Ping Pong Game In Python With Turtle

 

This is a super cool Ping Pong game development project in python using the Turtle library. Its a good exercise for python developers and can increase the logic buildings skills for beginner developers.

The source code for the project is following : 

import turtle as t
import os
# Score variables
player_a_score = 0
player_b_score = 0
win = t.Screen()    # creating a window
win.title("Ping-Pong Game") # Giving name to the game.
win.bgcolor('black')    # providing color to the HomeScreen
win.setup(width=800,height=600) # Size of the game panel 
win.tracer(0)   # which speed up's the game.
# Creating left paddle for the game
paddle_left = t.Turtle()
paddle_left.speed(0)
paddle_left.shape('square')
paddle_left.color('red')
paddle_left.shapesize(stretch_wid=5,stretch_len=1)
paddle_left.penup()
paddle_left.goto(-350,0)
# Creating a right paddle for the game
paddle_right = t.Turtle()
paddle_right.speed(0)
paddle_right.shape('square')
paddle_right.shapesize(stretch_wid=5,stretch_len=1)
paddle_right.color('red')
paddle_right.penup()
paddle_right.goto(350,0)
# Creating a pong ball for the game
ball = t.Turtle()
ball.speed(0)
ball.shape('circle')
ball.color('yellow')
ball.penup()
ball.goto(0,0)
ball_dx = 1.5   # Setting up the pixels for the ball movement.
