Hello Guys,
Most of us have overhear about the famous pong game and many of us love playing it. Today lets we grasp how to code this classic game using the python programming language!
Before start coding we first need to install the turtle module. The turtle module is a library of Python Language that allows the user to make pictures and shapes by providing them with a virtual canvas.

Step#1

If have not installed the library, Install the library using pip in command prompt or Shell
C:\Users\Admin>pip install turtle

Step#2

First we need to open source where we can write code VScode,Pycharm,Shell etc. Pycharm supports extra features for python I'll prefere you to use Pycharm for python.

We need to import turtle Library which we have installed in our PC in python path

 import turtle as t
 playerAscore=0
 playerBscore=0

Step#3:

#create a window and declare a variable called window and call the screen()

 window=t.Screen()
 window.title("The Pong Game")
 window.bgcolor("green")
 window.setup(width=800,height=600)
 window.tracer(0)

Step#4

We're starting to create the left paddle.

 leftpaddle=t.Turtle()
 leftpaddle.speed(0)
 leftpaddle.shape("square")
 leftpaddle.color("white")
 leftpaddle.shapesize(stretch_wid=5,stretch_len=1)
 leftpaddle.penup()
 leftpaddle.goto(-350,0)

Step#5

Now we're creating the right paddle.

 rightpaddle=t.Turtle()
 rightpaddle.speed(0)
 rightpaddle.shape("square")
 rightpaddle.color("white")
 rightpaddle.shapesize(stretch_wid=5,stretch_len=1)
 rightpaddle.penup()
 rightpaddle.goto(-350,0)

Step#6

Code for creating the ball

 ball=t.Turtle()
 ball.speed(0)
 ball.shape("circle")
 ball.color("red")
 ball.penup()
 ball.goto(5,5)
 ballxdirection=0.2
 ballydirection=0.2

Step#7

Code for creating pen for scorecard update.

 pen=t.Turtle()
 pen.speed(0)
 pen.color("Blue")
 pen.penup()
 pen.hideturtle()
 pen.goto(0,260)
 pen.write("score",align="center",font=('Arial',24,'normal'))

Step #8

Code for moving left and right paddle.

def leftpaddleup():
    y=leftpaddle.ycor()
    y=y+90
    leftpaddle.sety(y)

def leftpaddledown():
     y=leftpaddle.ycor()
     y=y+90
     leftpaddle.sety(y)

#moving the rightpaddle
def rightpaddleup():
    y=rightpaddle.ycor()
    y=y+90
    rightpaddle.sety(y)

def rightpaddledown():
    y=rightpaddle.ycor()
    y=y+90
    rightpaddle.sety(y)

Step#9

Here we are working for output, Assigning keys for output.

window.listen()
window.onkeypress(leftpaddleup,'w')
window.onkeypress(leftpaddledown,'s')
window.onkeypress(rightpaddleup,'Up')
window.onkeypress(rightpaddledown,'Down')

while True:
    window.update()
    #moving the ball
    ball.setx(ball.xcor()+ballxdirection)
    ball.sety(ball.ycor()+ballxdirection)

    #border set up
    if ball.ycor()>290:
        ball.sety(290)
        ballydirection=ballydirection*-1
    if ball.ycor()<-290:
        ball.sety(-290)
        ballydirection=ballydirection*-1
     
    if ball.xcor() > 390:
        ball.goto(0,0)
        ball_dx = ball_dx * -1
        player_a_score = player_a_score + 1
        pen.clear()
        pen.write("Player A: {}                    Player B: {} ".format(player_a_score,player_b_score),align="center",font=('Monaco',24,"normal"))
        os.system("afplay wallhit.wav&")



    if(ball.xcor()) < -390: # Left width paddle Border
        ball.goto(0,0)
        ball_dx = ball_dx * -1
        player_b_score = player_b_score + 1
        pen.clear()
        pen.write("Player A: {}                    Player B: {} ".format(player_a_score,player_b_score),align="center",font=('Monaco',24,"normal"))
        os.system("afplay wallhit.wav&")

Step#10

Here we're working for collision provision, It might possible that paddles collide so code for collision of paddles.

    if(ball.xcor() > 340) and (ball.xcor() < 350) and (ball.ycor() < paddle_right.ycor() + 40 and ball.ycor() > paddle_right.ycor() - 40):
        ball.setx(340)
        ball_dx = ball_dx * -1
        os.system("afplay paddle.wav&")

    if(ball.xcor() < -340) and (ball.xcor() > -350) and (ball.ycor() < paddle_left.ycor() + 40 and ball.ycor() > paddle_left.ycor() - 40):
        ball.setx(-340)
        ball_dx = ball_dx * -1
        os.system("afplay paddle.wav&")
