Examine the following Python code. What will be printed if the user enters 'ten' when prompted?

try:
num = int(input('Enter a number: '))
print('Double is', num * 2)
except ValueError:
print('That is not a valid integer')
except:
print('An unexpected error occurred')

Q: How do I try a free CIE Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Examine the following Python code. What will be printed if the user enters 'ten' when prompted?

try:
    num = int(input('Enter a number: '))
    print('Double is', num * 2)
except ValueError:
    print('That is not a valid integer')
except:
    print('An unexpected error occurred')

Accepted Answer

That is not a valid integer — Entering 'ten' causes int() to raise a ValueError because 'ten' cannot be converted to an integer. The first except clause specifically catches ValueError and prints 'That is not a valid integer'. The second general except clause is not reached because ValueError was already matched. 'Double is ten' would require no conversion; 'Double is 20' assumes numeric input.

Answer

Double is 20

Answer

Double is ten

Answer

That is not a valid integer

Answer

An unexpected error occurred
