Question:

# Paddle A
paddle_a = turtle.Turtle()
paddle_a.speed(0)
paddle_a.shape("square")
paddle_a.color("white")
paddle_a.shapesize(stretch_wid=6, stretch_len=1)
paddle_a.penup()
paddle_a.goto(-350, 0)

# Paddle B
paddle_b = turtle.Turtle()
paddle_b.speed(0)
paddle_b.shape("square")
paddle_b.color("white")
paddle_b.shapesize(stretch_wid=6, stretch_len=1)
paddle_b.penup()
paddle_b.goto(350, 0)

# Ball
ball = turtle.Turtle()
ball.speed(40)
ball.shape("square")
ball.color("white")
ball.penup()
ball.goto(0, 0)
ball.dx = 0.2  # Ball's x-axis speed
ball.dy = 0.2  # Ball's y-axis speed

# Function to move Paddle A up
def paddle_a_up():
    y = paddle_a.ycor()
    if y < 250:
        y += 20
    paddle_a.sety(y)

# Function to move Paddle A down
def paddle_a_down():
    y = paddle_a.ycor()
    if y > -240:
        y -= 20
    paddle_a.sety(y)

# Function to move Paddle B up
def paddle_b_up():
    y = paddle_b.ycor()
    if y < 250:
        y += 20
    paddle_b.sety(y)

# Function to move Paddle B down
def paddle_b_down():
    y = paddle_b.ycor()
    if y > -240:
        y -= 20
    paddle_b.sety(y)

# Keyboard bindings
wn.listen()
wn.onkeypress(paddle_a_up, "w")
wn.onkeypress(paddle_a_down, "s")
wn.onkeypress(paddle_b_up, "Up")
wn.onkeypress(paddle_b_down, "Down")

# Main game loop
while True:
    wn.update()

    # Move the ball
    ball.setx(ball.xcor() + ball.dx)
    ball.sety(ball.ycor() + ball.dy)

    # Check collision with top/bottom walls
    if ball.ycor() > 290 or ball.ycor() < -290:
        ball.dy *= -1

    # Check collision with paddles
    if (ball.dx > 0) and (350 > ball.xcor() > 340) and (paddle_b.ycor() + 50 > ball.ycor() > paddle_b.ycor() - 50):
        ball.color("green")
        ball.setx(340)
        ball.dx *= -1

    elif (ball.dx < 0) and (-350 < ball.xcor() < -340) and (paddle_a.ycor() + 50 > ball.ycor() > paddle_a.ycor() - 50):
        ball.color("blue")
        ball.setx(-340)
        ball.dx *= -1

@GulamRasool3, I looked at your repl here and saw that the code you posted is in a file with no extension. By default, Replit runs main.py so if you want the ping pong code to run, you should add the code to the main.py file.

Instead of transferring the code to a file main.py , you can write to the file main.py this line of code:

from your_file_name import *

That’d work, except python expects the file to have a .py extension when importing, so it would not be able to find the file.
