您的问题有点含糊。这是一个可能会帮助您的乒乓程序：

import turtle
 
wn = turtle.Screen()
wn.title("Ping pong")
wn.bgcolor("blue")
wn.setup(width=900, height=600)
wn.tracer(0)  
 
 
class PaddleFirst():
    def __init__(self):
        self.pen = turtle.Turtle()
        self.pen.penup()
        self.pen.speed(0)
        self.pen.shape("square")
        self.pen.shapesize(stretch_wid=5, stretch_len=1)
        self.pen.penup()
        self.pen.goto(-350, 0)
 
    def up(self):
        y = self.pen.ycor()
        y += 20
        self.pen.sety(y)
 
    def down(self):
        y = self.pen.ycor()
        y -= 20
        self.pen.sety(y)
 
 
class PaddleSecond():
    def __init__(self):
        self.pen = turtle.Turtle()
        self.pen.penup()
        self.pen.speed(0)
        self.pen.shape("square")
        self.pen.shapesize(stretch_wid=5, stretch_len=1)
        self.pen.penup()
        self.pen.goto(350, 0)
 
    def up(self):
        y = self.pen.ycor()
        y += 20
        self.pen.sety(y)
 
    def down(self):
        y = self.pen.ycor()

    def letsgo(self):
        self.pen.setx(self.pen.xcor() + self.pen.dx)
        self.pen.sety(self.pen.ycor() + self.pen.dy)
 
    def move(self):
        if self.pen.ycor() > 290:
            self.pen.sety(290)
            self.pen.dy *= -1
 
        if self.pen.ycor() < -290:
            self.pen.sety(-290)
            self.pen.dy *= -1

paddle1 = PaddleFirst()
print(paddle1)
