02 Questions (10 items)
- FoundationA program sets a = 5 and b = 3, then prints a + b. What is the output?
- FoundationThe same program now prints a * b. What is the output?
- FoundationWhat do print(7 // 2) and print(7 % 2) output?
- IntermediateWhat is the output of print(2 ** 5)?
- IntermediateAfter input reads the string “12”, the program prints int(“12”) + 8. What is the output?
- IntermediateWhat is the output of print(“Hi” + “there”)?
- ChallengeWhat is the output of print(len(“Python”))?
- ChallengeHow many times does the loop for i in range(5) run?
- ChallengeWhat is the output of print(3 + 4 * 2)?
- Error redoError clinic: a student expects print(10 / 4) to give 2. What is the correct output?
03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 8 | The plus sign adds the two integers, so 5 plus 3 gives 8. |
| 2 | 15 | The star sign means multiply, so 5 times 3 gives 15. |
| 3 | 3 and 1 | Double slash keeps the whole-number part of the quotient, 3, and the percent sign gives the remainder, 1. |
| 4 | 32 | The double star means power, so 2 multiplied five times gives 32. |
| 5 | 20 | int converts the string to the integer 12, then adding 8 gives 20. |
| 6 | Hithere | The plus sign joins the two strings without inserting a space. |
| 7 | 6 | len counts the characters, and Python has six letters. |
| 8 | 5 times | range(5) produces the five numbers 0 to 4, so the loop runs five times. |
| 9 | 11 | Multiplication is done first, so 4 times 2 is 8 and adding 3 gives 11. |
| 10 | 2.5 | A single slash does true division and keeps the decimal, giving 2.5; use 10 // 4 for the whole part. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Write down the value of every variable line by line before stating the output. Remember input returns a string, so convert it with int before adding.Tutor Registration →
