Quick Questions
Shade in the A or B circle for each question.
1. Which list correctly names the five basic features of programming?
2. Which line of Python uses a VARIABLE?
3. Which code is a CONTROL STRUCTURE?
4. Which code is a DATA STRUCTURE?
5. Which statement describes SYNTAX in programming?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 1score = 0 | AA library: ready-made code that is brought into the program so you can reuse it | |
| 2import random | BThe variable total is used before it has been given a value, so Python cannot find it. | |
| 3A control structure decides which code runs or how many times it repeats | CA variable: a named place that stores a value the program can use and change | |
| 4A data structure stores a collection of related values under one name | Dfor i in range(5): print(i) | |
| 5if score > 50 print("Pass") | ESyntax error: the if line is missing its colon at the end. Syntax is the set of rules the code must follow. | |

Answer Key
The five basic features of programming
Section A: Quick Questions
Q1
B — Variables, control structures, data structures, syntax, libraries and classes
Q2
B — score = 10
Q3
A — for i in range(5):
Q4
A — marks = [88, 74, 95]
Q5
A — The rules for how code must be written so the computer can read it
Section B: Match the Pairs
Q1
score = 0 → A variable: a named place that stores a value the program can use and change
Q2
import random → A library: ready-made code that is brought into the program so you can reuse it
Q3
A control structure decides which code runs or how many times it repeats → for i in range(5):
print(i)
Q4
A data structure stores a collection of related values under one name → scores = [88, 74, 91]
Q5
if score > 50
print("Pass") → Syntax error: the if line is missing its colon at the end. Syntax is the set of rules the code must follow.
Q6
print(total)
total = 10 → The variable total is used before it has been given a value, so Python cannot find it.
Section C: Definitions
Q1
five features of programming — Every program is built from five features: variables, control structures, data structures, syntax, and libraries and classes.Section D: Fill in the Blanks
Q1
score = 10
print(score)Q2
lives = 3
while lives > 0:
lives = lives - 1Q3
names = ["Ava", "Liam", "Mia"]
print(names[0])Q4
age = 16
if age == 16:
print("Year 11")Q5
import random
print(random.randint(1, 6))Section E: Spot the Error
Q1
B — The variable is misspelled as scor, which was never created, so Python raises a NameError. It should be score = score + 10.
Q2
B — A control structure like if needs a colon at the end of its line (syntax). It should be if age >= 16:
Q3
C — The list has 3 items, so the valid indexes are 0, 1 and 2. Index 3 causes an IndexError. It should be colours[2].
Q4
B — With import random, the function must be called through the library name. It should be random.randint(1, 6).
Q5
C — This only changes a local variable, so the object never stores the name. It should be self.name = name.
