Python 3 Tkinter Tic Tac Toe Multiplayer Game Script Using Numpy Library GUI Desktop App Full Project For Beginners

Python 3 Tkinter Tic Tac Toe Multiplayer Game Script Using Numpy Library GUI Desktop App Full Project For Beginners

 

Welcome folks today in this blog post we will be building a multiplayer tic tac toe game using numpy library in tkinter using python. All the full source code of the application is given below.

 

 

Get Started

 

 

In order to get started you need to install the following library using the pip command as shown below

 

pip install numpy

 

After installing this library make an app.py file and copy paste the following code

 

app.py

 

from tkinter import *
import numpy as np

size_of_board = 800
symbol_size = (size_of_board / 3 - size_of_board / 8) / 2
symbol_thickness = 30
symbol_X_color = '#EE4035'
symbol_O_color = '#0492CF'
Green_color = '#7BC043'
