Answer Key

IDE function: code editor

Section A: Quick Questions

A — The code editor

B — They help you find and refer to a line, for example when an error message names line 12

B — Shows keywords in different colours

A — A code editor in an IDE

A — Syntax highlighting in the code editor

Section B: Match the Pairs

code editor → The part of an IDE where the programmer types and edits source code

syntax highlighting → Colour-coding keywords, strings and numbers in the code editor so they are easier to spot

A code editor shows line numbers down the side so you can find the line an error message mentions → 1 name = input("Name: ") 2 print(name)

A code editor uses syntax highlighting, so keywords such as print and if appear in a different colour from the rest of the code → if age >= 16: # 'if' shown in colour

A code editor is the part of an IDE that translates source code into machine code. → This describes a translator (compiler or interpreter), not the code editor. The code editor is where you type and edit the source code.

A plain text editor like Notepad gives line numbers and colour-coded keywords just like a code editor in an IDE. → A plain text editor does not normally give line numbers or syntax highlighting. These features are what make a code editor different.

Section C: Definitions

code editor — The part of an IDE where you type and edit source code. It shows line numbers and syntax highlighting (colour-coded keywords), which a plain text editor does not.

Section D: Fill in the Blanks

# The code editor colours keywords
print("Score:", 10)
# print is shown in a keyword colour

for i in range(3):
    print(i)

score = 60
if score > 50:
    print("Pass")

# This comment is shown in a new colour

def greet(name):
    print("Hi", name)

Section E: Spot the Error

D — An if statement must end with a colon. Without it the code has a syntax error. It should be: if has_line_numbers:

C — The closing bracket is missing from the print call. A code editor can help you spot this, but the fix is: print("Blue:", word)

A — Python uses the keyword def, not define. A code editor with syntax highlighting would not colour define as a keyword, which is a clue that it is wrong.

D — The variable being assigned to must be on the left of the = sign. It should be: count = count + 1

A — The string is missing its closing quote. A code editor with syntax highlighting would colour the rest of the line as text, showing the mistake. It should end with ".
