python怎么画笑脸 如何用python画笑脸

我正在开发一个涉及游戏的程序，该程序将根据用户输入更改笑脸(使用乌龟绘制)。 程序启动时，将绘制一张规则的笑脸(黄色的脸，黑色的眼睛和嘴巴，微笑)。 然后，通过以下菜单提示用户更改面孔：

换脸

1)让我皱眉

2)让我生气

3)让我的眼睛变蓝

0)退出

输入选择：

如果用户选择1，则将笑脸重新绘制，皱眉变成微笑，菜单将更改为：

换脸

1)让我微笑

2)让我生气

3)让我的眼睛变蓝

0)退出

输入选择：

如果用户选择2，将重新绘制笑脸并用皱眉填充红色，菜单将更改为：

换脸

1)让我微笑

2)让我开心

3)让我的眼睛变蓝

0)退出

输入选择：

我很难根据用户输入更改笑脸。 我该如何改变笑脸？

据我所知，请帮助！：

import turtle
turtle.up()
turtle.goto(0, -100) # center circle around origin
turtle.down()
turtle.begin_fill()
turtle.fillcolor("yellow") # draw head
turtle.circle(100)
turtle.end_fill()
turtle.up()
turtle.goto(-67, -40)
turtle.setheading(-60)
turtle.width(5)
turtle.down()
turtle.circle(80, 120) # draw smile
turtle.fillcolor("black")
for i in range(-35, 105, 70):
turtle.up()
turtle.goto(i, 35)
turtle.setheading(0)
turtle.down()
turtle.begin_fill()
turtle.circle(10) # draw eyes
turtle.end_fill()
class Face:
def __init__(self):
self.__smile = True
self.__happy = True
self.__dark_eyes = True

menu = int(input("Enter a selection: "))
if menu == 1:
face.change_mouth()
face.draw_face()
elif menu == 2:
face.change_emotion()
face.draw_face()
elif menu == 3:

如何实现乌龟代码，以便可以根据用户输入绘制笑脸？
