Turtle Racer如何在python中添加第一第二和第三菜单

Question

因此，我有一个11年级的项目，需要在此代码中添加一个部分，以便在类似于此的菜单中列出越过终点线的前3只海龟，但是我需要它说第一名，第二名，第三名，然后将相应的海龟移到那里。麻烦的是，我制作的新曲目（项目告诉我），但是在第一个乌龟越过后，乌龟就不会越过终点线，而且我不确定如何添加新菜单作为代码最初给予没有意义。

我当前拥有的代码如下；

# Creating the window
screen = turtle.Screen()
screen.setup(1225, 1000)

pil_img = Image.open("eightLane.gif")  # Use PIL to open .jpg image.
tk_img = ImageTk.PhotoImage(pil_img)  # Convert it into something tkinter can use.
canvas = turtle.getcanvas()  # Get the tkinter Canvas of this TurtleScreen.
# Create a Canvas image object holding the tkinter image.
img_obj_id = canvas.create_image(0, 0, image=tk_img, anchor='center')

#in future adjust position

    ('red', (0, 90)), #creates each turtle and where it goes

for index, (color, position) in enumerate(LINEUP):

    racer = Turtle('turtle', visible=False) #pen settings for placing the turtles initially
    racer.setheading(180 + index * 10)
    racer.speed('fastest')
    racer.color(color) 
    racer.penup()
    racer.setposition(position)
    racer.showturtle() #shows the turtle now that it is in position

    racers.append(racer)



DELTA = 0.4  # angle at which they move

def radii(index):  # calculate concentric ellipse radii
    return 265 + index * 44, 90 + index * 36

def race(): #how often it moves a turtle
    """
    every 1/1000th of a second, pick a random 
    racer and move it forward a bit
    """

    index = randrange(len(racers)) 
    racer = racers[index]

    # get angle from x, y; increase angle; compute new x, y
    theta = atan2(racer.ycor(), racer.xcor()) + DELTA

    a, b = radii(index)

    x = a * cos(theta) #fancy maths
    y = b * sin(theta)

    racer.setheading(racer.towards(x, y)) #tells the racer where to face
    racer.setposition(x, y)  # moves the racer to the position 

    # check if a racer has crossed the finish line
    if pi/2 < theta < pi/2 + DELTA/2: #if the racer has crossed the line run next line else skip
        pass  #someone one
    else:
        screen.ontimer(race, 100) #keeps the loop going

race()
screen.mainloop()
