Answer Key

IDE function: prettyprint

Section A: Quick Questions

A — Shows code in a clear layout using colours and indentation

A — False

B — In a different colour from other text

A — Code is easier to read and errors are easier to spot

B — It indents the block

Section B: Match the Pairs

if x > 5: print(x) → Prettyprint shows the keyword if in a colour and indents the line inside the block, so the structure is easy to see.

# add the scores → Prettyprint shows a comment in its own colour, so it stands out from the code that runs.

Prettyprint uses indentation to show which lines belong inside a block such as a loop → for i in range(3): print(i)

Prettyprint is layout only: it changes how code looks on screen, not what the code does → print("Hi") # same output with or without colours

Prettyprint rewrites your code so that it runs faster. → Prettyprint only changes the display. It does not change the code or make it run faster.

Prettyprint finds and fixes the errors in your program. → Prettyprint does not fix errors. It only makes the code easier to read so the student can spot errors more easily.

Section C: Definitions

prettyprint — An IDE feature that shows code in a clear layout, using colours for keywords and indentation for blocks, so it is easy to read. It changes only the display, not the code.

Section D: Fill in the Blanks

# prettyprint colours keywords in the editor

if score > 50:
    print("Pass")

FOR i ← 1 TO 3
    OUTPUT i
NEXT i

# Comments get their own colour
print("Hi")

# Prettyprint changes layout, not the code

Section E: Spot the Error

A — The comment is missing its # symbol, so it is treated as code and will not be shown in the comment colour. It should be '# Prettyprint colours comments'.

B — The closing quote is missing, so prettyprint would colour the rest of the line as one string. It should be print("Hello " + name).

D — The function name print is misspelled. Prettyprint colours the real function name, so the misspelling stands out as uncoloured. It should be print("Done").

C — There is a stray closing bracket at the end of the line. A prettyprinted layout makes this easier to spot. It should be ' total = total + n'.

B — Keywords are case-sensitive, so 'If' would not be shown in the keyword colour. The keyword should be lowercase: if age >= 16:
