drawsnake函数定义没看明白

嘴角向上

import turtle
def drawSnake(rad,angle,len,neckrad):
    for i in range(len):
        turtle.circle(rad,angle)
        turtle.circle(-rad,angle)
    turtle.circle(rad,angle/2)
    turtle.fd(rad)
    turtle.circle(neckrad+1,180)
    turtle.fd(rad*2/3)
def main():
    turtle.setup(1300,800,0,0)
    pythonsize=10
    turtle.pensize(pythonsize)
    turtle.pencolor("blue")
    turtle.seth(30)
    drawSnake(40,60,5,pythonsize/2)
main()
上面为什么多次使用 turtle.circle

newu

turtle库中circle()函数是用来画弧的。
