Number Guessing Game with AI

View on GitHub

Abstract

Challenge yourself against an AI in a number guessing game! The AI uses binary search to guess your number, then you try to guess the AI’s number. Compare rounds to see who wins and learn about efficient algorithms in action.

Prerequisites

  • Python 3.6 or above
  • Text Editor or IDE
  • Basic understanding of Python syntax
  • Understanding of loops and input/output
  • Familiarity with binary search (helpful)

Getting Started

Create a new project

  1. Create a new project folder and name it numberGuessingWithAInumberGuessingWithAI.
  2. Create a new file and name it numberguessingwithai.pynumberguessingwithai.py.
  3. Open the project folder in your favorite text editor or IDE.
  4. Copy the code below and paste it into your numberguessingwithai.pynumberguessingwithai.py file.

Write the code

  1. Add the following code to your numberguessingwithai.pynumberguessingwithai.py file.

  1. Save the file.
  2. Run the following command to run the application.
command
C:\Users\username\Documents\numberGuessingWithAI> python numberguessingwithai.py
Think of a number between 0 and 100!
Is your number 50? (h/l/y): h
Is your number 75? (h/l/y): l
Is your number 62? (h/l/y): l
Is your number 56? (h/l/y): y
I guessed your number in 4 rounds!
Now guess my number between 0 and 100:
50
Too low! Try again: 75
Too high! Try again: 62
Correct! You guessed my number in 3 rounds!
You win this round!

Explanation

  1. The import randomimport random statement imports the random module for generating random numbers.
  2. The AI uses binary search algorithm to efficiently guess your number.
  3. The lowlow and highhigh variables maintain the search range for the AI.
  4. The AI starts by guessing the middle value (50) and adjusts based on your response.
  5. Your responses (‘h’ for higher, ‘l’ for lower, ‘y’ for yes) guide the AI’s search.
  6. The random.randint(0, 100)random.randint(0, 100) generates a random number for you to guess.
  7. The program tracks rounds taken by both AI and human player.
  8. Winner determination compares the number of rounds each player needed.
  9. The binary search algorithm guarantees the AI will find any number in at most 7 rounds.
  10. The game demonstrates the efficiency of algorithmic problem-solving vs. human intuition.

Next Steps

Congratulations! You have successfully created a Number Guessing Game with AI in Python. Experiment with the code and see if you can modify the application. Here are a few suggestions:

  • Add difficulty levels (change range from 0-100 to larger ranges)
  • Track high scores and statistics across multiple games
  • Add GUI with Tkinter for better user experience
  • Let AI learn from previous games to improve performance
  • Implement different AI strategies (random, pattern-based)
  • Add multiplayer support for multiple human players
  • Create tournament mode with best-of-series gameplay
  • Add sound effects and visual feedback
  • Implement hints system for human player

Conclusion

In this project, you learned how to create a Number Guessing Game with AI in Python. You also learned about binary search algorithms, human vs. computer problem-solving, and competitive programming concepts. You can find the source code on GitHub
