Answer Key
Syntax Errors and Debugging
Section A: Quick Questions
Q1
A — Stops and shows an error message
Q2
A — The console panel
Q3
A — The line number of the problem
Q4
B — True
Q5
B — Click Run to test the fix
Section B: Match the Pairs
Q1
syntax error → An error caused by a typo, missing quote, or wrong bracket that stops Python running
Q2
print("Hello, world!) → Syntax error — the closing quote is missing from the string
Q3
Debugging means finding and fixing the error in your code → # Find the bug
# Fix it
# Click Run to test
Q4
The error message shows the line number where Python got confused → # SyntaxError on line 3
# Check line 3 for a typo
Q5
print(Hello, world!) → Syntax error — string must be wrapped in quote marks
Q6
# Python keeps running after a syntax error → Wrong — Python stops immediately and shows an error message
Section C: Definitions
Q1
syntax error — An error that occurs when Python cannot understand your code due to a typo, missing quote, or wrong bracket; Python stops and shows a message with the line numberSection D: Fill in the Blanks

Q1
A — Python stops immediately when it finds a syntax error — it does not keep running. Line 0 is wrong.
Q2
B — Python does not ignore syntax errors — it stops and shows an error message. Line 1 is wrong.
Q3
C — Syntax errors can happen on any line, not just the last one. Line 2 is wrong.
Q4
A — Every programmer makes syntax errors — they are a normal part of coding at any skill level. Line 0 is wrong.
Q5
B — After fixing a bug you should click Run to re-test, not Reset. Reset only restores starter code. Line 1 is wrong.
