我似乎无法让我的两只眼睛为 Turtle 工作

Question

So what am I missing here? I simply need to have 2 eyes that are filled in with the color red. I'm not sure what is missing for the "def eye", but I'm sure that's where I have made a mistake.

import turtle

t = turtle.Turtle()

def DCircle(x,y,radius,color):
    t.penup()
    t.setposition(x,y)
    t.pendown()
    t.fillcolor(color)
    t.begin_fill()
    t.color(color)
    t.circle(radius)
    t.end_fill()

def eye(color, radius):
    t.penup()
    t.setposition(-50,40)
    t.pendown()
    t.fillcolor(color)
    t.color(red)
    t.begin_fill()
    t.circle(radius)
    t.end_fill()

def Mickey():
    r = 50
    DCircle(0,0,2*r,'blue')
    DCircle(-135,115,r,'red')
    DCircle(135,115,r,'red')

def Main():
    Mickey()
    turtle.done()
    turtle.bye()
    turtle.getscreen()._root.mainloop()

Main()

I think you are trying to do this:

import turtle

t = turtle.Turtle()

def DCircle(x,y,color,radius):
    t.penup()
    t.setposition(x,y)
    t.pendown()
    t.fillcolor(color)
    t.begin_fill()
    t.color(color)
    t.circle(radius)
    t.end_fill()

def Mickey():
    r = 50
    DCircle(0,0,'blue',2*r)
    DCircle(-50,40,"red",r)
    DCircle(50,40,"red",r)

def Main():
    Mickey()
    turtle.done()
    turtle.bye()
    turtle.getscreen()._root.mainloop()

Main()

You haven't positioned correctly! I think in your code you created eye function but never use that, but you don't need that function anyway. We can do anything circular in DCircle function.

Edit : You can Mickey function this then you will get as you say 2 eyes and 2 ears!

def Mickey():
    r = 50
    DCircle(0,0,2*r,'blue')
    DCircle(-135,115,r,'red')
    DCircle(135,115,r,'red')
    DCircle(-50,100,20,"red")
    DCircle(50,100,20,"red")

I don't think you need to make that eye function!

What's you are doing wrong in your code :

1. First thing, you haven't call that eye function, and you are expecting to work. You have to call that function first then only it will work.
2. There is an error in t.color(red) you can't write color name like this, color name should always be string!
3. If you have fixed all above wrong things, then also you only get left eye cuz you have hard coded the position of turtle like this t.setposition(-50,40) .
4. If you to hard code the eyes then, you have to make 2 function. One for left and second for eye.
5. Twist : You don't have to create new functions, you can use DCircle function to do all these things, you have already made dynamic function to make any type of circle then, why you need to make new function and over complicate the things.
