用Python turtle库画一个熊二的卡通头像

好的，我可以为您提供如下代码：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("#F7D267")
pen = turtle.Turtle()

# 画熊二的耳朵
pen.penup()
pen.goto(-50,100)
pen.pendown()
pen.fillcolor("#C93930")
pen.begin_fill()
pen.circle(50)
pen.end_fill()
pen.penup()
pen.goto(50,100)
pen.pendown()
pen.fillcolor("#C93930")
pen.begin_fill()
pen.circle(50)
pen.end_fill()

# 画熊二的脸
pen.penup()
pen.goto(0,-60)
pen.pendown()
pen.fillcolor("#F5B247")
pen.begin_fill()
pen.circle(100)
pen.end_fill()

# 画熊二的眼睛
pen.penup()
pen.goto(-40,40)
pen.pendown()
pen.fillcolor("#FFFFFF")
pen.begin_fill()
pen.circle(25)
pen.end_fill()
pen.penup()
pen.goto(40,40)
pen.pendown()
pen.fillcolor("#FFFFFF")
pen.begin_fill()
pen.circle(25)
pen.end_fill()

# 画熊二的鼻子
pen.penup()
pen.goto(0,0)
pen.pendown()
pen.fillcolor("#000000")
pen.begin_fill()
pen.circle(20)
pen.end_fill()

# 画熊二的嘴巴
pen.penup()
pen.goto(-40,-40)
pen.pendown()
pen.setheading(-45)
pen.circle(30,90)

# 隐藏画笔
pen.hideturtle()

# 显示画面
canvas.mainloop()

您可以将代码复制到Python编辑器中并运行，即可看到熊二的卡通头像。
