python 利用turtle库绘制笑脸和哭脸的例子

我就废话不多说了，直接上代码吧！

import turtle
turtle.pensize(5)
turtle.pencolor("yellow")
turtle.fillcolor("red")
turtle.penup()
turtle.goto(0,-200)
turtle.pendown()
turtle.circle(200)

turtle.penup()
turtle.goto(-100,50)
turtle.pendown()
turtle.begin_fill()
turtle.circle(17.5)
turtle.end_fill()

turtle.penup()
turtle.goto(100,50)
turtle.pendown()
turtle.begin_fill()
turtle.circle(17.5)
turtle.end_fill()

turtle.penup()
turtle.goto(0,50)
turtle.pendown()
turtle.circle(-70,steps=3)

turtle.penup()
turtle.goto(-100,-70)
turtle.pendown()
turtle.right(90)
turtle.circle(100,180)
turtle.mainloop()#结果如下

import turtle
turtle.pensize(5)
turtle.pencolor("green")
turtle.fillcolor("red")
turtle.penup()
turtle.goto(0,-200)
turtle.pendown()
turtle.circle(200)

turtle.penup()

turtle.end_fill()

turtle.penup()
turtle.goto(100,50)
turtle.pendown()
turtle.begin_fill()
turtle.circle(17.5)
turtle.end_fill()

turtle.penup()
turtle.goto(0,50)
turtle.pendown()
turtle.circle(-70,steps=3)

turtle.penup()

turtle.pendown()
turtle.left(90)
turtle.circle(-50,180)

turtle.mainloop()#结果如下
