Lesson 25: Number Guessing Game

🎯 Project: Number Guessing Game

Let's build an interactive number guessing game! This project combines everything you've learned: random numbers, loops, conditionals, and user interaction. You'll create a game where the computer picks a random number and the player tries to guess it.

This project will help you practice using random.randint(), while loops, if/elif/else statements, and input handling.

Project Requirements

Your number guessing game should:

Generate a random number between 1 and 100
Allow the player to make guesses
Provide feedback (too high, too low, or correct)
Continue until the player guesses correctly
Track and display the number of attempts

Step-by-Step Guide

Here's how to build the game step by step:

game_steps.py
# Step 1: Import random module
import random

# Step 2: Generate random number
secret_number = random.randint(1, 100)

# Step 3: Initialize guess counter
attempts = 0

# Step 4: Create game loop
while True:
    # Get player's guess (for this exercise, use a provided value)
    guess = 50  # Replace with actual game logic
    attempts += 1
    
    # Compare guess with secret number
    if guess == secret_number:
        print(f"Congratulations! You guessed it in {attempts} attempts!")
        break
    elif guess < secret_number:
        print("Too low! Try again.")
    else:
        print("Too high! Try again.")

Complete Game Example

Here's a complete version of the game with all features:

complete_game.py
import random

# Welcome message
print("Welcome to the Number Guessing Game!")
print("I'm thinking of a number between 1 and 100.")

# Generate secret number
secret_number = random.randint(1, 100)
attempts = 0

# Game loop
while True:
    # For this exercise, simulate guesses (replace with actual input)
    # guess = int(input("Enter your guess: "))
    guess = random.randint(1, 100)  # Simulated guess
    attempts += 1
    
    print(f"Attempt {attempts}: You guessed {guess}")
    
    if guess == secret_number:
        print(f"🎉 Correct! You found it in {attempts} attempts!")
        break
    elif guess < secret_number:
        print("⬆️ Too low! Try a higher number.")
    else:
        print("⬇️ Too high! Try a lower number.")
    
    if attempts >= 10:
        print(f"Game over! The number was {secret_number}")
        break

Adding Features

Enhance your game with additional features:

enhanced_game.py
import random

# Difficulty levels
difficulty = "easy"  # easy, medium, hard

if difficulty == "easy":
    max_num = 50
    max_attempts = 10
elif difficulty == "medium":
    max_num = 100
    max_attempts = 7
else:
    max_num = 200
    max_attempts = 5

secret_number = random.randint(1, max_num)
print(f"Guess a number between 1 and {max_num}")
print(f"You have {max_attempts} attempts!")

attempts = 0
while attempts < max_attempts:
    attempts += 1
    remaining = max_attempts - attempts
    print(f"Attempt {attempts}/{max_attempts} ({} remaining)".format(remaining))
    
    # Game logic here
    break  # Placeholder

Tips and Best Practices

✅ Game Design Tips

• Start with a simple version, then add features

• Provide clear, helpful feedback to players

• Track attempts to make the game more engaging

• Consider adding difficulty levels or ranges

• Add a limit on attempts for challenge

💡 Testing Your Game

Test your game with different scenarios: correct guess on first try, many attempts, edge cases (1, 100). Make sure the feedback messages are clear and helpful!
