Week 5 Quiz

The reading log starts at 45 pages, aims for 300, and adds 30 pages a day. What do the two print lines show?

goal = 300
pages_read = 45
days = 0
while pages_read < goal:
    pages_read = pages_read + 30
    days = days + 1
print(days)
print(pages_read)

Select one.

• 8, then 285
• 9, then 300
• 9, then 315
• 10, then 345

Predict the counter's final value. What does the last line print?

count = 1
while count <= 5:
    count = count + 1
print(count)

Select one.

• 4
• 5
• 7
• 6

The body adds 1 and then prints. What does this program print?

count = 3
while count < 5:
    count = count + 1
    print(count)

Select one.

• 4 only
• 4, then 5
• 3, then 4
• 4, then 5, then 6

How many lines does the loop body print before the loop ends?

count = 1
while count < 5:
    print(count)
    count += 1

Select one.

• 4
• 5
• 3
• 6

The accumulator total collects each value of n. What does the last line print?

total = 0
n = 1
while n <= 5:
    total += n
    n += 1
print(total)

Select one.

• 10
• 15
• 21
• 5

This loop looks for the first whole number whose square is greater than 50. What does it print?

n = 1
while True:
    if n * n > 50:
        print(n)
        break
    n = n + 1

Select one.

• 7
• 49
• 64
• 8

This loop was meant to print 1 to 5. Select every statement that is true about it.

count = 1
while count <= 5:
    print(count)

Select every option that applies.

• It prints 1 again and again and never stops on its own.
• It prints 1 to 5 and then stops.
• Pressing Ctrl+C in a terminal, or the Stop button in a browser runner, ends the run.
• Adding count += 1 as the last line of the body makes it print 1 to 5 and stop.
• Python refuses to run it and reports a SyntaxError.

After 8 passes of the reading-log loop, pages_read holds 285. At the top of the next pass Python evaluates the condition pages_read < goal with goal at 300. What happens?

Select one.

• The condition is True, so the ninth pass runs.
• The condition is False, so the loop ends at 285.
• The condition is True, but the loop stops at 300.
• The condition is False, so the loop ends at 300.

In the condition count <= 5, the comparison produces True when count is 5.

True or false.

• True
• False

A loop meant to print the numbers 1 to 5 prints only 1 to 4. Which single change makes it print 1 to 5?

count = 1
while count < 5:
    print(count)
    count += 1

Select one.

• Move print(count) below count += 1.
• Change count += 1 to count += 2.
• Change < to <= in the while line.
• Add break after print(count).
