Build a Number Guessing Game in Python

If you’re just starting out with Python and want a fun, quick project to test your skills — this one’s for you.

In this tutorial, we’ll guide you step-by-step to create a Number Guessing Game using Python. It’s simple, interactive, and helps you practice key concepts like:

• Variables
• Loops
• Conditional statements
• Random number generation
• User input

Let’s get coding! 💻

🧠 What Does the Game Do?

• The computer picks a random number between 1 and 100.
• You try to guess the number.
• It tells you if your guess is too high or too low.
• It keeps going until you guess correctly.
• At the end, it shows how many tries you took.

🧰 Tools You Need

You can run this code on:

• ✅ Replit (browser-based)
• ✅ Google Colab
• ✅ Python installed locally (with VS Code or IDLE)

🧾 Step-by-Step Python Code

✅ Full Code:

pythonCopyEditimport random

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

# Generate a random number
secret_number = random.randint(1, 100)
guesses = 0

while True:
    try:
        guess = int(input("Enter your guess: "))
        guesses += 1

        if guess < secret_number:
            print("Too low! Try again.")
        elif guess > secret_number:
            print("Too high! Try again.")
        else:
            print(f"Congratulations! You guessed it in {guesses} tries.")
            break
    except ValueError:
        print("Please enter a valid number.")

🔍 Code Explained Line by Line

• import random
  This lets us generate random numbers.
• random.randint(1, 100)
  Picks a random number between 1 and 100 (inclusive).
• while True:
  This keeps the game running until the user guesses correctly.
• int(input(...))
  Gets the user’s input and converts it to an integer.
• if, elif, else
  Controls the game logic — tells user if the guess is too high, low, or correct.
• break
  Exits the loop when the correct number is guessed.
• try/except
  Catches input errors so the program doesn’t crash if the user types a letter.

🛠️ Ways to Customize the Game

• 🔁 Add difficulty levels (Easy: 1–50, Hard: 1–200)
• ⏱️ Add a timer
• 📊 Track high scores
• 🔊 Add sound using the playsound module
• 🎨 Add graphics with tkinter (advanced)

🎯 Final Thoughts

This game is a great introduction to real-world Python programming. It uses the core concepts of logic, user input, and randomness — all in less than 25 lines of code!

Practice tweaking the code, adding features, and challenging yourself to make it even better.
