Quick Questions

Shade in the A or B circle for each question.

1. Which line makes the computer pick a secret number from 1 to 100?

A secret = random.randint(1, 100)

B secret = random(1, 100)

2. Which loop keeps a guessing game running until the player is right?

A while guess == secret:

B while guess != secret:

3. Where should the counter start before the loop begins?

A guesses = secret

B guesses = 0

4. Which line counts one more guess each turn of the loop?

A guesses = guesses + 1

B guesses == guesses + 1

5. The player guesses 40 and the secret is 25. Which hint is correct?

A Too high

B Too low

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1secret = random.randint(1, 20)		Aif guess > secret: print("Too high!")
2while guess != secret:		BThe counter is reset to 0 on every turn of the loop, so it can never count up. It should start at 0 before the loop and add 1 inside it.
3Count each turn by adding 1 to the guesses counter inside the loop		CA single = assigns a value to a variable. To compare two values you need the double equals == operator.
4Give a hint when the guess is bigger than the secret number		DKeeps repeating the indented lines until the player's guess is equal to the secret number
5if guess = secret: print("Correct!")		EPicks a random whole number from 1 to 20 and stores it as the secret number the player must guess
6secret = random.randint(1, 20) while guess != secret: guesses = 0		Fguesses = guesses + 1

Answer Key

Number guessing game with a loop, decisions and a counter

Section A: Quick Questions

A — secret = random.randint(1, 100)

B — while guess != secret:

B — guesses = 0

A — guesses = guesses + 1

A — Too high

Section B: Match the Pairs

secret = random.randint(1, 20) → Picks a random whole number from 1 to 20 and stores it as the secret number the player must guess

while guess != secret: → Keeps repeating the indented lines until the player's guess is equal to the secret number

Count each turn by adding 1 to the guesses counter inside the loop → guesses = guesses + 1

Give a hint when the guess is bigger than the secret number → if guess > secret: print("Too high!")

if guess = secret: print("Correct!") → A single = assigns a value to a variable. To compare two values you need the double equals == operator.

secret = random.randint(1, 20) while guess != secret: guesses = 0 → The counter is reset to 0 on every turn of the loop, so it can never count up. It should start at 0 before the loop and add 1 inside it.

Section C: Definitions

while guess != secret: — The loop at the heart of a guessing game. It keeps asking until the guess matches the random secret number. If/elif/else gives hints and a counter adds 1 each turn.

Section D: Fill in the Blanks

import random
secret = random.randint(1, 10)

secret = 7
guess = 0
while guess != secret:

while guess != secret:
    guess = int(input("Guess: "))
    count += 1

if guess < secret:
    print("Too low!")
elif guess > secret:

    print("Too high!")
else:
    print("Correct!")

Section E: Spot the Error

B — random is the module, not a function. The function that picks a whole number in a range is random.randint(1, 10).

A — Python uses the import keyword, not include. It should be import random, otherwise random.randint will not work.

A — == compares values, it does not store one. To start the counter at zero, use a single = : count = 0.

C — The if line is missing its colon at the end. It should be if guess > secret:

B — A single = assigns a value, so it can't be used as a loop test. The loop should keep going while the guess is not the secret: while guess != secret:
