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=30
    turtle.pensize(pythonsize)
    turtle.pencolor("blue")
    turtle.seth(-40)
    drawSnanke(40,80,5,pythonsize/2)
 
main()

你定义的是

drawSnake

而调用的却是

drawSnanke(40,80,5,pythonsize/2)

多了个n了

另外，你上面的错与你上面的程序不配，turtle,circle(-rad, angle),是逗号错了，应该是点。
