Quick Questions
Shade in the A or B circle for each question.
1. Which line must come at the top of your program before you can use random.randint()?
2. Which code gives a random whole number from 1 to 6, like rolling a dice?
3. True or false: random.randint(1, 10) can return the number 10.
4. Which line correctly stores a random number in a variable?
5. Which code picks a random item from the list pets = ["cat", "dog", "fish"]?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.

Answer Key
Random numbers with import random
Section A: Quick Questions
Q1
B — import random
Q2
A — random.randint(1, 6)
Q3
B — True
Q4
A — num = random.randint(1, 100)
Q5
A — random.choice(pets)
Section B: Match the Pairs
Q1
import random → Gives your program the random module so you can use random.randint() and random.choice()
Q2
random.randint(1, 6) → Gives a random whole number from 1 to 6, including both 1 and 6
Q3
Roll a dice and save the random whole number from 1 to 6 in a variable → roll = random.randint(1, 6)
Q4
Pick a random item from a list of snacks → random.choice(snacks)
Q5
num = random.randint(1, 10)
(no import random line at the top) → The import random line is missing, so Python does not know what random is and shows a NameError. Add import random at the top.
Q6
import random
num = randint(1, 10) → randint is called without random. in front. It should be random.randint(1, 10).
Section C: Definitions
Q1
import random — Gives your program the random module. Then random.randint(1, 6) gives a random whole number from 1 to 6, and random.choice(my_list) picks a random item from a list.Section D: Fill in the Blanks
Q1
import randomQ2
import randomQ3
roll = random.randint(1, 6)Q4
roll = random.randint(1, 6)Q5
pick = random.choice(colours)Section E: Spot the Error
Q1
D — A single = assigns a value. To compare dice with 6 you need ==, so the line should be: if dice == 6:
Q2
A — The module name is spelled wrong. It must be random, so the line should be: import random
Q3
B — With just import random, randint must be called with the module name in front. It should be: n = random.randint(1, 100)
Q4
C — The function that picks a random item from a list is random.choice(), not random.choose(). It should be: pick = random.choice(pets)
Q5
C — Functions are called with round brackets (), not square brackets []. It should be: c = random.choice(colours)
