1. Which comment correctly credits reused code?

A # Source: https://example.com/sort, Jo Lin, MIT licence

B # sorting code

2. Where should the # Source: comment go?

A Hidden at the very end of the file

B Directly above the reused code

3. You copy a function from a tutorial website. What should you do?

A Add a comment with the URL, author and licence

B Delete the URL so the code looks like yours

4. Which detail is MISSING from this comment? # Source: https://example.com/timer

A The author and the licence

B The programming language

5. Why do you mark which lines are not your own?

A So the computer runs the reused lines faster

B So your teacher can see which code you wrote and which you reused

Answer Key

Crediting code from other sources in comments

Section A: Quick Questions

A — # Source: https://example.com/sort, Jo Lin, MIT licence

B — Directly above the reused code

A — Add a comment with the URL, author and licence

A — The author and the licence

B — So your teacher can see which code you wrote and which you reused

Section B: Match the Pairs

# Source: https://example.com/sort-tutorial → A comment that records the URL where the reused code was found, so the original source can be traced.

# Author: J. Chen | Licence: MIT → A comment that names the person who wrote the reused code and the licence that allows you to use it.

Credit reused code by placing a comment above it naming the source, author and licence → # Source: Real Python, author: A. Lee, licence: CC BY 4.0 def bubble_sort(items):

Mark which lines are not your own so your work is clearly separated from borrowed code → # --- Start of code reused from library docs --- # --- End of reused code ---

# Found this online total = sum(prices) → The comment does not name the source, the author or the licence, so the original work is not properly credited.

def area(r): return 3.14 * r * r # Source: https://example.com/area (Ms Wu, CC0) → The credit comment is placed below the reused code instead of above it, so it is easy to miss which lines it refers to.

Section C: Definitions

# Source: — A comment placed above code you reused that names the source (such as a URL), the author and the licence, so the original work is credited and your own lines are clear.

Section D: Fill in the Blanks

# Source: https://example.com/sort

# Source: https://example.com/sort
# Author: Sam Lee
# Licence: MIT

# Reused code: start
total = sum(nums)
# Reused code: end

# Source: https://example.com/sort
# Author: Sam Lee
# Licence: MIT

Section E: Spot the Error

C — The licence line has no # at the start, so Python reads it as code and gives a syntax error. It should be # Licence: MIT.

D — The lines below were reused, so the comment must say they are not your own. It should be # Lines below are not my own.

A — A Source comment must name where the code came from, such as a URL. Claiming you wrote it does not credit the original. It should be # Source: stackoverflow.com/1.

A — // does not start a comment in Python, so this line causes an error. Python comments start with #, so it should be # Source: tutorials.com/loop.

C — This program is JavaScript, where # does not start a comment. The licence line must use //, like the other credit lines: // Licence: MIT.
