Number Guessing Game Using Python Tkinter Module

Last Updated : 24 Apr, 2025

Number Guessing Game using the Python Tkinter module is a simple game that involves guessing a randomly generated number. The game is developed using the Tkinter module, which provides a graphical user interface for the game. The game has a start button that starts the game and a text entry field where the user can enter their guess. The game also has a status label that displays the game status, such as "Too High", "Too Low", or "Correct". If the user enters the correct number, a message is displayed indicating that they have won the game. If the user fails to guess the number, the game restarts automatically, generating a new number to be guessed. The game continues until the user wins. The game is designed to be simple and user-friendly, making it an ideal project for beginners to learn the basics of the Python Tkinter module and game development.

Rules of Games

You are given only 10 attempts to guess the number.
The number generated randomly with each attempt your score will going to reduce.

The language used

Python

Steps to create a project

Step 1.

Install and Import all required modules which are PIL (Pillow), and Tkinter. Tkinter provides a graphical user interface where we are going to develop a UI for users.

pip install tk
pip install Pillow

Python

from tkinter import *
from PIL import ImageTk,Image
import random
import tkinter.messagebox as tmsg

Step 2.

Create a function to generate a number

Python3

def generate():
    global comp
    comp=random.randint(1, 101)

Here We are using the randint function of Python to generate the random number between 1 and 100.

Step 3.

Defining function which will have all configuration of UI screen - title, the geometry of screen, min and max size, etc.

Python

def basic():
    # setup the window size, title, logo
    app.title("Number Guessing game")
    app.geometry("500x500")
    app.minsize(500, 500)
    app.maxsize(500, 500)
    photo = PhotoImage(file="guess.png")
    app.iconphoto(False, photo)
    heading = Label(text='Number Guessing game', font="Helvicta 18 bold",
                    bg='black', fg='tomato', padx=170).pack()
    with open('score.txt', 'r') as f:
        hg = f.read()
    sc = Label(app, text=f'Previous score: {hg}', font='lucida 8 bold ').pack(
        anchor=E, padx=25, pady=5)

    # footer
    footer = Label(text='Developed by Siddharth Dyamgond', font="Helvicta 8 bold",
                   bg='black', fg='tomato', padx=153).pack(side=BOTTOM)

    # Setup Menu
    mymenu = Menu(app)
    filee = Menu(mymenu, tearoff=0)
    mymenu.add_cascade(label='Start', menu=filee)
    mymenu.add_cascade(label='Restart', command=restart)
    mymenu.add_command(label='About', command=call1)
    mymenu.add_command(label='Quit', command=quit)
    app.config(menu=mymenu)
    generate()

The geometry () function is used to set the size of the Main Window

Step 4.

Initializing the screen by calling the constructor of Tkinter TK() and taking user input from the user

Python

app = Tk()
basic()
count = 0
comp = random.randint(1, 101)  # generating random values between 1 to 100
userv = StringVar()  # variable to getting input in string format

# creating input field
user = Entry(app, textvariable=userv, justify=CENTER, relief=FLAT,
             borderwidth=2, font='Helvicta 18 bold').pack(pady=10)

# submit button
i = Image.open('bt.jpg')
resized_image = i.resize((150, 50), Image.ANTIALIAS)
new_image = ImageTk.PhotoImage(resized_image)
submit = Button(app, image=new_image, command=result,
                font='Helvicta 18 bold', relief=FLAT).pack(pady=10)
show = Label(app, text='', font='Helvicta 12 bold')
show.pack(pady=10)

The Button Function is used to submit the guessed value by the user.

Step 5.

Declaring result function which will validate the user input and display message according to user input.

Python

def result():
    global count
    number=userv.get()
    if number=='':
        tmsg.showerror('Error',"Please enter a value")
    else:
        n=int(number)
        count+=1
        if count==10:
            a=tmsg.showinfo('Game over','You loose the Game!')
        elif comp==n:
            score=11-count
            a=tmsg.showinfo('Win',f'You guess right number!\nYour score {score}')
            show.config(text='Winn!',fg='green')
            with open('score.txt','w') as f:
                f.write(str(score))
            generate()
            tmsg.showinfo('Next number',f'click ok to Guess another number')
        elif comp>n:
            show.config(text='Select greater number',fg='red')
        else:
            show.config(text='Select smaller number',fg='red')

This Function is doing logical calculations and shows the dialog box according to conditions.

Here Open Function is used to write a score of the user if he guessed correctly.

Step 6.

Creating a reset function to restart our game

Python3

def restart():
    tmsg.showerror('Reset',"Game reset!")
    generate()

This function shows a dialog box to the user of a particular message. Then restart it again.

Step 7.

Finally initialized game using the main loop () function.

Python

app.mainloop()
