Question types: What does it print?

Rule: What does the program print? (Python)

Run the program line by line and write down the variables. x = x + 3 means: add 3 to x.

range(1, 5) gives 1, 2, 3, 4 but not 5. // is whole-number division, % the remainder.

Example: s = 0, then for i in range(1, 4): s = s + i → 1 + 2 + 3, it prints 6

Watch out: range(1, 5) never reaches 5: the loop runs 4 times, not 5.

Sample questions

Question 1 Easy

Answer: 32

How it works: Values of b: 8 → 32. The program prints 32.
Question 2 Normal

Answer: 27

How it works: Values of p: 1 → 3 → 9 → 27. The program prints 27.
Question 3 Hard

What does this program print?
```
s = 0
for i in range(1, 9):
    if i % 2 == 0:
        s = s + i
    else:
        s = s - 1
print(s)
```
Show the solution

Answer: 16

How it works: Values of s: 0 → −1 → 1 → 0 → 4 → 3 → 9 → 8 → 16. The program prints 16.
