Guess the Number Project

In this project, we will build a simple game where the user has to guess a randomly generated number.

The goal is to bring together everything you have learned so far: variables, conditionals, loops, and functions.

What we are building

The program will:

generate a random number
ask the user to guess the number
tell the user if the guess is too high or too low
repeat until the user guesses correctly

At the end, we will also build a simple graphical interface using Tkinter.

Step 1: Generate a random number

First, we need to generate a random number.

import random

number = random.randint(1, 100)

This creates a random number between 1 and 100.

Step 2: Get user input

Now we ask the user for a guess:

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

We convert the input to an integer using int().

Step 3: Compare the guess

We use conditionals to compare the guess with the number:

if guess < number:
    print("Too low")
elif guess > number:
    print("Too high")
else:
    print("Correct")

Step 4: Repeat using a loop

We want the user to keep guessing until they find the correct number.

while guess != number:
    guess = int(input("Enter your guess: "))

    if guess < number:
        print("Too low")
    elif guess > number:
        print("Too high")
print("Correct")

Step 5: Organizing with functions

We can improve the structure by using functions:

import random


def get_random_number():
    return random.randint(1, 100)


def check_guess(guess, number):
    if guess < number:
        return "Too low"
    elif guess > number:
        return "Too high"
    else:
        return "Correct"


def play_game():
    number = get_random_number()
    guess = None

    while guess != number:
        guess = int(input("Enter your guess: "))
        result = check_guess(guess, number)
        print(result)


play_game()

Step 6: Simple UI with Tkinter

Now we will build a simple graphical interface.

import random
import tkinter as tk

number = random.randint(1, 100)


def check():
    guess = int(entry.get())

    if guess < number:
        label.config(text="Too low")
    elif guess > number:
        label.config(text="Too high")
    else:
        label.config(text="Correct")


root = tk.Tk()
root.title("Guess the Number")

entry = tk.Entry(root)
entry.pack()

button = tk.Button(root, text="Check", command=check)
button.pack()

label = tk.Label(root, text="Enter a number")
label.pack()

root.mainloop()

This creates a basic window where the user can input a number and receive feedback.

The end!

Congrats for building the final project. You have now mastered the basics of Python and succesfully understood the basic concepts in programming :)

tip

You can improve your project further by:

adding a limited number of attempts
displaying the number of tries
adding a restart button in the UI

You can always check the documentation of tkinter for more details on how to use it!
