range(4, 14, 3) starts at 4, goes up in steps of 3, and stops before 14. So the loop adds 4 + 7 + 10 + 13. The total is 34.
Trace table
A trace table follows the program step by step. Here’s this one:
| number | total after the loop body |
|---|---|
| 4 | 4 |
| 7 | 11 |
| 10 | 21 |
| 13 | 34 |
The code again
total = 0
for number in range(4, 14, 3):
total = total + number
print(total)Try it: change one number in the program and predict the new output before you run it.
