Year 9 Computing — Blocks and indentation

1.Follow this code by hand. How many times does the most deeply indented line run?

for n in range(1, 5):
    print(n)
    if n > 100:
        print(n * 2)

2.The last line has been brought back out to the left. What is total at the end?

total = 0
for n in range(1, 4):
    total = total + 10
total = total + 1

3.This program prints four numbers. Put them in the order they appear on the screen.

total = 0
for n in range(1, 4):
    total = total + 5
    print(total)
print(total - 12)

• 15
• 5
• 10
• 3

4.Sort each line of this program by how many times it runs.

total = 0
for n in range(1, 4):
    total = total + n
    print(n)
print(total)
print(total * 2)

5.A test sits inside the loop here. What is total at the end?

total = 0
for n in range(1, 6):
    if n > 3:
        total = total + n

6.Both of the printing lines are indented here. How many numbers does it print?

for n in range(1, 4):
    print(n)
    print(99)

7.Follow this code by hand. What is count at the end?

count = 0
for n in range(1, 7):
    if n > 2:
        count = count + 1
    count = count + 10

8.One line is indented here and one is not. How many numbers does it print?

for n in range(1, 4):
    print(n)
print(99)
