Exercise: The Guessing Game¶

Create a game where the computer picks a random number and the player tries to guess it!

Your Task¶

Build a guessing game with these features:

Computer picks a random number between 1 and 100
Player gets 10 attempts to guess
After each wrong guess, tell them if the secret number is higher or lower
If they guess correctly, they win!
If they run out of guesses, they lose

Example Game Play¶

Welcome to the Number Guessing Game!
I'm thinking of a number between 1 and 100.
You have 10 guesses.

Guess 1: 50
Too low! The secret number is higher.

Guess 2: 75
Too high! The secret number is lower.

Guess 3: 62
Too low! The secret number is higher.

Guess 4: 68
Congratulations! You got it in 4 guesses!

Getting Started¶

# Import random number generator
from random import randint

# Generate secret number
secret_number = randint(1, 100)

# Game loop
for guess_count in range(10):
    # Get player's guess
    guess = int(input(f"Guess {guess_count}: "))

Key Functions You'll Need¶

Random number:

This is something new, but here we're import-ing a new helpful function, randint which returns a random number from within a range.

from random import randint
secret = randint(1, 100)  # Random number from 1 to 100

Getting user input as a number: You'll want to covnert the guess into an integer to match the secret.

guess = int(input("Enter your guess: "))

Loop for 10 attempts: The user will have 10 attemps

for attempt in range(10):
    # This runs 10 times with attempt = 1, 2, 3... 10

Tips¶

Use break to exit the loop when they guess correctly
The else in if/elif/else handles the "too high" case
Consider adding a print statement to "whisper" the secret number to you as you're working out the kinks in your game.

Bonus Challenges¶

Tell them how many guesses they have left after each attempt
Ask the user for a difficulty level (easy: 1-50, medium: 1-100, hard: 1-200)
Add a play again feature using a while loop and keep track of their lowest number of guesses.

In [7]:

# Import random number generator
from random import randint

# Choose Difficulty
while True:
    difficulty = input("What is your difficulty level (easy, medium, hard)? ")
    if difficulty == "easy":
        max_randint = 50
        break
    elif difficulty == "medium":
        max_randint = 100
        break
    elif difficulty == "hard":
        max_randint = 200
        break
    else:
        print(f"Invalid difficulty '{difficulty}'")

max_guesses = 10
best_score = max_guesses + 1

while True:

    # Generate secret number
    secret_number = randint(1, max_randint)

    # Game loop
    for guess_count in range(1, max_guesses + 1):
        guess = int(input(f"Guess {guess_count}: "))

        # Hints
        if guess < secret_number:
            print("WRONG! The secret number is higher.")
        elif guess > secret_number:
            print("WRONG! The secret number is lower.")

        # Win Condition
        else:
            print(f"CORRECT! The scret number was {guess}.")
            print(f"Score: {guess_count}")
            if guess_count < best_score:
                best_score = guess_count
                print(f"New Best Score: {best_score}")
            break

        # Guesses Remaining
        guesses_left = max_guesses - guess_count
        print(f"You have {guesses_left} guesses remaining")

    continue_game = input("Would you like to play again (yes, no)? ")
    if continue_game == "no":
        print(f"Your best score was: {best_score}")
        break

What is your difficulty level (easy, medium, hard)? medium
WHISPER: 'the secret number is 17'
Guess 1: 50
WRONG! The secret number is lower.
You have 9 guesses remaining
Guess 2: 25
WRONG! The secret number is lower.
You have 8 guesses remaining
Guess 3: 9
WRONG! The secret number is higher.
You have 7 guesses remaining
Guess 4: 17
CORRECT! The scret number was {guess}.
Score: 4
New Best Score: 4
Would you like to play again (yes, no)? yes
WHISPER: 'the secret number is 68'
Guess 1: 11
WRONG! The secret number is higher.
You have 9 guesses remaining
Guess 2: 15
WRONG! The secret number is higher.
You have 8 guesses remaining
Guess 3: 38
WRONG! The secret number is higher.
You have 7 guesses remaining
Guess 4: 49
WRONG! The secret number is higher.
You have 6 guesses remaining
Guess 5: 68
CORRECT! The scret number was {guess}.
Score: 5
Would you like to play again (yes, no)? no
Your best score was: 4
